Abstract
An experimental program was developed to study the strength and deformation capacity of tilt-up structures with plywood roof diaphragms. Two models of tilt-up systems were constructed and tested in the laboratory. The structures were representative of one-story warehouse construction in the western U.S. The overall dimensions of the two test specimens were the same; however, the number and distribution of reinforced concrete wall panels were varied. Each specimen was subjected to a series of lateral load reversals.
Two aspects of the measured response of the test specimens are discussed in this paper: the in-plane displacements of the plywood roof diaphragm and the transverse response of the perimeter wall panels. The wall panels experienced nearly rigid-body rotation during the entire testing series, and the observed nonlinear response of the test specimens may be attributed to the inherent flexibility of the plywood diaphragm.
