棚式结构大挠曲变形的力学分析

A MECHANICS ANALYSIS TO SHED-STRUCTURE WITH LARGE DEFLECTION DISPLACEMENT

棚式结构是指两短直线边简支另两长曲线边自由的矩底超薄壳面结构,它的变形通常是非线性的,本文对其力学性能进行了分析,导出了有用的结果,并就该结果的应用进行了讨论.

Shed-structure is a thin shell structure with such a boundary condition that is simply-supported at short straight line sides and is free at diagonal long curvilineal sides. Its displacement is usually non-linear. A mechanics analysis is done to this structure and a useful result is derived in this paper. Application of this result is discussed too.
