Texto completoThe analysis of test results in order to extract the principal design information was carried out using an Equivalent Energy Elastic-Plastic (EEEP) model. A ductility related (Rd) and an overstrength related (Ro) force modification factor are required for the calculation of equivalent static seismic loads following the 2005 NBCC design provisions. Values of Ro = 1.8 and Rd = 2.5 have been determined and are recommended on a preliminary basis.
The Stewart hysteretic model was found to best represent the strength and stiffness characteristics of a steel frame/wood panel shear wall component. The subsequent evaluation of building models that incorporate the Stewart model using non-linear time history dynamic analyses could then be carried out to validate the assumptions made by the EEEP method on the system ductility and the corresponding force modification factors.

Texto completoThis thesis has two main objectives. One is to investigate the performance characteristics of various configuration light gauge steel frame/wood panel shear walls under monotonic and reversed cyclic loading. The second is to recommend an effective analytical model, which relies on sheathing-to-framing connection test results and the mechanical properties of structural sheathing and steel frame members, to predict the resistance and deflection of shear walls subjected to lateral loads.

Texto completoA comprehensive database of monotonic and reversed cyclic tests on steel frame/wood panel shear walls is needed to obtain different wall parameters for use in design. For this particular project 1220 x 2440 mm walls (3 wall configurations for a total of 18 specimens) composed of 1.09 mm thick 230 MPa grade steel and 9.0 mm thick OSB were tested; where the screw spacing along the perimeter of the wall was varied (75, 100 & 152 mm). The equivalent energy elastic-plastic (EEEP) analysis approach was employed to derive design values from the test results; such as stiffness, strength and a resistance factor for use with the 2005 NBCC, as well as ductility and overstrength modification factors. The resistance factor, o = 0.7, determined by Branston was confirmed. Ductility related, Rd = 2.5, and overstrength related, R0 = 1.8, seismic force modification factors are recommended for use with shear wall design values that are based on the EEEP analysis approach.
Furthermore, the test data were used to create and calibrate hysteretic models, with the Stewart element, which later were used in non-linear time history dynamic analyses. The Ruaumoko software was made use of for the modeling of two representative buildings with ten earthquake records for the Vancouver BC region. The shear wall system of a typical two-storey house and a three-storey commercial building was first designed for lateral loads and then modeled. The resulting shear deformations (rotations) obtained from the analyses were compared with the limiting parameters measured during the physical shear wall tests. It was found that the scaled ground motions caused a shear demand that did not exceed the test based deformation limits.

Texto completozce provinces in Turkey with magnitudes (Mw) 7.4 and 7.1, respectively. These catastrophes caused substantial structural damage, casualties and loss of lives. In the aftermath of these destructive earthquakes, neither demolished nor damaged shear-wall dominant buildings constructed by tunnel form techniques were reported. In spite of their high resistance to earthquake excitations, current seismic code provisions including the Uniform Building Code and the Turkish Seismic Code present limited information for their design criteria. This study presents experimental investigation of the panel unit having H-geometry. To investigate the seismic behavior of panel buildings, two prototype test specimens which have H wall design were tested at the Structural Mechanics Laboratory at METU. The experimental work involves the testing of two four-story, 1/5-scale reinforced concrete panel form building test specimens under lateral reversed loading, simulating the seismic forces and free vibration tests. Free vibration tests before and after cracking were done to assess the differences between the dynamic properties of uncracked and cracked test specimens. A moment-curvature program named Waller2002 for shear walls is developed to include the effects of steel strain hardening, confinement of concrete and tension strength of concrete. The moment-curvature relationships of panel form test specimens showed that walls with very low longitudinal steel ratios exhibit a brittle flexural failure with very little energy absorption. Shear walls of panel form test specimens have a reinforcement ratio of 0.0015 in the longitudinal and vertical directions. Under gradually increasing reversed lateral loading, the test specimens reached ultimate strength, as soon as the concrete cracked, followed by yielding and then rupturing of the longitudinal steel. The displacement ductility of the panel form test specimens was found to be very low. Thus, the occurrence of rupture of the longitudinal steel, as also observed in analytical studies, has been experimentally verified. Strength, stiffness, energy dissipation and story drifts of the test specimens were examined by evaluating the test results.

