[摘要]首先進行了試件鋼材的基本力學材性試驗,測量試件鋼梁板件平整度方面的初始幾何缺陷;在

此基礎(chǔ)上展開主體試驗,主要分析和對比設(shè)與不設(shè)斜向加勁肋、設(shè)有不同方向斜向加勁肋的H型鋼梁破壞

過程,研究斜向加勁肋對鋼梁極限承載力的影響和更有效的設(shè)置方式。

Abstract: Based on the specimen′s basic mechanical properties test result and the measured data about the initial geometric imperfections of the beam′s plate planeness, the main experiment was revolved around the analysis and contrast on the destruction process of H-shaped steel beam with or without web′s oblique stiffener, or with web′s oblique stiffener in different direction, with the research of the impact of stiffening its web with oblique stiffener on its ultimate bearing capacity, then to find the more effective setting mode.

Keywords: oblique stiffener; experiment study; H-shaped steel beam; ultimate bearing capacity
