摘要
节点是结构受力的关键部位,深入了解和研究其在火灾下的力学性能至关重要。采用有限元软件ABAQUS建立火灾作用下节点的温度分布和受力性能的分析模型,理论计算结果得到试验结果的初步验证。利用理论模型,初步分析了火灾作用下梁柱节点温度场及其力学性能的变化规律。
The joint is a key forced position of a structure, so it is extremely important to understand and research mechanical behaviors of joint in fire.Analytic model of temperature distribution and forced behavior of the joint in fire is set up using ABAQUS software.The theorectical results are verified initially by the test results.Using this model, it is analyzed that the changing law of temperature field and the mechanical behaviors of a beam-column connection in fire.
