摘    要:根据试验结果和理论分析,确定了钢骨高强混凝土框架边节点抗剪承载力组成中钢骨、高强混凝土、核心区箍筋的具体贡献·确定了在极限状态时的核心区总剪力的计算模型·按照叠加原理认为当达到极限状态时,钢骨、混凝土和核心区箍筋均达到各自的强度设计值,同时考虑了由于高强混凝土的脆性和边节点的约束使得节点强度降低的因素·从而确定了钢骨高强混凝土框架节点承载力的计算公式,通过与试验结果的比较,数据吻合较好·

关 键 词:钢骨  高强混凝土  框架边节点  承载力  节点强度

Abstract:Based on theoretical analysis and test results, how the reinforcing steel, HS concrete and stirrups provide the bearing capacity of the side joint of a steel-reinforced HS concrete frame for shear load is ascertained. A calculating formula or model is developed for the overall shearing force in the core region when it reaches ultimate condition. By superposition method, it is regarded as that the steel, HS concrete and stirrups in core region are all up to their designed strength values when the overall shearing force reaches ultimate conditions, taking the brittleness of HS concrete and restraint of side joint into consideration as they will decrease the strength of joint. The calculating formula is therefore confirmed, of which the result conforms well with the testing result.
Keywords:steel reinforced  high strength concrete  frame side joint  shear capacity  joint strength
