2种不同刚度模型下框架结构扭转性能分析
|
摘要
基于传统框架结构扭转近似计算中,框架柱抗侧刚度是采用D值法计算的,其计算较复杂、烦琐,为简化计算,引用Smith & Coull法计算框架柱抗侧刚度。为保证计算方法可靠,对框架结构算例在这2种刚度计算模型下得出的扭转性能进行对比分析。研究结果表明,在2种刚度计算模型基础上得到的框架结构总扭转角、层间相对扭转角、楼层剪力等扭转性能结果非常相近,而Smith & Coull法较D值法计算更为简便,故在框架结构的扭转近似计算中可优先选用。
Based on the fact that in the proximate calculation of torsion effect of the traditional frame structures,the column push-resistant stiffness is calculated by D value method which is more complex and difficult. The Smith & Coull method was proposed to make the calculation easier. To ensure the reliability of the calculated method,torsion performances in frame structure is contrasted with the two stiffness models. The torsion performance results such as the total angel of torsion on the basis of two stiffness model are close to each other,and Smith & Coull method is simpler which has the priority in the proximate calculation of torsion effect of the frame structures.
