| 摘 要： | 高强钢组合偏心支撑钢框架是一种新型的抗震结构体系,为分析其抗震性能,利用ABAQUS有限元软件建立了简化分析模型。在验证该简化模型合理有效的基础上,建立了某十层算例的整体模型,施加竖向荷载的同时施加水平倒三角形循环荷载作用,进而分析了该算例的滞回性能。研究表明:本文提出的简化分析模型不仅可以较准确的模拟该结构体系的延性和抗侧刚度,还可以有效预测结构的变形分布和非线性性能。

| Abstract: | A high-strength steel composite eccentrically braced frame (HSS-EBF) is a new type of seismic structure system. A simplified HSS-EBF analysis model was established using the ABAQUS software to analyze its seismic performance. The overall model of a 10-story HSS-EBF example was developed after the validity of the simplified analysis model was verified. Subsequently, the hysteretic behavior of this example was analyzed by simultaneously applying vertical load and horizontal inverted triangular cyclic load. The results denoted that the simplified HSS-EBF analysis model can accurately simulate the ductility and lateral stiffness as well as dffectively predict the deformation and nonlinear performance of the HSS-EBF structure. |
