底框砌体剪力墙震损房屋抗震加固拟动力子结构试验

Experimental Analysis of Seismic Performance of Strengthening Frame-supported Reinforced Concrete Masonry Short-leg Shear Wall Structure Damaged by Earthquake Using the Sub-structure Pseudo-dynamic Test

在完成了3层足尺底框配筋砌块短肢砌体剪力墙震损房屋损伤程度的评估、加固的基础上,通过对加固后的3层房屋进行拟动力抗震性能试验,研究了震后受损结构构件所用加固方法的适用性和加固对恢复结构抗震性能的效果,为寻求震损结构加固修复的方法提供理论依据,并为汶川地震受损底框房屋的结构修复提供参考。

Based on the damage assessment and strengthening scheme of the full-scale model which is the three-floor frame-supported reinforced concrete masonry short-leg shear wall structure,the strengthened model is tested using the substructure pseudo-dynamic testing method.The applicability of the proposed strengthening technique for the building damaged by earthquake is discussed.Thus,the seismic performance of the strengthened model is proposed to seek the strengthening technique for the structure damaged by earthquake,and it provides important reference for the post-disaster reconstruction after Wenchuan earthquake.
