边界条件对扁球壳内力的影响分析

ANALYSIS OF EFFECT OF BOUNDARY CONDITION ON INTERNAL FORCES OF SHALLOW SPHERICAL SHELLS

基于一对边简支扁球壳有矩理论解析解，考虑多波连续扁球壳在连续边界的内力与位移协调，研究多波连续扁球壳的内力分布规律，分析工程中常用的假定连续支座为固定支座的计算方法的误差，确定简化方法的适用范围。

Based on the moment theoretical analytic solutions of shallow spherical shells with two opposite edges simply supported,considering the coordination between the internal forces and deformations of the continuing boundary of multilateral span shallow spherical shells,the internal forces distribution pattern of the multilateral span shallow spherical shells is studied,the calculating error in general engineering calulating method considering continuing boundary as fixed supprort is analysed and the applicable limits of the simple method is determined.
