摘要

基于Kelvin碰撞单元和动力弹塑性时程分析,建立了相邻等高七层钢筋混凝土框架模型,从结构层间位移角、楼层剪力和碰撞力这三个方面,研究了在不同防震缝宽度工况下,楼层碰撞破坏对相邻结构响应的影响,探讨了在不同间距下结构碰撞响应的规律,为相邻结构抗震设计和防灾减灾提供合理的建议。
Based on Kelvin collision element and dynamic elastic-plastic time history analysis,the article established a frame model of reinforced concrete adjacent seven-layer,researched the influences of pounding damage on the adjacent structure response under different joint widths of anti-earthquake and the law of structure collision response under different distances from three different aspects of interlayer displacement angle,layer shears and pounding forces.The result can provide some reasonable suggestions for seismic design and prevention and mitigation of disaster.
