摘要
用ANSYS软件对NIST/AISC研究项目中的UCSD模型进行受力分析,与试验结果进行对比,绘制关键部位的应力图,分析加腋区域的应力分布规律,给出钢框架加腋节点加腋区域应力的新的简化计算方法。
One bare steel specimen that is tested at UCSD is modeled and analyzed using the program ANSYS. The result is compared with the test experimental results of UCSD model.Stress distribution is analyzed.A new simplified model of welded haunch connection is presented.
