推导了考虑水平和垂直位移时空腹桁架连续代入法的计算公式.同时,结合本文的算例和分析,对空腹桁架的设计提出了一些合理建议. The calculation formulas of continuous truss truss successive substitution method considering horizontal and vertical displacements are deduced. At the same time, combining with the examples and analysis of this paper, some reasonable suggestions are put forward for the design of truss trusses.
