Full textThe unsteady buffeting forces and the gust response prediction of bridges in the atmospheric turbulent flows is recently attracted more attention due to uncertainties in both experiment and analytical theory. The correction functions such as the aerodynamic admittance function and the spatial coherence function have been supplemented to cope with limitations of the quasi-steady theory and strip one so far. Concretely, so-called single-variate quasi-steady aerodynamic admittance functions as the transfer functions between the wind turbulence and induced buffeting forces, as well as coherence of wind turbulence has been widely applied for the gust response prediction. Recent literatures, however, pointed out that the coherence of force exhibits higher than that of turbulence. These correction functions, in the other words, contain their uncertainties which are required to be more understanding. Proper orthogonal decomposition (POD), known as the Karhunen-Loeve decomposition has been applied popularly in many engineering fields. Main advantage of the POD is that the multi-variate correlated random fields/processes can be decomposed and described in such simplified way as a combination of limited number of orthogonally low-order dominant eigenvectors (or turbulent modes) which is convenient and applicable for order-reduced representation, simulation of the random fields/processes such as the turbulent fields, turbulent-induced force fields and stochastic response prediction as well. The POD and its proper transformations based on either zero-time-lag covariance matrix or cross spectral one of random fields/processes have been branched by either the covariance proper transformation (CPT) in the time domain or the spectral proper transformation (SPT) in the frequency domain. So far, the covariance matrix-based POD and its covariance proper transformation in the time domain has been used almost in the wind engineering topics due to its simplification in computation and interpretation. In this research, the unsteady buffeting forces and the gust response prediction of bridges with emphasis on the POD applications have been discussed. Investigations on the admittance function of turbulent-induced buffeting forces and the coherence one of the surface pressure as well as the spatial distribution and correlation of the unsteady pressure fields around some typically rectangular cylinders in the different unsteady flows have been carried out thanks to physical measurements in the wind tunnel. This research indicated effect of the bluff body flow and the wind-structure interaction on the higher coherence of buffeting forces than the coherence of turbulence, thus this effect should be accounted and undated for recent empirical formulae of the coherence function of the unsteady buffeting forces. Especially, the multi-variate nonlinear aerodynamic admittance function has been proposed in this research, as well as the temporo-spectral structure of the coherence functions of the wind turbulence and the buffeting forces has been firstly here using the wavelet transform-based coherence in order to detect intermittent characteristics and temporal correspondence of these coherence functions. In POD applications, three potential topics in the wind engineering field have been discussed in the research: (i) analysis and identification, modeling of unsteady pressure fields around model sections; (ii) representation and simulation of multi-variate correlated turbulent fields and (iii) stochastic response prediction of structures and bridges. Especially, both POD branches and their proper transformations in the time domain and the frequency one have been used in these applications. It found from these studies that only few low-order orthogonal dominant modes are enough accuracy for representing, modeling, simulating the correlated random fields (turbulence and unsteady surface pressure, unsteady buffeting forces), as well as predicting stochastic response of bridges in the time and frequency domains. The gust response prediction of bridges has been formulated in the time domain at the first time in this research using the covariance matrix-based POD and its covariance proper transformation which is very promising to solve the problems of the nonlinear and unsteady aerodynamics. Furthermore, the physical linkage between these low-order modes and physical causes occurring on physical models has been interpreted in some investigated cases.

The developments of bridge construction techniques and the improvements of high strengh materials have made the modern bridges designed and built towards longer spans with more slender sections. Because these types of bridges are more flexible than the other types of bridges, they are more susceptible to wind excitation. To strengthen the weakness of these types of bridges, some devices must be used to control the wind effects. Among these devices, tuned mass dampers have been installed in some existed bridges, and their performance is proven to be effective against wind-induced vibrations. In the wind-induced buffeting problems of the long-span bridges, the vertical and torsional displacements are always the major concerns for the bridge engineers. However, the traditional tuned mass dampers are designed to reduce dynamic response in one direction only. To achieve the goal of suppressing both the vertical and torsional response, the 2 D. O. F. model, with two frequencies that are tuned at the effective frequencies of the first vertical and torsional modes of the bridge, is proposed. The aerodynamic coupling is taken into account for the formulation of the bridge-TMD system. Therefore, this model is specially applicable for those bridges in which mode coupling is significant. A parametric study is performed to investigate the buffeting response reduction and the increase of the flutter velocity. Based on this parametric analysis, the procedures of the TMD design for the wind-exeited bridges are then proposed. The influence of the aerodynamic coupling on the TMD design is also addressed. The results show that the propposed TMD is at least as effective as the usual TMD on suppressing buffeting respponse, and it appreciably raises the stability of the bridge either with the type of stalled or coupled flutter.

