结合某工程桁架结构拼装顺序选择的实例研究,合理的拼装顺序能够在有限的施工空间内减少临时支撑的措施用量、降低措施成本费用,可以有效减小结构应力和位移。选择桁架结构的拼装顺序时,应根据施工现场的实际条件进行分析,采用几种拼装顺序并进行比较分析,从而寻求最合理的拼装顺序。 Combined with the case study of truss structure assembly sequence selection, a reasonable order of assembly can reduce the amount of temporary support in a limited construction space and reduce the cost of measures, which can effectively reduce the structural stress and displacement. When selecting the truss structure assembly sequence, it should be based on the actual conditions of the construction site analysis, using several assembly sequence and comparative analysis, in order to seek the most reasonable assembly sequence.
