摘要:
复杂边界条件的准确模拟是分析Y形钢-型钢混凝土混合柱(Y形S-SRC柱)力学性能的关键。利用整体结构有限元模型提供其在位受力状态,通过单元耦合技术实现了对其的精细模拟,试验结果验证了该方法的正确性。从破坏机制、承载能力和耗能机制方面分析其在位力学行为。结果表明:Y形S-SRC柱的破坏模式为SRC柱上端混凝土压碎; 主要由SRC柱耗散地震能量,塑性变形集中在SRC柱上,Y形钢柱V型口处应力集中明显。
Abstract:
The key to analyze the mechanical behavior of Y-type S-SRC column was the precise simulation of complex boundary conditions.A element coupling technique was used to simulate the in-situ loaded state by the finite element model of whole structure,and the method was verified by experimental results.Furthermore,the in-situ mechanical performances such as damage mechanism,capacity bearing behavior and energy dissipation mechanism were analyzed.Analysis results showed that the failure mode was the concrete crushing on top of SRC columns,seismic energy was dissipated mainly by SRC columns,plastic deformation mostly occurred on SRC columns; and stress concentration was obvious at V-shape location of columns.
