摘要:
U 型截面钢拱由三块钢板焊接而成, 可在截面内浇注混凝土形成钢-混组合结构, 从而充分利用底板
钢材的抗拉性能.当作用在拱平面内的荷载达到临界值时, 拱可能出现平面外屈曲即侧倾问题, 而使整个结构
发生平面外失稳.如果U 型截面钢拱沿整个弧线长度上没有隔板, 则会出现两个侧板的局部屈曲.通过建立
有限元计算模型, 讨论了不同参数, 包括截面尺寸, 边界条件, 有无隔板以及隔板间距情况下钢拱的稳定问题,
并对计算结果进行分析, 利用最小二乘法拟合, 得到钢拱平面外稳定承载力的计算公式, 可为工程设计提供参
考依据.
Abstract:
Intro duced in this paper is a new U-section steel ar ch w hich is w elded by three steel pla te s.It can be used as a
sing le sectio n in steel struc ture , as well as a compo site sectio n when concrete cast in hy brid st ruc ture .Arch is the prefer
red struc ture under bearing pre ssure , but fo r certain bending moment , out-o f-plane instability , w hich is also called later
al buckling , in the whole str ucture will o ccur , w hile lo cal buckling in U-shape sectio n may also appear at the same time .
In this paper , tw o kinds of instabilitie s are discussed , and the finite e lement numerical model is built .The parameter analy
sis , such as different sec tion dimensio ns , bo unda ry co nditions, witho ut clapbo ard a long the w ho le str ucture , w ith cla pboa
rds in v ario us space s, is made .Based o n the re sults abo ve , refe rred to the formula of thin-wa ll with o pen slot , bearing
capacity formulas, are pro po sed, which can serv e as a reference in the stability desig n o f steel arch .
