SEISMIC RESPONSE OF THE FRAME-BENT STRUCTURE FOR MAIN BUILDING OF A LARGE-SCALE THERMAL POWER PLANT CONSIDERING LATERAL-TORSIONAL COUPLING
-
摘要: 对钢筋混凝土横向框排架、纵向框架 -剪力墙结构的某火力发电厂主厂房进行平扭耦联的地震反应分析 ,研究了该类结构的动力特性、扭转对整体结构受力的影响、层间变形及扭转效应、框架与排架的内力分配等相关内容 ,供设计时参照。Abstract: The seismic response of a large-scale thermal power plants main building with frame-bent in the transverse direction and frame-shear wall in the longitudinal direction, under the peak acceleration 50gal. seismic wave had been researched. The following subjects are concerned:the dynamic properties, the effect of torsion on the structure, the interlayer deformation torsional effect, as well as the internal force distribution of the frame-bent. A simplified calculating method was given.
