摘要
巨型框架结构又被称为主、次框架结构，其独特的两级受力体系不仅有利于提高结构整体性，改善结构安全性能，减少材料用量和工程造价，亦给建筑设计带来了更大的灵活性，因此在超高层建筑中正得到越来越广泛的应用。本文结合对采用巨型框架结构体系的南京多媒体通讯大楼 1∶ 25微粒混凝土模型的模拟地震振动台试验的分析和探讨，着重研究了巨型框架结构的动力特性、弹性和弹塑性地震反应及结构的破坏形式。
Mega- frame structures are also known as Major- sub- frame structures. The particular two- levers support system of mega- frame is not only helpful to increase integrity of the structures, improve structural safety properties, economize material and engineering cost, but also bring more flexibility for building design. So mega- frame structures have more and more extensive application in skyscrapers in recent years. According to the shaking table experiment of Nanjing Multimedia Communication Building which adopted a mega- frame structure system, this paper studied the dynamic characteristics, the seismic responses in elastic and elastoplastic phases, and the destructive form of the mega- frame structure.
