The purpose of this paper was to investigate the mechanical behavior and failure mode of recycled concrete brick masonry wall under cycling in-plane load. These models of masonry walls were constructed in the laboratory and experimented under in-plane cycling load. The masonry wall was made of recycled concrete bricks joined by mortar, with gypsum lining on both faces. A simulation based on the experiment was carried out using the finite element software ANSYS. In the proposed FE model, the recycling concrete bricks and joints were modeled separately, allowing for nonlinear deformation characteristics of the two materials. The results of the experiment and the finite element analysis were analyzed and compared. When the stress distributions were taken into consideration in the experiments and solutions of ANSYS, it was observed that the stress concentration occurred on two diagonals of the masonry wall. The destruction process and characteristics of the masonry wall were obtained by the experiments. The results of finite element method matched experimental results very well. The FE software ANSYS can be used in the analysis of recycling concrete brick masonry walls under in-plane cycling load and strength capacity.

The paper achieved the nonlinear analysis of bearing capacity of recycled concrete filled steel tubular short columns by using finite element analysis software ABAQUS. In order to meet the finite element analysis the writer put forward the modified formula of recycled concrete constitutive relationship of core, and elaborate d the contact at the interface of steel tube and the core concrete and related modeling points. Finally the load-deformation curves of the finite element analysis and test results coincide well. It indicates that the modified formula of recycled concrete constitutive relationship can better meet the requirements of analyzing bearing capacity of recycled concrete filled circular steel tubular columns under compressive Loading by using ABAQUS. Through the simulation experiment, it is useful for us to obtain the ultimate reliable bearing capacity of the similar structure member.

Mechanical testing on the first group of ordinary brick wall-beam and second group of recycled brickbat concrete wall-beam, measured its ultimate load and the maximum deflection, establishing finite element model to analyze, and comparing with the test results. It will be show that under the action of ultimate load, friction coefficient between the upper-wall of the wall-beam and joist can be desirable between 0.35 ~ 0.45, and the friction coefficient of recycled concrete wall-beam is bigger than ordinary wall-beam, and the higher the intensity of the upper-wall is, the bigger its friction coefficient is, as well as the greater stiffness of the wall-beam is.

Considering two-way fluid-structure interaction and using finite element software ANSYS simulation study of cylindrical pier at different flow rates caused by the interaction of the river and pier piers vibration problems, through the discrete solution of wet modal method, and combined with engineering example, the analysis results using Lanczos method extraction, introduction of green's function of point source, using the finite element-boundary element analysis wet modal and wet frequency of the structure. Numerical results show that: Frequencies of wet modal than no fluid medium under the influence of modal frequencies is much lower. So for underwater structures, when analysis the modal,it is must be considered the fluid influence of wet modal.

Research on mechanical property of SFRC was done through experiments of two SFRC T-beams and one concrete T-beam, while the influences of different volume fractions of steel fibers on integral rigidity, ultimate shear capacity, and the crack distribution characteristics were analyzed. ANSYS finite element software was used to simulate the tests and it was found that there was good conformation between the results of ANSYS simulation and tests. The test results and finite element software simulation both showed that the incorporation of steel fibers in the concrete can increase the integral rigidity and ultimate shear capacity, while partially reducing the propagation of cracks effectively. It was also proved that it is reliable to simulate SFRC T-beam by ANSYS software.
