摘　　要：采用目前方法对复杂建筑空间结构节点连接进行设计时,没有对空间结构节点的可靠性进行分析,导致方法存在可靠度低、收敛速度慢、失效概率高和最大应力小的问题。提出基于可靠度的复杂建筑空间结构节点连接方法,首先通过细菌觅食优化算法分析复杂建筑空间中结构节点的可靠性,根据分析结果选取可靠性高的空间结构节点进行连接设计,在此基础上构建复杂建筑空间结构节点的连接优化模型,利用模型完成空间结构节点的连接设计。仿真结果表明,所提方法的可靠度高、收敛速度快、失效概率低、最大应力高。When some methods were used to design the node connection of complex space structure in buildings,the reliability of node was not analyzed,leading to low reliability,slow convergence,high failure probability and small maximum stress.Therefore,a method of connect nodes in complex space structure of buildings based on reliability was presented.Firstly,the bacterial foraging optimization algorithm was used to analyze the reliability of nodes in complex space structure of buildings,and then the nodes with high reliability were selected for connection design.On this basis,an optimization model was built for these nodes.Finally,this model was used to design the node connection.Simulation results show that the proposed method has high reliability,fast convergence speed,low failure probability and high maximum stress.
