【摘要】 根据约束混凝土的原理,提出一种新型钢管混凝土柱板节点型式,该节点保持了混凝土平板楼盖的连续性,节点区柱钢管不连通,各层楼盖在板柱交接处的板面和板底与钢管混凝土柱连接,通过试验论证了该节点在工程应用上的可行性,并对其传力机理和力学性能进行初步探讨。更多还原

【Abstract】 Based on the principle of restrained concrete, a new-type concrete filled steel tubular colunm-slab joint is presented in this paper. This new-type joint is characterized by keeping the concrete flat plate continuous while making the steel tube of the column discontinuous in the joint core, thus joining the plate and the concrete filled steel tubular (CFST) columns on the top and the bottom of the slab. The feasibility in engineering application of the joint is testified by experiments, and the working mechanism and mechanical properties of the joint are preliminarily studied in this paper.更多还原
