不同材料加固农村砌体房屋动力性能分析
|
摘要
为了分析研究农村砌体结构房屋在不同加固形式下的抗震性能,应用ANSYS有限元软件模拟分析打包带与碳纤维两种材料加固农村砌体结构房屋后的整体动力特性改善效果,通过研究结构破坏现象、结构地震加速度响应、极限位移以及应力分布等对两种不同加固形式的砌体结构的抗震性能做出综合评价。研究结果表明:加固后结构的整体性能得到了改善,结构应力分布更均匀,并且结构裂缝呈现多而细的现象,碳纤维加固后结构的地震加速度响应及极限位移最小,打包带加固结构次之,两种不同材料的加固形式明显提高了结构的抗震性能。
In order to acquire the seismic performance of the strengthening rural masonry structure in different forms,by means of ANSYS software simulating and analyzing the dynamic characteristics improvement effect of masonry structure strengthened with packing belt or carbon fiber sheet,the seismic performance of reinforced masonry structure in different forms is evaluated by researching the failure mode of structure,the earthquake acceleration response,the maximum displacement and the stress distribution etc..The research results show that after the masonry structure strengthened,the integrality performance of the structure is improved,the stress distribution is much more uniformity,the number of masonry structural cracks increases,but the width and length of masonry structural cracks change much less.The earthquake acceleration response and limit minimum displacement of rural masonry structure reinforced by carbon fiber sheet are the best,the ones reinforced by packaging tapes are the second,and two kinds of different reinforcement form can obviously improve the seismic behavior of the structure.
