摘　　要：在结构设计中一般重视主次梁的弯矩和剪力，而扭矩往往容易忽略，特别是主次梁相交时，以下三种情况的扭矩要加以注意：１）框架结构中主次梁相交时的边梁承受由于次梁引起的扭矩；２）主梁由两侧次梁跨度相差过大而在主梁中引起的扭矩；３）主梁由两侧不在同一轴线上次梁在主梁中引起的扭矩。commonly pay attention to the bending moment and shear fo rce of main beams and order beams in design,but the torque is easily n eglected,particularly intersect main beams at order beams,pay attentio n to three situations:1)The torque of brim beams which intersect main beams at order beams in frame ,because are effected by order beam;2)th e torque in main beams because of different span of order beams in two sides;3)the torque in main beams because order beams in two sides but not at one axis.
