The modified perry - robertson equation is applied to calculate ultimate compressive strength of damaged stiffened panels founded on so - called beam - column method , and the width of effective plate adopts above reduced effective width of a damaged plate 在进行受损加筋板格极限强度计算时,按梁柱法采用修正的perry - robertson方程进行计算,其中有效带板的宽度取板格折减后的有效宽度。
The effective width is not constant along the span of girder , and different point of interest in the span should be selected according to the different structure . for simply supported - span , mid span is selected as the point of interest 对于不同的结构体系应选不同的控制截面,根据结构体系的受力特点对简支梁来说取跨中为控制截面,对连续梁来说取跨中和中间支座为控制截面,而跨中应将边跨和中跨分开。
( 4 ) introducing how to evaluate load capacity pn of wall stud considering post buckling strength of plate element . local buckling effects are determined according to the effective width method used in specifications gb50018 _ 2002 and aisi96 ( 4 )参照gb50018 、 aisi96二本现行规范,采用有效宽度法考虑局部屈曲后强度并对非弹性屈曲应力进行修正,给出了考虑局部屈曲影响和进行非弹性修正后立柱的稳定承载能力p _ n 。
If the gap between two branch members is great , the joint is treated as t - or y - joint . or else , the minimum of the results obtained by the formula based upon steel tube flange shear failure mode and effective width failure mode is adapted for the tension branch joints 给出了矩形钢管混凝土k型节点的间隙判断公式,间隙较大时按t 、 y型节点计算;间隙较小时受拉支管节点承载力按冲剪破坏和有效宽度破坏模式计算,取较小值。
A combination of finite element method and software ansys are adopted to analyse the simple supported - span , the continuous span , the curved simple supported - span and the curved continuous span to provide the practical tables calculating the effective width 鉴于结构体系的复杂性,本文采用有限元分析方法,计算工具则采用ansys有限元分析软件,对直线简支梁、直线连续梁、曲线简支梁和曲线连续梁进行分析,最终得出一套切实有效的有效宽度计算方法。
