摘要
介绍了由板件和螺栓本身决定的一个高强螺栓的抗拉承载力(纳入了螺栓孔的影响).介绍了钢梁的未加劲外伸端板厚度计算公式,对现行的公式是否能够保证强螺栓、弱端板这样的抗震设计要求进行了判断.对加劲端板节点,介绍了带 1/4 椭圆锥面的塑性机构,由此确定的端板厚度比 GB 51022-2015《门式刚架轻型房屋钢结构技术规定》中的公式确定的值大 4%～10%,对比了未加劲端板与加劲端板的厚度,发现后者基本上是前者的 75%.
Abstract
The tensile capacity of a high-strength bolt,determined by the bolt itself and the steel plate respectively is introduced,the effect of bolt hole is considered.The required thickness of extended unstiffened end-plate is presented,and the weak-end-plate and strong tensile high-strength bolt requirement for seismic design is discussed.A correct plastic mechanism,in which 1/4 elliptical conical plastic surface is included,is used to determine the thickness of stiffened end-plate.The thickness by the new equation is found to be 4～10%thicker than by the equation in GB 51022-2015.The thickness of the stiffened end plate is found to be about 0.75 times the thickness of the unstiffened end plate.
