A Fast Computation of Extended End-Plate of Beam-to-Column Connection
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.
