攻丝钢板高强度螺栓连接的装配式钢框架斜支撑节点受力性能分析
以攻丝钢板高强度螺栓连接的装配式钢框架斜支撑节点静力试验为基础,采用有限元分析方法,对试验过程进行非线性数值模拟与分析。研究了此节点的受力变形机理,探讨了钢材牌号、攻丝钢板厚度、斜支撑钢板厚度、螺栓孔边距、螺栓孔端距、螺栓孔中距等因素对节点受力性能的影响。分析结果表明:随着钢材牌号的增大,节点的抗滑移能力及极限承载力有明显提升,钢材牌号宜选用Q345钢及以上;当攻丝钢板厚度超过20 mm时,其极限承载力不再明显提高,因此攻丝钢板厚度建议取0.7d<sub>0</sub>～1.0d<sub>0</sub>。研究分析的结果可为工程设计提供参考依据。...
