Simplified Stiffening of Web-Opening Beams
-
摘要: 介绍了国外钢梁腹板开孔加劲的方式。提出了开孔后强度计算要求,仅水平加劲时加劲肋外伸的长度要求,未加劲时需要进行的宽厚比要求,以及开孔引起的挠度增量计算公式。Abstract: Simple stiffening of web opening in Europe was introduced. Strength check required after web opening was pointed out, the anchorage length of horizontal stiffeners was recommended, the width-to-thickness limit was proposed when the opening was un-stiffended, and equation for incremental deflection due to web opening was put forward.
