Shaking table test of a novel buckling restrained multi stiffened low yield point steel plate shear wall
Abstract We proposed a novel buckling restrained multi stiffened low yield point steel plate shear wall (BR LYP SPSW) To study the seismic behavior of BR LYP SPSW, a 1:3 scale model shaking table test was conducted. The increase in the peak ground acceleration decreased the natural frequency and acceleration dynamic magnification factor and increased the damping ratio. The advantage of the sandwiched LYP infill plate is the higher order buckling formed at the LYP infill plate, which played an important role in "the first line of defense." The maximum inter storey drifts during frequent and rare earthquakes were 1/694 and 1/88, respectively, which met the demands of the seismic design code of buildings.
