摘要
在预应力拱架结构成形过程中结构将产生较大的变位,其施加预应力前后的几何尺寸有很大差异。从工程应用的角度出发,定义了预应力拱架结构受力过程中涉及的工作状态,提出了以施加温度荷载为媒介借助通用软件ANSYS进行找形的方法。运用本文方法可以迅速准确地求解预应力拱架结构的零状态几何和结构的初始态预应力分布,并可保持结构的完整性进行后续的荷载态分析。
This paper provides a further discussion the form-finding method for the stressed-arch structures （STRARCH）,The form- finding method is obtained by using general software-ANSYS which i s Proposed on the basis of exerting temperature load,. Utilizing this method, the corresponding geometryat at the zerostate and the prestress distribution at the initial state can be obtained quickly and accurately. Meanwhile, the integrity of the structure is maintained and the subsequent loading state analysis is carded on.
