Elastic Finite Element Analysis Of Deep Beam And Frame-shear Wall

In this thesis, the chief content is to carry on the elastic analysis about deep beams and frame-shear wall using truss model and the finite element program which is edited by author.Firstly, the paper deduced quadrangular 4-node isoparametric element of element stiffness matrix and established analysis procedure of correspond finite element. If the calculated results can tally well with those from Program ANSYS that it proved the finite element program is correct and feasible.Secondly, the paper used the procedure which is edited by author to carry on the elastic analysis about single-span simple supported deep beams, two-span continuous deep beams and single-span simple supported beam deep with web opening. And under the vertical uniformly distributed load, the procedure located exactly on truss model separately. In addition, the post processor and the post processor which is made by the author played the very major role. The former can check the correct of the model, such as element node diagram, load diagram; the latter can provide a lot of convenience for data-processing, such as the deformation diagram, the principal stress diagram, the normal stress distribution of the mid-span section, and truss model diagram.Finally, the paper analyzed single-span and two-span frame-shear wall under the vertical uniformly distributed load using the finite element analysis program of the quadrangular 4-node isoparametric element and the beam element; and it also analyzed the influencing factor on the composition of pull forces at the bottom of the shear wall, such as the high of loads and the boundary conditions; and it showed the influence on frame-shear wall which made of uneven settlement leading to internal force. In addition, the post-processing program can also plot the normal force diagram, the shearing force diagram and the bending moment diagram of the frame beam and column.
