摘　　要：火电厂主厂房通常仅在纵向设置剪力墙,而在进行0.2Q0调整时,设计程序是将所有与框架柱相连的梁内力都进行调整,因此夸大了横向梁截面的内力,造成不必要的保守。建议对于在纵向设置剪力墙的主厂房进行两次设计计算:先按框架剪力墙结构进行第一次设计,然后按框架结构进行第二次设计,横向框架梁截面以第二次设计结果为准,其余构件以第一次设计结果为准。The main building for a thermal power plant usually has shear wall only in longitudinal direction, and in 0.2 Qo adjustment, the design software always adjust section internal forces of all the beams connected with the frame column, which exaggerates section internal forces of lateral beams, causing unnecessary conservativeness. It is proposed twice design calculation should be done for this kind of structure. In the first step, the structure is designed according to frame-shear wall system. Then the second step calculation and design are carried out, in this case the structure is designed being as frame system. It is suggested to use the calculation results from second and first step design for lateral frame beams and the other components respectively.
