一座木结构模型的振动台实验研究

Study on the seismic behaviors of wooden structure by shaking table test

通过对木结构模型的振动台实验,讨论木结构模型实验体的动力测试方法,确定木结构构筑物在地震作用下的破坏机理,同时讨论了节点动力特性.研究了结构动力特性及地震反应的变化规律.通过实验可知在地震荷载作用下节点变形是非常重要的破坏准则,为危旧住房以及农村乡镇住房的抗震加固寻找有效且经济可行的方法.

By testing a wooden structure on a shaking table, to discuss the dynamic testing method for wooden structures and the destroying principles during dynamic load. It also discusses the mechanical characteristic of column-beam joints. The dynamic characteristics and the change rules of frequency and damping ratio were tested. The seismic responses of the model were also obtained. It shows that joint deformation plays very important rules during seismic load. By discussion test result, author wants to show an economical and effective retrofitting method for old houses in the countryside.
