Abstract:

The objective of this study was to investigate the seismic force resisting mechanisms of structural walls considering the interaction with the foundation beam, ground floor slabs and piles that supported the walls. Experimental tests were conducted on two 15% scale sub-assemblage specimens of the bottom three stories of a twenty-story structural wall. The structural walls were of monolithic construction for one specimen and of precast shear wall construction for the other. Cyclic lateral loads were applied with proportionally varying vertical loads to simulate loading conditions for the twenty-story prototype building. Conclusions were drawn concerning the deformation capacity and the strength deterioration after maximum strength shown by the walls. Contrary to the design, the yielding of the shear wall preceded the yielding of the foundation beam. Flexure-shear cracks of the shear wall penetrated the slabs transversely and developed to the foundation beam. At the ultimate state, the shear wall separated along these cracks involving the parts of the foundation beam, the pile, the transverse foundation beam and the slabs. These experimental phenomena clarified the monolithic action between the foundation beam and peripheral members.
