摘要:
基于模态叠加法计算了预制舱在9度抗震设防烈度载荷下的响应谱,建立了预制舱构件变形量对刚度与强度的影响数学模型并计算了预制舱在环境载荷下的形长比。仿真结果表明,预制舱结构满足35 cm积雪、12级台风和9度抗震设防烈度载荷要求,形长比计算结果表明预制舱横向刚度具有优化空间。研究方法可用于复杂框架式结构的强度与刚度计算和评估。
Abstract:
Calculating the response spectrum of the precast chamber under the 9 degree seismic fortification intensity based on the method of modal superposition. It also established the mathematical model of the influence of the structure deformation to the stiffness and strength, and calculated the deformation-length ration for the precast chamber under the environment load. The simulation results show that the precast chamber can fortify the requirement of the environment load of 35 centimeter snow, typhoons of grade 12 and the seismic load of 9 degree fortification intensity. The results of the deformation-length ration show that there is the optimization space of the transverse stiffness of the precast chamber. The research methods can be used to calculate and evaluate the stiffness and strength of the complex frame structure.
