针对广东商学院图书馆结构所采用的型钢混凝土立柱与斜柱汇交节点，应用有限元分析软件ABAQUS 中的塑性损伤模型，引入恰当的材料本构及损伤因子，模拟节点在实际设计荷载及其在极限轴压承载力作用下的工作状况。通过分析得到节点混凝土应力、钢筋应力、钢管应力的发展规律，根据节点的荷载-位移曲线得出节点的屈服荷载和极限承载力，结果表明：在设计荷载作用下满足结构设计的安全要求，具有一定的安全储备，可为其他类似工程提供参考。
針對廣東商學院圖書館結構所採用的型鋼混凝土立柱與斜柱彙交節點，應用有限元分析軟件ABAQUS 中的塑性損傷模型，引入恰噹的材料本構及損傷因子，模擬節點在實際設計荷載及其在極限軸壓承載力作用下的工作狀況。通過分析得到節點混凝土應力、鋼觔應力、鋼管應力的髮展規律，根據節點的荷載-位移麯線得齣節點的屈服荷載和極限承載力，結果錶明：在設計荷載作用下滿足結構設計的安全要求，具有一定的安全儲備，可為其他類似工程提供參攷。

In this paper,steel reinforced concrete joints in the guang dong college library structure were ana-lyzed by using ABAQUS.In order to simulate the actual working condition of joints,the plastic damage model was used.With the introduction of the proper material constitutive and damage factor,finite element models were established.Concrete stress,steel bar stress,steel tube stress under design loads were obtained.Ac-cording to the load-displacement curve,the yield load and the ultimate bearing capacity were also identified. The safety of this type joints was proved and the strong joint performance goal was realized.
