【摘要】 针对低烈度区砌体结构房屋抗震的需要,本文提出利用纤维砂浆带加固砌体墙的一种廉价抗震方案。运用有限元分析软件Ansys10.0进行数值模拟分析,探讨这种加固方案的可行性,并在此基础上进行试验研究。通过纤维砂浆带加固砌体墙片在低周反复荷载作用下的试验,对墙片的破坏特征、裂缝的发展过程、滞回特性、结构延性等技术指标进行对比分析,结果表明,采用纤维砂浆带加固砌体墙有助于提高墙体的开裂荷载,增加结构的延性,改善墙体的抗震性能。更多还原

【Abstract】 Aiming at seismic requirement of masonry structures in region with low seismic intensity,this paper proposes a seismic measure at a low price that uses fiber reinforced mortar(FRM) to reinforce masonry structures.Taking the advantage of finite element analysis software Ansys10.0 and discussing the feasibility of this method,on the basis of finite element analysis,the authors conducts experimental investigation.Though the test of masonry structures reinforced by cement mortar,under cyclic lateral loading,the authors compare the character and development in crack,hysteretic behavior,and structural ductility.Test results show that the masonry structure reinforced by cement mortar can increase the structural cracking load,structural ductility and improve the aseismatic behavior of walls.更多还原
