摘要
Abstract
The beam-shear key pounding effect is the direct factor to cause shear key of a bridge damage. In order to quantitatively analyze the change of bridge transverse seismic response caused by collision, the Kelvin contact element model and the SSH numerical calculation method are used to derive the numerical calculation method and procedure for bridge transverse seismic response considering the beam-shear key pounding effect. And MATLAB language is used to develop the computer program. According to the comparison of calculational result and test result obtained by reference, it shows that the proposed method is computationally efficient and accurate. A example is given to introduce the practicability of the proposed method.关键词
