We doubt whether the monolithic precast concrete structure could be designed as the cast-in-place structure in high seismic\nintensity area. To solve the puzzle, the 1/5 scaled monolithic precast concrete structure model and cast-in-place structure model\nwere designed and tested by shake table. Comparative analysis between them was made to better understand their seismic behavior.\nBased on the experimental results, the failure pattern and mechanism were different, which was concentrated damage in coupling\nbeam and then extended to shear walls of CIPS, and the weak connections presented cracks between precast elements besides the\ndamage coupling beamof MPCS.Thenatural frequency of MPCS possessed a typical feature for theweakness of connections,which\nwas the initial one greater than that of CIPS and decreased fast after the first waves with PGA of 0.035 g. Acceleration amplifying\nfactors presented variation trend under the different earthquake waves. The distribution of seismic response presented linearity\nalong the height of models in plastic stage and turned into nonlinearity later for severe damage. In general, the MPCS and CIPS\nhad similar seismic responses, except typical characteristics. And they were proven to have better seismic performance without\ncollapse under the high-intensity earthquake waves.
