The dynamic characteristics of long-span suspension bridges are complex. natural vibration frequency is changed with different structural parameters, and the sensitivity to parameters different. In order solve this problem, spatial model a bridge was established by using finite element software, first 20 periods, frequencies modes were analyzed calculated. accuracy obtained data verified throug...

A suspended monorail transit system is a category of urban rail transit, which is effective in alleviating traffic pressure and injury prevention. Meanwhile, with the advantages of low cost and short construction time, suspended monorail transit systems show vast potential for future development. However, the suspended monorail has not been systematically studied in China, and there is a lack o...

The analysis based on an ideal state as well as the simulation and control to reach it are common issues in the design and construction of a cable-stayed bridge. For a long-span cable-stayed bridge, the huge initial stress accumulated in the pylon and the girder will reduce the overall structure stiffness. Thus, the live load evaluation employing influence lines, which is based on the Muller-Br...

In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration, nonlinear parametric vibration and wind f...

performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...

The goal of this study is to investigate the behavior and failure mechanism historical Irgandi Bridge located in Bursa City under earthquake loads by using linear nonlinear dynamic analysis. Dynamic characteristics bridge investigated in-situ Operational Modal Analysis (OMA) tests. finite element model updated according OMA Three different artificial records from weak very strong are applied fo...
