摘要
根据钢框架梁柱外伸端板半刚性连接节点的简化力学模型,通过三个构件试验研究,提出弯矩-转角关系的非线性数学模型,以节点初始转动刚度和极限承载力为模型中的主要参数。给出用组件法计算出的极限抗弯承载力、初始刚度,选用三折线模型将计算结果与试验结果进行比较,验证初始转动刚度和极限承载力计算方法的正确性。
According to the predigestion model of mechanics of the semi-rigid nodes of beam-column end-plate in steel frame, and based on experimental study on 3 different extended end-plate connections, the thesis presented the non-linear mathematics model of the moment-rotation relationship curve with the initial stiffness and ultimate load-bearing capacity for its primary parameter . The thesis gived the ultimate flexural resistance using subassembly method and initial stiffness , and compared with the compution result and experimentation result using three-folden-line model,, validated the calculating method of the initial stiffness and ultimate load-bearing capacity.
