打包带加固农村砌体房屋抗震性能分析

了研究打包带加固农村砌体结构房屋的抗震性能，应用ANSYS有限元软件对未加固砌体结构房屋及打包带加固砌体结构房屋进行整体动力特性计算分析。研究结构的地震加速度响应，极限位移，结构的应力分布以及破坏现象等等，由此对打包带加固砌体结构的抗震性能做出综合评价。、研究结果表明：打包带加后固结构的裂缝数量增多．宽度较小．应力分布更均匀，整体性能得到了改善．加固后结构的地震加速度响应较小．极限位移要远远小于未加固结构位移．有效地提高结构的抗震性能。

Analysis on the seismic performance of packing belt reinforcing rural masonry house

By means of ANSYS calculation and analysis the dynamic characteristics of masonry structure and masonry structure strengthened with packing belt housing ,In order to acquire the seismic performance of rural masonry structure reinforce with packing belts,research the structure of the earthquake acceleration response, the maximum displacement, the stress distribution and the structure of the failure mode etc., comprehensive evaluate the strengthened with straps of masonry structure seismic performance. The results show that： after strengthened with packing belt the structure crack number increasing, the width changed smaller, the stress distribution much more unifonmty, the integral performance is improved, the acceleration response to seisnlic and the maximum displacement be ~lr less the structure which not be strengthened, the seismic performance be improved.
