【摘要】 采用两种不同的加固方式,对六片空斗墙进行了试验研究,介绍了试验中对构件的加载控制过程,分析了用HPFL加固后空斗墙在水平低周反复荷载作用下的水平承载能力和延性,比较了不同的加固方案对空斗墙的抗剪承载力、抗震性能、延性等各方面的影响程度.试验证明,采用HPFL加固能显著提高空斗墙的抗震性能.更多还原

【Abstract】 In order to study the lateral-load-carrying capacity and the ductility of the rowlock cavity walls strengthened with HPFL(High Performance Ferrocement Laminate),six pieces of rowlock cavity walls subjected to low-frequency cyclic loads and a constant-amplitude vertical load have been tested.As the strengthening efficiency is influenced by the strengthening method,two different strengthening methods have been introduced so as to compare the strengthening efficiency of different strengthening methods.All the results show that HPFL-strengthening-method is one of effective methods to strengthen masonry structures.更多还原
