天津近代典型砖木结构建筑基于安全鉴定的抗震性能评价
|
摘要
针对天津近代老旧建筑,尤其是砖木结构房屋开展了大量的安全鉴定和实际检测工作。获取了一栋近代典型砖木结构建筑的结构尺寸,检测了承重主体的强度,查明了结构的安全隐患,分析了结构的抗震性能,给出了抗震加固的建议措施,对全国近代典型砖木结构的安全鉴定和抗震加固具有一定的指导意义。
Considering the older buildings in Tianjin that have survived to modern times, particularly the brick and wood structure, considerable safety assessments and actual inspection work were carried out in this paper. The structural dimensions of a typical brick and wood building in modern times were obtained, and the strength of the load-bearing body was tested. The hidden risks of the structures were identified, and the seismic performance of the structure was analyzed. Finally, suggestions and measures for seismic reinforcement of such buildings are given. This study offers guiding in the safety assessment and seismic reinforcement of typical modern brick and wood structures.
