A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested in Japan at the Building Research Institute (BRI), full-scale exterior and interior subassemblages tested at The University of Texas at Austin, and 1/12. 5 scale tests at Stanford University provide a vehicle for making an evaluation of the role of the slab in complete structures as well as in subassemblages. The objective of this paper is to provide an indication of slab participation in the lateral load resistance of moment resisting frames.
