摘要

摘要: 基于Ti-51at%Ni形状记忆合金(SMA)丝材料性能试验，以结构振动控制理论为依据，针对框架结构剪切型变形的特点，在框架柱反弯点附近设置SMA被动拉索控制装置，分析其控制原理和规律，利用有限元软件检验其控制效果。结果表明，在柱反弯点处设置SMA被动拉索控制装置可对结构地震响应进行有效控制，因此在结构振动控制中具有广阔的应用前景。

Abstract: Based on the time-history analysis of the elastic-plastic wind-induced response for a tall building structure under the strong breeze,the feasibility of the application of Pushover method to the wind resistance design of the structure is investigated.Through a series of comparative analyses for computational results of different methods,it is found that the tall building structures under the weak wind load are generally in the elastic state.The structural responses obtained by using the static-equivalent wind-load method in the code may meet the needs of practical projects.But under the strong breeze,some moments of the tall building structure would enter the plastic deformation state,the displacement responses provided by the Pushover method are in good agreement with the results of the time-history analysis,and the results of the static-equivalent wind-load method is unsafety.
