In recent years , with the production of homemade h - section steel members , the above - mentioned factors have been well improved 近年来,随着国产热轧h型钢投入生产后,情况得到了改善。
Wp = 6 > the practical table is compiled that integral stability coefficient of homemade rolled h - section steel beam under constant moment 编制了等端弯矩作用下轧制h型钢梁式构件的整体稳定系数表,可供工程设计参考。
The suggestion is put forward that adopting the different geometry control condition between rolled h - section steel beam and general i - section steel beam 本文提出轧制h型钢的几何控制条件,并建议将一般工字形截面简支梁和轧制h型钢梁分列处理。
Based on the gb50017 code , the geometry control condition of integral stability capacity of homemade rolled h - section steel beam is conservative excessively and is modified accordingly 本文得出精度更高、适用范围更广的计算简化式。 gb50017关于梁的整体稳定几何控制条件对国产轧制h型钢过于保守。
