大型钢筋砼受弯构件附加型钢的受力性能研究

RESEARCH ON THE BEHAVIOR OF LARGE BENDING COMPONENTS OF STEEL-ATTACHED REINFORCED CONCRETE

本文以建造中的浦东正大商业广场作为工程依托，按1：3缩尺比例对两个SRC梁—RC柱十字节点试件进行了梁端低周反复加载试验，试验参数为不同型钢端部锚固型式。分析与对比了这种节点构造方式的强度、延性与耗能能力，并提出了实用承载力计算公式，为工程设计与施工提供了科学依据。

In this paper,on the basis of Zhengda Business Plaza project being constructed in Pudong,slow-cycle loading experiments on two cross-joint members of SRC beam and RC column have carried out. The ex-perimental parameters are the anchorage and steel type. The strength,ductility and energy dissipation capacity are analyzed and compared in terms of the experimental results. A practical computation formula of ultimate load-bearing capacity is proposed for the design and construction of projects.
