摘要:
提出了一种基于构件截面分层研究的钢-混凝土组合梁柱单元,由于它较准确地考虑了混凝土开裂软化以及钢的应变硬化等材料非线性的影响,同时也考虑了构件各截面的中和轴变化且单元在变形过程中保持了轴向力的平衡,避免了常用梁柱单元受等轴向应变假定的限制,因而放宽了单元划分的要求. 该方法简单有效,易于在计算机上实现,适合于对具有组合构件的结构作整体的极限状态分析.
Abstract:
This paper proposes an efficient,robust and accurate method by layered approach to member’s sectional characteristics allowing for the effects of concrete cracking and steel yielding in composite structure. The member’s moment/displacement matrix is formulated and evaluated by an efficient numerical integration scheme allowing for shift of neutral axis and variation of axial strain along an element, demonstrating the potential scope of application for the developed computer method.
