Restrained Torsion of Open Thin-Walled Bar with Batten Plates
摘要
Abstract
Based on the consistency theory of restrained torsion,Vlasov' s rigid-frame assumption and Kollbrunner-Hajdin' s longitudinal warping displacement assumption,with the bending and shear deformation of batten plates,the total potential energy of open thin-walled bar with batten plates and corresponding Lagrange function are obtained.By dual variables,a Hamiltonian dual system for the reinforced open thin-walled bar with batten plates is constituted.High accuracy numerical solutions can be obtained by a precise integration method of two end boundaries.This method has high precision.The calculating process is simple and clear.A new way of restrained torsional analysis of reinforced open thin-walled bar with batten plates is provided.关键词
