Seismic Perfromance On Multi-Storey Precast Buildings (IBS) In Malaysia Subjected To Long-Distant Earthquake Excitation / Nor Hayati Abdul Hamid … [et_al.]

Seismic performance of the reinforced concrete buildings in Malaysia need to examine their structural components under earthquakes excitation. The sub-assemblage of fullscale precast hollow core slabs together with supporting beams are designed, constructed, calibrated and tested under vertical cycl...
