梁腹;腹板
4) beam web
梁腹板
1.
The computational formula for the local stability of beam webs is based on the assumption of infiniteelastic perfect plates in the former Code for Design of Steel Structures(GBJ1788).
前钢结构设计规范(GBJ17-88)中有关梁腹板局部稳定的计算公式来源于无限弹性完善板假定,一方面与构件的实际工作状况有一定出入,导致计算结果有时会偏于不安全;另一方面又与有关钢梁在弯曲正应力作用下的强度计算公式(考虑截面部分进入塑性)不相协调。
2.
Stability of composite beam web is a very important problem in steel struturedesign.
钢结构组合梁腹板的稳定问题是钢结构设计中应重点考察的内容之一。

6) girder web
钢梁腹板
1.
The theoretical and experimental research on the elasto-plastic buckling strength of the web with longitudinal stiffener in I-section steel girder under pure bending was made using energy method and the influence of stiffness of longitudinal stiffener on buckling coefficient of the girder web was analyzed.
对工字钢梁腹板在纯弯作用下的弹塑性屈曲承载能力进行了理论计算和试验研究，并进行了对比分析，着重研究了纵向加劲肋刚度对腹板屈曲系数的影响－ 对现行《钢结构设计规范》（ＧＢＪ１７ － ８８） 的有关条款进行了讨论