Texto completoThe analysis of reinforced concrete panels submitted to in-plane shear has received the attention of researchers along the years. It is mainly due to the difficulty to simulate the application of the external loads and the structural boundary conditions. The purpose of this work is to present a numerical model to represent reinforced concrete panels submitted to inplane shear. In the computational analysis via Finite Elements, an embedded crack model that considers the inclusion of the reinforcement contribution in the internal force equilibrium of the element is presented. This type of model is based in discontinuities embedded into standard finite elements. The implemented formulation uses the model presented by Dvorkin, Cuitiño and Gioia (1990), which does not have the reinforcement contribution in the element internal equilibrium. The adherence stress transfer model of Russo, Zingone and Romano (1990) is used to include this reinforcement contribution. An embedded model was employed to represent the reinforcement bars, allowing that they can be placed in an independent position and shape in the FEM elements. The numerical results are compared with Vecchio’s work. Also are included two different dowel action models (transversal shear resistance of the bars) and is studied their influence in the panels’ behavior. Panels with different experimental rupture modes were simulated with good responses in the most cases. Comparisons of shear stress x shear strain curve with and without dowel action are performed, showing the importance of this effect on the global response.

Vessby, Johan. "Shear walls for multi-storey timber buildings". Licentiate thesis, Växjö University, School of Technology and Design, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:vxu:diva-2420.
Texto completoWind loads acting on wooden building structures need to be dealt with adequately in order to ensure that neither the serviceability limit state nor the ultimate limit state is exceeded. For the structural designer of tall buildings, avoiding the possibly serious consequences of heavy wind loading while taking account at the same time of the effects of gravitation can be a real challenge. Wind loads are usually no major problem for low buildings, such as one- to two-storey timber structures involving ordinary walls made by nailing or screwing sheets of various types to the frame, but when taller structures are designed and built, serious problems may arise.
Since wind speed and thus wind pressure increases with height above the ground and the shear forces transmitted by the walls increase accordingly, storey by storey, considerable efforts can be needed to handle the strong horizontal shear forces that are exerted on the bottom floor in particular. The strong uplift forces that can develop on the wind side of a structure are yet another matter that can be critical. Accordingly, a structure needs to be anchored to the substrate or to the ground by connections that are properly designed. Since the calculated uplift forces depend very much upon the models employed, the choice of models and simplifications in the analysis that are undertaken also need to be considered carefully.
The present licentiate thesis addresses questions of how wind loads acting on multi-storey timber buildings can be best dealt with and calculated for in the structural design of such buildings. The conventional use of sheathing either nailed or screwed to a timber framework is considered, together with other methods of stabilizing timber structures. Alternative ways of using solid timber elements for stabilization are also of special interest.
The finite element method was employed in simulating the structural behaviour of stabilizing units. A study was carried out of walls in which sheathing was nailed onto a timber frame. Different structural levels were involved, extending from modelling the performance of a single fastener and of the connection of the sheathing to frame, to the use of models of this sort for studying the overall structural behaviour of wall elements that possess a stabilizing function. The results of models used for simulating different load cases for walls agreed reasonably well with experimental test results. The structural properties of the fasteners binding the sheathing to the frame, as well as of the connections between the members of the frame were shown to have a strong effect on the simulated behaviour of shear wall units.
Regarding solid wall panels, it was concluded that walls with a high level of both stiffness and strength can be produced by use of such panels, and also that the connections between the solid wall panels can be designed in such a way that the shear forces involved are effectively transmitted from one panel to the next.

