【摘要】 巨型结构体系是一种超常规的具有巨大抗推刚度及整体工作性能的大型结构体系,主次结构受力明确,布置灵活,可满足特殊的建筑形式和建筑功能的要求,特别适合于在大型复杂的高层与超高层建筑中应用。论文采用非线性有限元方法,研究了巨型钢框架结构和大型支撑钢框筒结构的静、动力工作性能;进行了巨型钢柱成比例加载的空间滞回性能的试验研究;开展了开洞高层建筑刚性模型的风洞试验;介绍了研究成果在实际工程中的应用。最后提出了应进一步研究的若干关键问题。更多还原

【Abstract】 Mega structures have great lateral stiffness and excellent overall performance, with which designer can enjoy flexibility in structural layout of plain and elevation and satisfy the requirements of various service function. With the nonlinear FEA method, the static and dynamic characteristics of mega steel frame structures and mega truss structures are studied. The test of spatial hysteresis behavior for mega steel columns is carried out and the wind tunnel tests on wind pressure distributions of rigid models of mega structures are conducted. At last the applications of the research achievements are introduced, and some problems needed to be studied in future are put forward.更多还原
