【摘要】:在罕遇地震作用下,連續(xù)梁橋有時可能進入彈塑性狀態(tài),結合某軌道交通的高架橋梁工程,采用纖維模型,分析了該橋在地震作用下的受力狀態(tài),分析表明,該橋制動墩墩底鋼筋在給定地震時程波作用下發(fā)生屈服,橋墩進入塑性狀態(tài),但非線性位移延性比滿足規(guī)范要求;該計算結果已為該梁的抗震設計提供依據(jù),分析方法可為同類結構提供參考。
[Abstract]:Under the rare earthquake, the continuous beam bridge may enter the elastic-plastic state sometimes. Combined with the elevated bridge project of a certain rail transit, the stress state of the bridge under the earthquake is analyzed by using the fiber model, and the analysis shows that, The steel bar at the bottom of the brake pier of the bridge yields under the action of a given earthquake, and the pier enters a plastic state, but the ratio of nonlinear displacement to ductility meets the requirements of the code, and the calculation results have provided the basis for the seismic design of the beam. The analytical method can provide reference for similar structures.
