The use of finite element theory and modal analysis theory, the structure of the machine static and dynamic performance analysis and prediction using optimal design method for optimization, the new machine to improve job performance, improve processing accuracy, shorten the development cycle and enhance the competitiveness of products is very important. Selected for three-dimensional CAD modeling software-UG NX4.0 and finite element analysis software-ANSYS to set up the structure of the beam finite element model, and then post on the overall structure of the static and dynamic characteristic analysis, on the basis of optimized static and dynamic performance is more superior double wall structure of the beam. And by changing the wall thickness and the thickness of the inner wall, as well as the reinforcement plate thickness overall sensitivity analysis shows that changes in these three parameters on the dynamic characteristics of post impact. Application of topology optimization methods, determine the optimal structure of the beam ultimately.

Offshore platform rocking wall system and tuned mass damper are briefly introduced, and the paper integrates the advantages of these two kinds of seismic method, and the TMD is attached to the jacket offshore platform - rocking wall system, using the ANSYS for finite element analysis, and the analysis results are optimized. The results show that compared with the offshore platform - rocking wall system, additional TMD can give full play to the performances of the two kinds of seismic methods, which is remarkable.

In order to estimate seismic behavior of LYTAG concrete, the seismic behavior of ordinary concrete have been studied in comparison with LYTAG concrete in this article. At first it discusses the advantages of LYTAG concrete, and then it draws following conclusions through the contrast tests of LYTAG concrete and ordinary concrete and the method of finite element analysis. The seismic performance of Lytag concrete is better than that of ordinary concrete. LYTAG concrete has better social and economic benefits than ordinary concrete from the aspects of seismic fortification.

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2~3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.

Based on the model experiment on seismic behavior of a 1-span, 2-story concrete-filled rectangular steel tubal (CFRST) frame under lateral cyclic loads, a 3-D nonlinear finite element model of concrete-filled rectangular steel tubular frame is proposed in the paper. Compared with the experimental hysteresis curve, the computational results are found to be accurate, which shows that this model proposed in the paper can be applied in structure analysis of concrete-filled rectangular tubular frames. So the model was used in the finite element analysis of concrete-filled rectangular frame with different axial load level. Compared the computational displacement envelop curves, it concludes that the ductility and bearing capacity of CFRST frames reduces with the increasing axial load level.

Polystyrene formwork of lattice concrete wall is a set of lightweight, insulation, sound insulation, fireproof, bearing multi-function in one of the "EPS new energy-saving" wall structure system. Through the polystyrene formwork structure forms of optimized improvement built in construction process of collapse produced high wall plate phenomenon. Do an axial compression ratio of 0.2 lattice specimens of reinforced concrete shear wall in axis pressure and reciprocating level forces test. The damage form of that wall for wall bottom beam-column central cross core ring crack and appear "X" type crack and are crushed. The mesh wall formed strong vertical limb and weak horizontal limb,belongs to the ductility structure , and has more yield , and energy dissipation capacity , and wall overall performance is strong , and avoid brittle failure , and has good ductility、deformation ability and bearing capacity of the characteristics of big .The finite element analysis and experimental results indicated that the ultimate bearing capacity of the wall are the same. For new formworks do wall by finite element analysis, in do not affect its aseismic capacity premise that wall structure forms are optimized design.

A new steel special-shaped lattice column (SSLC) was proposed, which can be used in prefabricated steel structure residence. The finite element models of four SSLC with different cross-section (L-shaped, T1-shaped, T2-shaped and X-shaped) were established under cyclic loading by using ABAQUS, in which the strength, lateral resist capacity and hysteretic behavior were analyzed. The results indicate that SSLC has adequate strength, stiffness and safety redundancy. Among the four SSLC, the SSLC with X-shaped has the best structural performance and seismic behavior.
