本文介紹了關於交於一點的諸桿件及一組平行桿件的極限荷載的計算法.首先証明近去求桿件系統中極限荷載的計算法——“挨次去掉已屈服的桿件”——是有缺點的,然後依照“桿件系統在具有固定形狀時,所能承担的最大荷載”的概念,拟定山一些討算其極限荷載的法則,其主要的出發點为:(1)先假定各桿皆發揮最大的抵抗外力的性能;(2)再縮減某些桿件的內力,以維持靜力平衡,並使其所能抵抗的外力为最大值,文中不但解決了平面内交於一點諸桿件及平面內一組平行桿件的極限荷載的計算法,而且还討論了空聞中交於一點的諸桿件,及室間中一組平行桿件的極限荷載計算法,
This paper presents the method for calculating the ultimate load of rods and a set of parallel rods that intersect at one point. First, it proves that the ultimate load calculation method for rods and rods in the near-departure system is to remove the yielded rods. “-” is flawed, and then according to the concept of “the maximum load that the rod system can bear when it has a fixed shape,” formulate some rules for the mountain to discuss its ultimate load. Its main starting point is: (1) Assume that all the rods exert their maximum resistance to external forces; (2) Reduce the internal forces of some rods to maintain the static balance, and make the external forces that can resist the maximum force. The calculation of the ultimate load of a parallel member in a plane with a point and a set of parallel members in the plane, and also discusses the members that intersect at one point and the ultimate load of a set of parallel members in the room. Calculation method,
