本文首先提出并讨论了桁架的网络化方案。接着指出桁架网络的环路分析中若干特点,如杆件刚体位移的作用等,详细推导了问题的解。环路分析是桁架网络分析中必不可少却又长期被忽视者;这样的尝试可认为是全面地进行结构网络分析的准备步骤。
This article first proposed and discussed the truss network solution. Then pointed out some characteristics of the loop analysis of the truss network, such as the role of the rigid body displacement of the rod, and deduced the solution of the problem in detail. Loop analysis is an indispensable but long-neglected truss network analysis; such an attempt can be considered as a preparatory step for comprehensive structural network analysis.
