| 摘 要： | 圆柱形支撑大跨度建筑稳定性较差,不能在强震冲击下保持稳定的结构状态。为解决此问题,设计圆柱形支撑大跨度建筑结构强震下冲击分析仿真模型,通过圆柱分析法则的确定、有限元支撑模拟分析与监测、圆柱形支撑体系承载能力分析以完成模型的仿真分析与监测。基于此对大跨度建筑结构强震冲击进行静力分析,调整强震冲击下模型的结构,完成模型的搭建。模拟强震冲击环境,设计对比实验结果表明,应用圆柱形支撑大跨度建筑结构强震下冲击分析仿真模型,可明确圆柱形支撑大跨度建筑薄弱点,发现稳定性较差建筑结构单元,达到提升圆柱形支撑大跨度建筑在强震冲击下稳定性的目的。

| Abstract: | Long-span buildings with cylindrical support have poor stability and cannot maintain a stable structural state under strong shock. To solve this problem, this study designs a simulation model for shock analysis of long-span cylindrical support building structures under strong earthquake excitation. Through determining cylindrical analysis rules, analyzing simulations, monitoring finite element support, and performing a bearing capacity analysis of the cylindrical support system, the simulation analysis and monitoring of the model are completed. Consequently, the static analysis of the strong earthquake impact on the long-span building structure is performed, and the structure of the model of a building effected by a strong earthquake is adjusted. Simulation of the strong earthquake impact environment and the experimental results show that the application of analysis and simulation model for large-span cylindrical support building structures effected by a strong earthquake can find the weak points and structural units with poor stability of the long-span cylindrical support structure, thus improving the stability of this kind of buildings effected by of strong earthquakes. |
