【摘要】 本文主要研究了张拉式索膜结构的找形问题。具体的工作如下：(1)在查阅大量文献的基础上，对张拉式索膜结构的历史、现状和它的发展作了比较详细的论述，认真分析了国内在索膜结构设计和计算上的现状。(2)对应用国际上比较流行的力密度法对索膜结构进行找形分析的问题进行了一系列的理论推导，得出了相关的公式。(3)对应用力密度法找形的基本公式进行了一系列的等价变换，得出了更加适合于程序编制的结果。并且，根据理论推导的结果，应用Digital Visual FORTRAN 5.0编制了对索膜结构进行找形分析的力密度法计算程序。(4)对几个比较典型的张拉式索膜结构进行了详细的算例分析，并且将找形结果的数据文件用第三方程序Gedein.exe显示出了图形。算例分析的结果表明了本文所编制的程序的正确性和实用性。更多还原

【Abstract】 In this thesis, the form-finding analysis of tensile cable-membrane structures is studied primarily. The emphases are put upon as follows:(1) Under the ground of plentiful documentation, the history, the current situation and the development of the tensile cable-membrane structure are examined, and the current situation of domestic engineers when designing and calculating it is considered in detail.(2) The theory of the form-finding analysis of the cable-membrane structure with the force density method is deduced explicitly and corresponding formulae are obtained.(3) Based on the formulae obtained above, a series of theoretically equivalent form transformation is done, and the results which are more suit for programming are acquired. According to that, the calculation program of the form-finding analysis of cable-membrane structures using the force density method is composed on the platform of Digital Visual FORTRAN 5.0.(4) The detailed example analyses are done. on several typical tensile cable-membrane structures, and the corresponding result data are shown as figures by using the data-processing software-Gedein.exe. The consequence of the example analyses proves the correctness and the usefulness of the program given by this paper.更多还原
