SYMMETRIC DESTABILIZING CRITICAL LOAD FOR A CIRCULAR ARCH WITH FIXED SUPPORTS UNDER VERTIC AL DISTRIBUTIVE LOAD
-
摘要: 按 Ritz 法求得在垂直分布荷载go/cos2θ作用下具有足够工程精度的固支圆拱正对称失稳临界力的近似值，得到了一些可供参考的结果.Abstract: With sufficient precision, the approximate symmetrical destabilizing critical load for the circular arch with fixed supports are calculated by Ritz method.
