农村典型砖砌体结构房屋抗震性能试验研究
|
摘要
为了解北京地区农村砖砌体结构住宅的抗震能力,本文选取了一种典型的砖木结构房屋作为研究对象,该类房屋以砖垛作为前檐支撑柱,屋架采用木构件,围护结构采用砖墙砌筑。振动台试验模型采用2/3缩尺设计,并按照北京地区8度抗震设防的要求,分别进行了小震(0.072g)、中震(0.2g)和大震(0.4g)条件下的振动台试验。通过分析试验后的结构破坏现象和相关参数,得出了试验模型的抗震性能。基于试验的破坏现象提出了北京地区农村此类建筑相应的抗震加固原则。
In order to investigate the seismic resistant capacity of typical brick structures in Beijing rural area,a 2 /3 scaled typical brick-timber structure model with brick columns,wood roof and brick peripheral walls was designed and tested on a shaking table,which is a single story brick-timber structure with three bays.According to the national seismic design code GB50011,seismic fortification intensity is 8 for most rural areas in Beijing.Different dynamic base excitation levels,such as design small earthquake with PGA = 0.072g,design moderate earthquake with PGA = 0.2g and great earthquake with PGA = 0.4g respectively,were input to the model.By analyzing the dynamic responses and cracking characteristics on the brick walls after testing.the seismic resistant capacity of the model was obtained.Some key technologies on how to strengthen and retrofit the existing rural brick-timber structures in Beijing were pointed out.
