新型钢管混凝土柱节点的试验研究

Experimental Research on a New Type of Steel Tube Confined Concrete Column Joint

本文提出了一种新型的钢管混凝土柱节点，并进行了模型和原型静载试验。文中详细介绍了试验方案的设计、试件的制作、加荷方式、试件的裂缝发展情况及破坏形态等试验结果。试验研究表明，钢筋混凝土环梁节点的基本构思在概念上是正确的，在实际上是可行的。

A new type of reinforced concrete beam and steel tube confined concrete column joint is presented in this paper, and the static experiments of model and prototype of the joint have been carriedout. Design of experiment scheme, preparation of specimens, loading methods, development ofcracks in specimens, and their failure behavior are illustrated in detail. Results of experiments showthat the reinforced concrete ring beam joint is correct in concept and feasible in practice.
