【摘要】：日本E-Defense振動臺在2010年進(jìn)行的一個4層預(yù)應(yīng)力混凝土框架結(jié)構(gòu)足尺振動臺試驗為例,通過分析該結(jié)構(gòu)模型在地震作用下的破壞特征,分別應(yīng)用增大截面法和增設(shè)鋼支撐法進(jìn)行加固處理,利用ANSYS軟件進(jìn)行建模分析,采用彈塑性時程分析方法對比兩種方法的加固效果。結(jié)果表明,增設(shè)鋼支撐分擔(dān)了地震作用,有效提高了結(jié)構(gòu)的抗震性能,而增大截面法對預(yù)應(yīng)力混凝土結(jié)構(gòu)的加固效果較小。
[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.
