摘　　要：结构的找形问题是张拉结构分析中的关键问题。恰当的找形方法能使得结构分析简洁而有效,获得建筑工程师和结构工程师双方的满意。对结构内部应力和结构形态（外形）的控制是结构分析和设计中非常重要的两个方面。本文对目前结构找形的主要方法进行了较为详细回顾与介绍,并对各种方法的优劣作了相应的比较。On tension structures analysis, form finding is one of the key phrases. It is well known that a proper form finding method leads to a concise and efficient structure analysis process, respecting to the designer's ideas. Two aspects, controlling over the internal stress distribution of structures and structures' shape, are the main criterion for evaluating the efficiency of form finding methods. Thanks to the work of others, the general form finding methods are reviewed and introduced, also compared according to distinguishing the advantages and disadvantages of each form finding methods in this article.
