通过足尺模型的振动台试验,研究轻质复合板(太空板)装配式结构模型的抗震性能及损伤特征,根据其节点连接特点和传力特性,结合北京地区8度抗震设防要求,分别设计了33个工况,并对相应工况进行试验分析。结果表明,在经历了8度小震、中震、大震后结构出现一定的损伤,但未出现明显扭转;整体结构的最大层间位移角能满足规范要求,同时也能满足“小震不坏、中震可修、大震不倒”的抗震性能目标要求。分析结果可为低层轻质复合结构的推广应用提供技术依据。
Based on the vibration table test of full-scale model, the seismic performance and damage characteristics of light weight composite plate (space plate) prefabricated structure model are studied. According to the characteristics of joint connection and force transmission, combined with the requirements of 8 degree seismic fortification in Beijing, 33 conditions, and the corresponding conditions for experimental analysis. The results show that some structural damage occurred after 8 degree of small earthquakes, moderate earthquakes and large earthquakes but no obvious torsion was observed. The maximum inter-story drift angle of the whole structure could meet the requirements of the code and meet the requirements of small earthquakes Not bad, can be repaired in the earthquake, the earthquake does not fall, "the seismic performance of the target requirements. The results of the analysis can provide a technical basis for the popularization and application of low-rise lightweight composite structures.
