直交梁钢筋混凝土节点轴压力学性能

摘要

For concrete outer wall under internal leakage, finite element models of empty and full LNG storage tank are established with ADINA software. By inputting El Centro seismic wave, considering the liquid-solid coupling effect, seismic response of LNG tank is processed. The results show that with comparing displacement and acceleration changing curves of empty and full LNG tanks under earthquake, outer wall of tank is effected by liquid of LNG greater. With liquid-solid coupling, its displacement and acceleration all increased compared with empty tank.%本文在合理选取材料的本构模型基础上,利用大型通用有限元软件ABAQUS对直交梁钢筋混凝土节点轴压力学性能进行了计算分析.研究了直交梁端不同约束条件对框架角节点、边节点和中节点力学性能的影响,根据研究结果提出了设计建议.在本文研究基础上,可采用ABAQUS软件对钢筋混凝土节点的轴压力学性能与工作机理进行深入分析,本文的相关结论可供相关研究与工程参考.
