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.

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.
