【摘要】：日本E-Defense振动台在2010年进行的一个4层预应力混凝土框架结构足尺振动台试验为例,通过分析该结构模型在地震作用下的破坏特征,分别应用增大截面法和增设钢支撑法进行加固处理,利用ANSYS软件进行建模分析,采用弹塑性时程分析方法对比两种方法的加固效果。结果表明,增设钢支撑分担了地震作用,有效提高了结构的抗震性能,而增大截面法对预应力混凝土结构的加固效果较小。
[Abstract]:A full-scale shaking table test of a four-story prestressed concrete frame structure carried out by E-Defense shaking table in Japan in 2010 is taken as an example. By analyzing the failure characteristics of the structure model under earthquake action, the reinforcement treatment is carried out by using the method of increasing section and the method of adding steel support, the modeling and analysis is carried out by ANSYS software, and the reinforcement effect of the two methods is compared by the method of elastic-plastic time history analysis. The results show that the addition of steel braces can share the seismic action and effectively improve the seismic performance of the structure, while the reinforcement effect of the section method on prestressed concrete structures is small.