Texto completoShear beams and shear walls were constructed using varying amounts of steel fibers and rubber to determine the effect of these constituents on concrete when subject to shear loads and reversed cyclic loadings. 22 concrete beams were tested using mixes with differing amounts of fibers and rubber. The beams were designed to fail in shear by applying a single downward point load at midspan using a MTS Universal Testing Machine. Using the recorded load and displacement data the behavior of each beam and the shear strength contribution for each mix were determined. For all mixes that included fibers and/or rubber the shear strengths increased 12% to 56% in comparison to the plain concrete mixes. Four concrete walls were also tested using four of the 22 beam mixes. The four selected mixes were chosen based on the comparable compressive strengths and mix constituents. The walls were designed to fail in shear by applying a lateral load to a top block cast on top of the shear wall. The walls were tested on a modular strong-block test system within a rigid steel frame so that the load could be applied by a hydraulic actuator. During testing, the displacement at 10 selected locations, the loads placed on the walls at each displacement, and the behavior were recorded and analyzed. The walls containing rubber experienced lower strengths, a brittle failure with severe spalling and damage, and dissipated a low amount of energy. The walls containing fibers exhibited strain hardening characteristics leading to a ductile failure mode, higher strengths, and little web damage. Using the findings from this study, it can be concluded that both fibers and rubber can be used to increase shear strength but only fibers were found to be a viable option for application in walls subject to reverse cyclic loadings.

Tilt-up construction is becoming more popular in the United States due to its ease of construction, reliability, and relatively low construction and maintenance costs. In its most typical form, a concrete panel is cast on the ground. After the concrete sets and has reached a prescribed compressive or flexural strength, a crane lifts the panel off the ground and hoists it into place. The flexural stresses during liftoff are often times greater than those corresponding to service loads. Concentrations of high shear stress and the associated punching shear in the vicinity of the pick points could result in pullout. For these reasons, it is particularly important to design the concrete and steel reinforcement to handle the flexural and shear stresses associated with panel erection. This thesis investigates the flexural stresses and punching shear of a concrete panel designed for tilt-up. Finite element models confirm static hand calculations, and experimental results indicate that these models appropriately predicted erection stresses. The acceptability of the design provided is confirmed.

Texto completoGenom att minska vikten på lastbilen frigörs mer last att bäras av släpvagnen. Detta har en betydande inverkan på effektiviteten hos transporten som sänker både den totala kostnaden för transporterad last och de totala koldioxidutsläppen. Hälften aven lastbils rena karossvikt består av paneler gjorda av tunt mjukt formningsstål vilke tinte kan bli tunnare för att minska vikten på grund av den sänkta styvheten som detskulle medföra. Sandwichmaterial har en hög styvhet till viktförhållande och skulle församma paneltjocklek som vanligt formningsstål ha en jämförbar böjstyvhet men sänkt vikt. Denna uppsats är avsedd att vara en preliminär studie för Scania CV AB om sandwichmaterial och dess potentiella användning av lättvitkspaneler i lastbilar.Med avsikt att undersöka huruvida ett kommersiellt sandwichmaterial kan fylla rollen som lastbilens ytterpaneler utfördes jämförande tester med avseende på signifikanta frågor såsom formning och målning på identiskt tillverkade demonstratorer som jämförde ett sandwichmaterial och ett vanligt formningsstål. Testerna identifierade svagheter med materialet samt hur processen behöver anpassas för att kunna använda sandwichmaterialet i rådande tillverkningsprocess. Identifierade problem var bland annat problem med målning och sammanfogning på grund av isolerade ytterskickt i sandwichmaterialet, problem med formning som gav upphov till limdragningar som troligen beror på materialets olika återfjädring samt falsningsfel på grund av otillräckligt optimerad falsteknik och anisotropi. Nu när mer kunskap om sandwichmaterial erhållits kan motåtgärder för de funna resultaten undersökas för att ta ytterligare ett steg mot att sänka lastbilens vikt och därmed få ett effektivare transportmedel.
