2) double-web shoulder-beam
双腹板肩梁
1.
In this paper,monotonic static loading tests were carried out on four 1/3 scale double-web shoulder-beam specimens with double concrete-filled steel tubular columns used in wide-thick plate workshop project of Baosteel Corporation to study their behaviors of bearing capacity.
虽然可以采取过去的经验公式,但双腹板肩梁的构造和受力都比较复杂,其受力特点和破坏模式是否与单腹板肩梁相同,承载力如何计算,都需要进行深入的试验研究和分析。
3) web
[英][web] [美][wɛb]
梁腹;腹板
6) 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。
