Seismic tests of post-tensioned self-centering building frames with column and slab restraints

Chung-Che CHOU, Jun-Hen CHEN

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 323-334 doi: 10.1007/s11709-011-0119-5

Abstract: When a PT frame deforms laterally, gaps between the beams and columns open.However, the gaps are constrained by the columns and the slab in a real PT self-centering building frameThe method is verified by cyclic tests of a full-scale, two-bay by one-story PT frame.Moreover, a sliding slab is proposed to minimize restraints on the expansion of the PT frame.only minor differences in peak drifts caused by expansion of the PT frame.
