本文将杆系结构的塑性破坏荷载用塑性弯矩系数及外功系数来表达,讨论了机构相互组合时的规律性,运用这些规则为求得任何复杂的杆系结构的型性破坏型式及破坏荷载提供了方便的途径,避免了在分析中需要凭经验试算的缺点。
In this paper, the plastic failure load of the rod structure is expressed by the plastic moment factor and the external work coefficient. The regularity of the combination of the mechanisms is discussed. These rules are used to obtain the complex damage type and the failure load of any complex rod structure. Provides a convenient way to avoid the disadvantages of empirical trials in the analysis.
