平板网架结构选型的探讨

Discussion on the type selection of plate type truss structure

概述了平板型网架选型的原则和可供选择的几种网架结构类型 ,分析了在不同条件下网架结构的受力特点 ,论述了几种不同的支承情况。通过比较和分析不同结构形式在各种支承条件下的优缺点 。

In this paper the principle of plate type truss structure's type selection and several space truss types that can be selected are summarized. Meanwhile the stress characteristics of truss structure under different conditions are analyzed and for some different bearing situations discussion are carried out. Through the comparisons of the advantages and disadvantages of different structural type and different bearing conditions the optimal type is selected.
