Development of Energy Dissipation System for Mid-to-high-rise Wooden Structure

本研究针对木框架结构的抗震性能，提出两种耗能减震结构体系。一种是利用油阻尼器作为肘撑安装，以增加结构的吸收能量。另一种体系通过连接木梁和木柱的宽翼缘的塑性变形来耗散地震能量。通过一系列的试验和分析研究，证实了这两种结构体系都能改善木框架结构在强震作用下的地震反应。

In this research, two types of energy dissipation structural systems are developed in order to enhance seismic performance of wooden frame structures. The one makes use of an oil damper mounted as a knee-brace to increase absorbing energy of the structure. The other system dissipates seismic energy due to plastic deformation of wide flange shapes which is used to connect wooden beams and columns. Through a series of experimental and analytical studies, it is confirmed that both of the structural system can improve seismic response of wooden frame structures subjected to strong ground motions.
