摘要
随着巨型框架结构应用的日益增多,主框架梁柱的合理布置成为巨型框架设计的关键问题。以一4跨24层巨型框架结构为例,在保证主框架梁柱总截面面积相等的基础上,改变主框架梁柱的尺寸与数量,采用通用有限元程序SAP 2000,对比分析了巨型框架结构的自振周期、侧移与弯矩;探讨主框架梁柱布置对巨型框架受力性能的影响,提出合理化建议,以指导工程实践。
With the increase in use of mega-frame structures, the main frame beam-column reasonable arrangement becomes the key problem of a design. The results of a 24-story mega-frame structure with 4-span was calculated by the universal finite element program SAP 2000. At the condition of equal total section area of main frame beam-column, changing the size and number Of main frame beam-column, the different structural free vibration periods, structural sways and structural moments were compared, the influence of main frame beam-column arrangement on behaviors of mega frame structures were discussed, and some reasonable suggestions were put forward to guide engineering practice.
