Abstract:
Observations of building performance in recent earthquakes have indicated that structures stiffened by properly proportioned and designed reinforced concrete structural walls (shearwalls) behaved better than relatively more flexible moment-resisting open frames. This paper presents some results of a combined analytical and experimental program to develop design information for earthquake- resistant reinforced concrete structural walls and wall sys-tems. The principal objective of the investigation is the development of a procedure for determining design force levels for earthquake-resistant structural walls. The results of over 300 analyses form the basis of the procedure, which involves a correlation with relevant results of the concurrent experimental investigation.
