•The collapse mechanisms of prestressed precast (PC) concrete structure are revealed according to quasi-static pushdown tests.•PC structure presents a different failure mode compared with cast-in-place reinforcement concrete (RC) structure.•PC structure has a higher collapse resistant capacity, and...
