| 摘 要： | 介绍了内构造柱抗震加固砌体墙的方法,采用大型有限元软件ABAQUS6.6,对单调水平荷载下,内构造柱加固墙体的受力性能进行了有限元分析,并将其与外构造柱加固墙体及未加固砌体墙的受力性能进行了对比分析。分析表明,虽然加固后墙体的抗剪承载力提高得并不显著,但加固后墙体的延性系数却显著提高了,其中内构造柱加固墙体延性系数比未加固墙体提高了121.1%,比外构造柱加固墙体提高了26.6%。这种新的加固方法能显著提高砌体墙的抗震性能,具有好的工程应用意义。

| Abstract: | A new seismic strengthening approach,involving the adoption of inside structural columns,is proposed in this paper for the strengthening of unreinforced brickwork masonry walls.Mechanical behaviors of unreinforced brickwork masonry walls strengthened with the new approach,subjected to in-plane lateral monotonic loads,are analyzed using finite element software ABAQUS6.6.The results of the analysis show that the ductility factor of the wall strengthened with the new approach increased by 121.1% and 26.6% comp... |
