地震作用下高桩承台桥梁结构工程简化模型的研究与分析

Study and Analysis of High-pile Base Slab Bridge Structure Engineering Simplifying Model under Seismic Action

目前考虑桩土相互作用的结构抗震分析中常采用Penzien模型,Penzien模型虽然比较简单,但在实际工程计算中仍然很繁琐。讨论高桩承台结构工程简化模型的参数确定方法,并用Penzien模型对其进行校核,结果表明,工程简化模型计算上部结构的地震响应有着一定的适用性。

Penzien model is often considered to use in the structural seismic analysis of pile-soil interaction.Penzien model is simpler,but it is still more minute and complicated in the calculation of practical engineering.The article discusses the parameter defining method of engineering simplifying model for the high-pile base slab structure,and checks it by Penzien model.The result shows that the engineering simplifying model to calculate the seismic response of the superstructure has some applicability.
