SHERA RESISTANCE BEHAVIOR OF TWO-SIDE CONNECTED STEEL-PLATE SHEAR WALL (SPSW)

The numerical simulation and analysis of shear resistance behavior of two-side connected steel-plate shear wall (SPSW) was carried out by the finite element software ANSYS. In order to investigate the behavior of two-side connected SPSW, a simplified analysis model is brought forward and verified by analyzing the stress characters of a single-span multi-level model under monotonic loads. The forced mechanism and failure mode are investigated. The mechanical behavior of the beams is also discussed in details. It is found that depth-thickness ratio Kand span-depth ratio are the key parameters which influence the shear resistance behavior of two-side connected SPSW; the transfer mode of the horizontal loads is different between two-side connected SPSW and four-side connected SPSW; two-side connected SPSW has no additional moments in columns, which fit the aseismatic principle of/strong column and weak beam0 better; structural measures of the beam connected with the steel plate is demanded when depth-thickness ratio is big, it will guarantee that the damage on the beam occurs latter than the steel plate.
