梁柱铰接节点细部设计中的撬力验算

PRYING FORCE CHECKUP IN HINGED JOINTS DETAIL DESIGN OF BEAM AND COLUMN

介绍了美国《钢结构设计规范容许应力法》第9版(AISC-ASD-9thEdition)中撬力验算在梁柱铰接节点细部设计中的应用。通过建立力学模型,进一步分析了撬力作用对高强螺栓抗剪承载力的影响及计算方法。

It is introduced that the application of prying force checkup to the design of hinged joint details of beams and columns in＂American Institute of Steel Construction： Manual of Steel Construction Allowable Stress Design, Ninth Edition＂（AISC-ASD-9th Edition）, The effect of the prying force on shear bearing capacity of high-strength bolts, and its calculation method are analyzed further by setting up mechanical models.
