［摘要］為了得到采用鋼筋-砂漿面層交叉條帶法加固砌體結(jié)構(gòu)縮尺模型試件的破壞形態(tài)，評(píng)價(jià)其抗震儲(chǔ)備能力，對(duì)經(jīng)歷地震模擬振動(dòng)臺(tái)試驗(yàn)后的模型試件進(jìn)行了擬靜力試驗(yàn)研究，分析了試件的破壞形態(tài)、荷載和位移特征，基于Pushover方法評(píng)價(jià)了試件的抗震能力。結(jié)果表明：試件的破壞模式為窗間墻體交叉條帶附近開(kāi)裂破壞，未形成貫通交叉裂縫，交叉條帶法加固可有效改善窗間墻體的破壞形態(tài)；試件具有較好的變形能力和延性；對(duì)振動(dòng)臺(tái)試驗(yàn)后未破壞的試件采用擬靜力試驗(yàn)方法再次進(jìn)行試驗(yàn)的綜合試驗(yàn)方法是可行的。

Abstract:In order to obtain the failure modes and evaluate the seismic capacity of the specimen of  masonry structure  reinforced by using steel bar-mortar layer crossed strip method, the quasi-static test of the specimen after seismic simulation shaking table test was carried out. The failure modes, load and displacement characteristics of the specimen were analyzed, and the seismic capacity of the specimen was evaluated based on Pushover method. The results show that the failure mode of the specimens is that cracks are formed near the crossed strips between windows but not crossed and through the strips. The crossed strip can effectively improve the failure mode of  the wall between windows.  The specimens have good deformation capacity and ductility.  It is feasible to adopt the quasi-static test method  for undamaged specimens after shaking table test.

Keywords:masonry structure; seismic reinforcement; crossed strip method;  quasi-static test; model test
