Non-linear test of precast subframe subjected to cyclic lateral loadings

The demand for new building has been increased significantly, which can sustain loads whether lateral loads as well as gravity load. So far concrete has proven its reliability on most of structural system but it has a big drawback which is the slow construction rate. To eliminate this issue precast...
