钢结构住宅的梁柱节点体系比较

Comparative analysis of nodes of beam and column of steel building house

结合钢结构住宅梁柱节点体系的构造特点,分析了内隔板式连接节点体系、带短梁的内隔板式连接节点体系、外肋环板节点体系以及隔板贯通式节点体系这4种主要的节点形式的构造、性能及工程实际应用的优缺点,并对外肋环板节点体系以及隔板贯通式节点体系进行了优化分析.结合工程实践,应用多目标决策方法对4种节点体系的应用效果进行了初步评价,得出了外肋环板节点体系是近期应大力推广的钢结构住宅梁柱节点体系的结论.

Through the comparative analysis of the constitution of four types of beam-column node systems of steel building house including inner-clapboard system,inner-clapboard with short beam system,outer-ring plate system and throughout plate system,this paper summarize the advantages and disadvantages of these four systems.The finite element method has been applied to describe the optimization of the inner-clapboard with short beam system,outer-ring plate system.The multiobjective optimization method is applied to evaluate the effects of the four node systems in the practice of the engineering projects.A conclusion has been drawn that the outer-ring plate node system should be applied extensively nowadays.