As the main spans of bridges become longer, engineers have to assess the wind induced vibration of bridge decks for safety and serviceability. Generally, either the full bridge model wind tunnel test or section model wind tunnel test with analytical procedure is used to evaluate buffeting responses of bridges. Modal parameters, including modal frequencies and damping ratios, are usually obtained by finite element models; aerodynamic parameters, including aerodynamic coefficients and flutter derivatives, are obtained by section model wind tunnel test. In this research, modal and aerodynamic parameters are obtained by identifying filed measurement results and numerical simulations respectively. This study proposes a method, combing empirical modal decomposition, random decrement technique with Hilbert transform, for identification of modal parameters in time domain from modally coupled response time histories. Aerodynamic and aeroelastic phenomena of blunt sections are simulated by numerical simulations; the associated aerodynamic coefficients are evaluated; flutter derivatives are identified by stochastic subspace identification method. Vortex shedding and reattachment phenomena are observed in the simulated results. The obtained aerodynamic parameters are compared with those of the wind tunnel test in the literature, and indicated that aerodynamic coefficients approach to the average of wind tunnel test results, flutter derivatives are higher estimated slightly. Finally, numerical simulations are conducted for a bridge section; the interaction effect of fluid-bridge section is accounted by an arbitrary Lagrangian-Eulerian strategy. Finally, the root mean square values of bridge buffeting responses are evaluated by an approximate analytic formula using the obtained parameters. These results can be used to assess safety and serviceability of the bridge. The effects of modal parameters, aerodynamic coefficient and flutter derivatives on buffeting responses are also investigated.

In general, the most important effects of bridge aerodynamics are flutter and buffeting. In the past, owing to the experimental technique, we always ignore the effects of lateral flutter derivatives, and only consider vertical and torsional flutter derivatives in the flutter and buffeting analysis. However, ignoring the lateral flutter derivatives may not reflect the real aerodynamic behavior of long-span bridges. Such bridges are usually made of lightweight materials and supported by cable systems. The lateral motions on this type of bridges are significant and usually coupled with torsional motions. Three types of bridges, including cable-stayed bridges, suspension bridges and tied arch bridges, are used in the examples. The lateral flutter derivatives, adopted from references, are used in the multi-mode flutter and buffeting analysis. The effects of mode combinations and the lateral flutter derivatives on the flutter wind velocities and buffeting responses of different types of bridges are investigated through a parametric analysis. The results show that the contributions of the lateral-torsional coupling modes and the lateral flutter derivatives on the aerodynamic behavior of bridges increase with bridge span lengths. These effects should be taken account into the aerodynamic analysis for the long-span bridges. The results also reveal that of the flutter derivatives used here can stabilize the aerodynamic effects and can destabilize the aerodynamic effects.

Since Kao-Ping-Hsi Cable-Stayed Bridge has the longest span length in Taiwan, it is more sensitive to wind The study to monitor this bridge and compare the field measurements with buffeting theoretical results becomes an important task. Therefore, this bridge was chosen as the target for monitoring. Two 3D anemometers were installed at the middle point of the longer span to measure wind characteristics. Two sets of velocity censors, respectively installed at the middle point and on third point of the longer span, were used to measure the dynamic responses of the bridge. The aerodynamic behavior of the Kao-Ping-Hsi Cable-Stayed Bridge was analyzed based on the measured data obtained from the field measurements. The data were collected as several typhoons were attacking Taiwan during 2006-2007. Among these typhoons, Typhoon Krosa was the strongest and its maximum 10 min. mean wind speed was as high as 16 m/s. The effects of this typhoon on the bridge are the main concern in this study. The modal frequencies and damping ratios of the bridge were identified by the methods of FDD and MRD, respectively. These identified parameters along with the fitted wind spectrum were substituted into a numerical model to evaluate the buffeting responses of the targeted bridge. The results obtained from the re-analysis, the field measurements, the section model test and the full model test were compared. The comparative study indicates that the differences between the results obtained from the re-analysis and the results measured from the field measurements are 10% in the vertical direction and 30% in the torsional direction. The drag response obtained from re-analysis is only 25% of that measured from the field measurements. The possible reason for this large discrepancy results from high noise in the field measurements. Since turbulent intensities and damping ratios used in the section model tests and the full model tests were different from those identified from the field measurements. The results obtained from the section model tests are still consistent with those from on-site measurements. However, the results obtained from the full model test are much larger than the other results. This is because the reduced wind velocity in the tests is low and the high noise affected the results..
