| 摘 要： | 本文研究了空间结构在移动荷载作用下的荷载组合及最不利位置求取的问题.为此,提出了影响面理论.它可以从理论上克服当前空间结构在多个移动荷载作用下不利组合计算时的盲目性.并且编制了绘制影响面透视图的计算机程序.还讨论了荷载组合的简化计算方法.

| Abstract: | In this paper the problem of detrimential position under moving load has been studied.In this connection a theory of influence surface was put forward for the first time.The theory can exactly solve the problems in determine the detrimential position of several moving loads while engineers caculate the stress of space structures (space truss frames,wide span bridges and etc.).The computer program to draw the influence surface in perspective view was programed.The theory of influence surface and method of drawing influence surface are new development in structural mechanics. |
