H型钢柱高强螺栓拼接设计方法探讨

Design Method Research of High Strength Bolt-splicing Joints of H-shaped Steel Columns

依据现行新规范,给出按等强度设计原则H型钢柱高强螺栓拼接连接设计计算,并与现行2010版STS钢结构CAD软件计算结果进行比较.采用本文依据现行新规计算:柱翼缘螺栓受剪承载力、腹板螺栓受剪承载力较大,说明现行新规范规定的技术条件较严格;设计计算为工程设计中H型钢柱高强螺栓拼接连接提供设计参考.

According to new design codes,the design method of high strength bolt- splicing joints for H- shaped steel columns as researched. The design results with this method were compared with those by the STS software. The shearing forces calculated by this method of the flange bolts and the web- plate bolts were stronger. This showed the technical requirements in now code are more strict; and this design method is available and usable. This will offer reference for actual project designs for the high strength bolt- splicing joints for H- shaped steel col- umns.
