Study on Influence of Brace Setting Form on Solid-Web Purline Stable Bearing Capacity
摘要
Abstract
Through the solid -web purline model loading test study and the theoretical analysis under the different braces setting forms, it was indicated that the purline stable bearing capacity suggested in current code, only according to the compression flange number of braces, not taking into account the influence of different braces setting forms is safe, but it is too conservative in some cases. The phenomenon to set the braces in the central of a height of the purline web in a practical engineering is unsafe, which should be avoided using. Through setting the hat shaped pedestal on the both ends of the braces, to realize the braces in the effect of constraining both the up flange and the down flange of a purline in the case to set the braces in the central of the height of a purline web.关键词
