摘要:
针对传统桥梁减隔震支座性能单一，无法满足正常使用荷载及地震极端荷载等不同工况的现状，设计了一种新型多功能滑移减隔震支座，通过理论分析与有限元模拟相结合的方式建立了该多功能支座的剪切性能曲线，并阐述了该曲线的力学特性及各个关键点的意义。在此基础上，进行了压缩性能、剪切性能及其相关性试验。结果表明：新型多功能滑移减隔震支座能够达到预期目标，可同时满足桥梁在正常使用阶段的滑移和地震作用下的耗能要求；支座剪切性能曲线的有限元分析结果与试验结果吻合良好，有限元分析得到的剪切性能曲线可有效描述其力学行为；所得结论为后续桥梁减隔震设计及动力时程分析提供了参考
Abstract:
The traditional bridge slidingisolation bearings performance was single and couldnt meet the situation in different cases, such as normal load, severe seismic load, etc.In order to solve the problem, a new type of multifunctional slidingisolation bearing was designed. Combining the theoretical analysis and finite element simulation, the shear behavior curve of the new type multifunctional slidingisolation bearing was established. The mechanical property and the meaning of each key point of the curve were explained. Based on this, the correlation experiments on the compression behavior, shear behavior of the slidingisolation bearing were carried out. Results show that the new type of multifunctional slidingisolation bearing can achieve the predicted target. The developed bearing can meet the bridge demands of sliding in normal use and energy dissipation under earthquake action. Moreover, the finite element analysis results of shear behavior curve of bearing agree well with the experiment results. Therefore, the theoretical shear behavior curve can effectively reflect the mechanical property of bearing. The obtained results can provide basis for slidingisolation design and dynamic timehistory analysis of the bridges in the future.
