基于位移控制的低层框架抗震加固和加层的新思路

Aseismic Strengthening and Addition Stories of Lower Frame Based on Control of Displacement

比较了采用通常的抗震加固、加层的方法对一框架结构加固加层的效果。针对其中存在的不足 ,提出一种基于位移控制的低层框架抗震加固、加层的新思路、新方法 ,供同类工程设计时参考。

Because the old kinds of methods of aseismic strengthening and floor adding are not very ideal for one frame strucutre,the authors introduce a new method of aseismic strengthening and floor adding for low\|rise frame structure,which is based on displacement control.
