Study on the Design Method of High Strength Bolts of Extended End-Plate Tensile Connections
摘要
Abstract
The mechanical behavior of high strength bolts of extended end-plate connections are studied by finite element analysis in the paper, and different finite element models are established considering the influence of different end-plate thicknesses and diameters of bolts. The finite element analysis results show that bolt tension is the sum of the tensile force due to moment and the prying force due to the bending deformation of end-plate. The distribution models and calculation formulas of bolt tensions and prying forces for friction type and bearing type high strength bolts are obtained by data fitting of finite element analysis. And the design methods of friction type and bearing type high strength tensile bolts considering the influence of prying force arc given finally.关键词
