CALCULATION OF STEEL-PIPE COLUMN BASE CONNECTION UNDER A COMBINATION LOADING OF COMPRESSION,SHEAR AND TWISTING
-
摘要: 对于户外广告牌和交通标志,经常采用F型单肢钢管柱。由于风载荷是控制载荷,柱脚受力为偏心受压,偏心受剪,承受很大的双轴弯矩和水平扭矩,底板与锚栓的设计计算与一般型钢柱有所不同,柱脚弯矩对其抗剪承载能力有很大提高,计算时应考虑其影响。Abstract: F-type steel-pipe column is often used for outdoor advertisement board and traffic sign.The wind load is the control load.The column base is under eccentric compression and shearing force.The bending moments of two axial directions and the twisting moment are large.Based on classical methods a design and calculation procedure are proposed for the base-plate and anchor bolts of steel-pipe column base connections, which is different from that of the profile steel column base.
