Full textThis report investigates the down-aisle buckling load capacity of steel storage rack uprights. The effects of discrete torsional restraints provided by the frame bracing in the cross-aisle direction is considered in this report. Since current theoretical methods used to predict the buckling capacity of rack uprights appear to be over-conservative and complex, this research may provide engineers an alternative method of design using detailed finite element analysis. In this study, the results from experimental testing of upright frames with K-bracing are compared to finite element predictions of displacements and maximum axial loads. The finite element analysis is then used to determine the buckling loads on braced and un-braced uprights of various lengths. The upright capacities can then be compared with standard design methods which generally do not accurately take into account the torsional resistance that the cross-aisle frame bracing provides to the upright. The information contained in this report would be beneficial to engineers or manufacturers who are involved in the design of rack uprights or other discretely braced complex light gauge steel members subject to axial loads.

Full textSyfte: Genom åren har forskning gjorts som tyder på att när man kombinerar stål ochträ kommer det bidra till en ökad hållfasthet. Under optimala förhållande är trä ettotroligt effektivt och bra alternativ inom byggande då det är billigt och tåligt. Närstålbalkar däremot placeras i optimala förhållande kan de bibehåll betydligt mer ochstörre krafter än vad trävirke kan göra. Att kombinera stål och trä har de senaste årethaft ett ökat intresse. Studier visar att hybridbalkar kan vara till stor ekonomisk fördelvid byggnation av flervåningshus, då det kan ersätta eller komplettera rena stålstommar.Syftet med arbete är att öka kunskapen och förståelsen för hur stål och trä samverkarsamt ta reda på för och nackdelar hos de stålförstärkta träbalkarna samt jämföra deraslastkapacitet med konstruktionsträ- och limträbalkar.Metod: Arbetet omfattar en kvantitativ studie där två typer av datainsamlingsmetoderhar använts. Dessa två typer är beräkningar samt litteraturstudier. Litteraturstudienbestår av vetenskapliga artiklar som har hjälpt besvara en av frågeställningarna.Beräkningarna har använts för att besvara båda frågeställningarna, de har gjorts idimensioneringsprogrammet Tekla tedds som följer alla Eurocodes beräknings- ochdimensioneringsregler.Resultat: Resultaten visar på att den stålförstärkta träbalken har högre kapacitet änlimträ och konstruktionsvirke, både med hänsyn till nedböjning och brott men betydligthögre pris och egentyngd. Den stålförstärkta träbalken klarar även av längrespännvidder vid samma belastning.Konsekvenser: Utifrån de resultat rapporten kommit fram till är det svårmotiverat attanvända sig av de stålförstärkta balkarna i bjälklag på grund av det höga priset Denstålförstärkta träbalken klarar dock av högre laster än vad konstruktionsvirke och limträgör, vilket kan göra balken användbar som avväxlingsbalk. Att använda denstålförstärkta träbalken som avväxlingsbalk kan motivera det höga priset då den kanhålla mindre dimensioner än limträ och konstruktionsvirke vilket kan vara önskvärt iolika sammanhang.Begränsningar: De begränsningar som sattes för rapporten var att utesluta alla typerav miljörisker på balkarna som tillexempel fukt och solljus vid beräkningarna, då entorrmiljö är en optimal miljö för både trä och stål. Beräkningarna som arbetet baseraspå grundar sig på Eurocodes dimensioneringsregler. Andra typer av dimensioneringsprinciper har uteslutits.

Full textAs colunas estaiadas podem ser utilizadas como elementos resistentes à compressão de uma estrutura que apresente elevada esbelteza e requisitos de montagem rápida. Colunas estaiadas pré-esforçadas (CEPE) é uma solução que visa aumentar a capacidade de carga em colunas esbeltas. Para tal, à coluna esbelta acrescentou-se um sistema de pré-esforço composto por tirantes pré-esforçados e braços que restringem ao longo do comprimento.Desde 1960 que vários investigadores realizam estudos experimentais, numéricos e analíticos sobre esta solução estrutural, mas o seu comportamento estrutural não é completamente compreendido.No âmbito do projeto HILONG foram realizadas análises experimentais e com essas foi desenvolvido um modelo de elementos finitos calibrado em função dessas experiências. A presente dissertação visa a realização de um estudo paramétrico extensivo baseado na simulação calibrada de elementos finitos fazendo variar o comprimento da coluna, a seção transversal, o nível de pré-esforço nos tirantes, a seção dos tirantes e o tipo do aço.Realizaram-se no total 1008 análises numéricas, 648 LBA (18 colunas*3 espessuras da coluna principal*6 níveis de pré-esforço*2 cabos) e 360 GMNIA (12 colunas*3 espessuras da coluna principal*5 níveis de pré-esforço*2 cabos*1nível de pré-esforço (L/1000)), usando o programa de elementos finitos ABAQUS.Conclui-se com o estudo paramétrico que a adição do sistema de pré-esforço é mais eficiente em colunas mais esbeltas, porque fornece restrições adicionais que aumentam a capacidade máxima da coluna. Verificou-se que o uso de tirantes com maior seção transversal e a menor espessura para a seção transversal da coluna principal obteve um benefício mais significativo na capacidade de carga da coluna.
The stayed columns can be used as compression resistant elements of a structure that presents high slenderness and fast assembly requirements.Prestressed stayed columns (PSSC) is a solution that aims to increase the load capacity in slender columns. To this end, a prestressed system composed of prestressed stays and cross-arms that restrict along the length were added to slender column.Since 1960, researchers have been investigated experimentally, numerically and analytically on this structural solution, but its structural behavior is not completely understood. In the scope of the HILONG project, experimental analysis was performed and a finite element model calibrated according to these experiments was developed.The present dissertation focusses on the performance of an extensive parametric study based on the calibrated simulation of finite elements by varying the length of the column, the cross section, the level of prestressed initial in stays, the section of the stays and steel grade.In total, 1008 numerical analysis, 648 LBA (18 columns*3 main column thickness*6 prestress level*2cables) and 360 GMNIA (12 columns*3 main columns thickness*5 prestress level*2 cables*1 amplitude of geometric imperfections (L/1000)) were carried out using the finite element software ABAQUS.It is concluded with the parametric study that the addition of the stay system is more efficient in slender columns because provides additional restrains that increases the ultimate capacity of column. It was found that the use of stays with larger cross section and the smaller thickness for the cross section of the main columns obtained a more significant benefit on the load carrying capacity of long columns.
