大行程墙式铅剪切阻尼器试验研究和工程计算

Experimental study and engineering application of long stroke lead shear damper

目前,我国对建筑结构耗能设备的行程提出了更高的需求,大行程的减震耗能设备亟需研发。提出了一种适用于建筑结构的墙式铅剪切阻尼器并进行了试验,在此基础上,通过对实际结构进行有限元分析得到墙式大行程铅剪切阻尼器的实际减震效果。结果表明该种阻尼器具有较好的消能减震能力,能够在多遇及罕遇地震中多遇地震作用下提升建筑结构的耗能能力。

At present,there is a higher demand for the travel of energy consuming equipment in building structures in China,and there is an urgent need for research and development of shock absorption energy consuming equipment with large travel.This article proposes a wall type lead shear damper suitable for building structures and conducts experiments.Based on this,the actual seismic reduction effect of the wall type long stroke lead shear damper is obtained through finite element analysis of the actual structure.The results indicate that this type of damper has good energy dissipation and seismic reduction capabilities,and can enhance the energy dissipation capacity of building structures under frequent and rare earthquakes.
