Dynamic Analyses Of Kant Beams Using Weak Form Differential Quadrature Method Under Traffic Load

With its unique advantages,the composite beam structure has been widely used,which makes the analysis of the structure of composite beams increasingly demanding.The high beam theory plays an important role in the design and analysis of the composite beam structure,but the conventional Euler-bernoulli beam,Timoshenko beam and Reddy beam and Levinson generally ignore the transverse extrusion deformation of the beam.Is adopted in this paper,for the weak weak points quadrature element method(WQEM)on at the same time considering the axial and lateral deformation of Kant Gao Jieliang to static load model and the related analysis under moving load,so as to its attention and provide reference for engineering design and application value.First of all,the first two chapters summarize the application principle of the integrative element method in the development background and the mechanical analysis of the composite beam in the engineering application.Then,according to Kant Gao Jieliang theory and the static analysis of the principle of virtual work,the finite element static analysis of the finite element discrete equation and weak weak points quadrature yuan discrete equations,and carries on the correlation analysis of the static problem.Finally,by Kant beam model for the straton beam in composite beam characterization and the finite element dynamic analysis of the principle of virtual work,established the finite element dynamic analysis of finite element discrete equation and discrete equations,weak weak points quadrature yuan compiled the related computer program,and studied the dynamic response of a composite beam under the traffic load.In addition,the corresponding program is using computer compared with other literature data,proved in this paper,the correctness of the model of Kant and weak weak points quadrature element method in structural mechanics analysis of the superiority,in order to provide some reference value for the structural design problem in the actual project.
