摘要
由于传统抗震分析方法在住宅建筑的抗震分析中,具有较低的振型刚度,为了提高住宅建筑抗震分析的振型刚度,提出了混凝土框架结构施工技术在住宅建筑的抗震分析。采用混凝土框架结构施工技术将住宅建筑的破坏状态限制在一个目标水平内,完成抗震性能分析目标的选取;然后利用建模分析得到载荷-位移曲线,并计算了住宅建筑中各个构件的刚度,根据曲线之间的转换,完成了Pushover分析模型的建立;通过地震的时程分析来实现住宅建筑的抗震分析。实验结果显示,基于混凝土框架结构施工技术的住宅建筑抗震分析方法相比于传统抗震分析方法 ,住宅建筑抗震分析的振型刚度值提升了39.29%。
Since the traditional seismic analysis method has relatively low vibration mode stiffness in the seismic analysis of residential buildings,in order to improve the mode stiffness of seismic analysis of residential buildings,the seismic analysis of concrete frame structure construction technology in residential buildings is put forward.The paper uses the concrete frame structure construction technology to limit the damage state of residential buildings to a target level,and complete the selection of seismic performance analysis objectives;then the paper uses modeling analysis to obtain the load-displacement curve,calculates the stiffness of each component in the residential building,and completes the establishment of the pushover analysis model according to the conversion between the curves;seismic analysis of residential buildings is achieved through time-history analysis of earthquakes.Experimental results show that compared with the traditional seismic analysis method,the seismic analysis method of residential buildings based on the construction technology of concrete frame structure,the vibration mode stiffness value of the seismic analysis of residential buildings has increased by 39.29%.
