砌体结构房屋抗震性能评价与加固对策

Seismic behavior appraisements and strengthening strategies of masonry buildings

针对目前我国现有砌体结构房屋建造年代不一、抗震设防标准不同和建造质量参差不齐的实际状况 ,在进行了大量的调查研究之后 ,选取了一幢具有代表性的房屋 ,依据现行建筑抗震鉴定标准和建筑抗震设计规范 ,按照不同的地震参数 ,用PKPM软件进行计算分析 ,对其抗震性能进行评价 ,得出抗震鉴定结论 .然后由点及面地分析了该类房屋在结构抗震设计方面普遍存在的问题 ,并在此基础之上 ,对加固策略做了初步的探讨 ,提出了看法和建议 .

Masonry buildings have different construction ages, seismic fortification criterions and qualities at present in China. After a lot of investigations were done,a typical building was calculated and analyzed by PKPM which is a popular program of architecture and structure design for buildings in China according to different design parameters of ground motion. During the course, standard for seismic appraisements of building and code for seismic design of buildings were referenced. Then appraisements of seismic behavior for this building were given. A series of problems which are general in seismic design of masonry were analyzed. The strengthening strategies were also discussed. Finally, some suggestions for masonry structures were put forward.
