底框砌体剪力墙震损房屋损伤评估及抗震加固
|
摘要
在完成3层足尺底框配筋砌块短肢砌体剪力墙房屋系统的拟动力子结构抗震性能试验后,模型的梁、板、柱、墙等结构构件均出现了不同程度的损坏。本文详细介绍拟动力抗震性能试验对结构构件造成的损伤,并根据对损伤程度的评估,分别选用粘钢、粘贴玻璃纤维布和裂缝修补技术3种最常用的加固方法对受损部位进行加固,以期获得上述3种方法在地震区对震后受损建筑进行加固或对建筑进行抗震加固时的适用性特征。文中详细介绍上述3种常用加固方法的施工步骤,并按照要求实施加固施工,为研究震后受损结构构件加固后的抗震性能试验研究做准备。
After the systematic substructure pseudo-dynamic test on the full-scale three-floor frame-supported reinforced concrete masonry short-leg shear wall structure,different damage of model element such as beams,plates,columns and walls appeared.This paper introduces the damage caused by the systemic substructure pseudo-dynamic test.Then this paper assesses the damage extent of the whole structural model and formulates the corresponding reinforcement scheme which includes the stick steel,glass fiber reinforced plastic and crack pressure grout gelatin strengthening technology in order to obtain the applicability of the three proposed strengthening technology in the seismic zone.Based on the introduced detailed construction process of the reinforcement scheme,the reinforcement construction on the damaged model is implemented,which prepares for the further seismic performance study on the reinforced model.
