Abstract:
It is presently unclear whether the reinforced concrete flat-slab connection possesses sufficient lateral displacement capacity to survive the lateral deformations that can be expected during a strong earthquake. The objective of this paper is to examine the available data from present and past research and from that develop an understanding of the major parameters that influence the lateral displacement capacity and ductility of reinforced concrete flat plates. The significant effects of gravity load and biaxial lateral loading are presented together with the implications of the findings with regard to seismic design and performance. It is recommended that to insure adequate displacement ductility under extreme earthquake loading, the gravity level shear acting on the slab critical section be limited to 1.5ûf'c psi.
