【摘要】 张拉弦钢拱架结构是一种新型的预应力钢结构体系。本文对张拉弦钢拱架结构从成形到受载的计算分析方法进行研究,推导了该结构双非线性的理论公式,并开发了张拉弦钢拱架结构专用的计算应用程序,通过与国外文献资料的对比,验证了计算方法和计算程序的正确性。更多还原

【Abstract】 The stressed-arch frame is a new type of prestressed steel structure system.In this paper,the analysis method for the stressed-arch frame from form-finding to load computation was researched;the theoretical formula considering geometry nonlinear and material nonlinear was deduced.As a resent,at the same time,the special program for the new structure has been developed,whose correctness is verified by comparison with the foreign research report.更多还原
