| 摘 要： | 为全面探讨梁柱节点的受力性能与变形特性,进行了蜂窝状钢骨混凝土十字形柱-钢梁节点的单调加载试验研究和有限元分析,重点考察典型强、弱节点的承载能力、破坏形态以及轴压比、配箍率等主要参数对节点承载力的影响。结果表明:影响强节点承载力的主要因素是钢梁尺寸和钢材强度,影响弱节点承载力的主要因素是混凝土强度、节点区型钢腹板强度和高厚比。

| Abstract: | The monotonous loading tests and finite element analysis of the honeycomb steel reinforced concrete(SRC) cross-shaped column-steel beam joints were made to discuss the loading and deformation characteristics of strong joints and weak joints.Then,the influences of main factors,such as typical strong and weak nodes bearing capacity,failure mode,axial compression ratio,reinforcement ratio,and so on,were investigated.Some suggestions for the practical design were given.Results showed that the main influence factors on the behavior of strong joints were the size of the steel beam and the steel strength.The main influence factors on weak joints were concrete strength,the strength of the steel-web and the height-thickness ratio. |
