带隅撑钢框架在风荷载作用下的变形分析

Analysis on the Sway-resisting Capacity of the Kneebrace Steel Frame Under the Wind Load

通过建立多高层隅撑钢框架有限元模型,对其进行在风荷载作用下的抗侧移能力的有限元分析,并与纯框架进行总位移和层间位移的对比分析,研究隅撑钢框架结构体系的抗侧移性能及抗震性能。通过有限元计算得出带隅撑钢框架结构与钢结构的层间位移与总位移,隅撑钢框架结构与钢框架结构相比有良好的抗侧移性能,其层间位移与总位移相应减少50%左右。

The researches of the sway-resisting capabilities of the kneebrace steel frame structure.establish the overall three-dimensional model of the kneebrace steel frame,carried out in the wind load capacity of the sway-resisting of the finite element simulation analysis,comparative analysis on kneebrace steel frame and steel frame for displacement and displacement between stories.Calculated the displacement and displacement between stories of kneebrace steel frame,research on the mechanism of force of kneebrace steel frame under the control of lateral cyclic load.Research find that kneebrace steel frame has strong capabilities of sway-resisting,its story drift with a corresponding reduction in the total displacement of about 50% to steel frame.
