The Seismic Category I Structures Program: Results for FY 1986
The accomplishments of the Seismic Category I Structures Program for FY 1986 are reported. The background leading to the FY 1986 Program Plan is summarized and the design of a new geometric configuration of a reinforced concrete shear wall test structure is described. The report discusses static and seismic testing of two of these structures, a 1/4-scale, 1-in.-thick shear wall model of microconcrete and a 4-in.-thick shear wall prototype. Results and conclusions regarding degrading stiffness characteristics, natural frequencies, and scalability of microconcrete with actual concrete are compared with past fiscal year results. Possible base rotation effects for the large structure are examined analytically. Finally, tentative conclusions are stated regarding the degrading stiffness and scaling of these structures and recommendations are made about future seismic testing of large structures. 11 refs., 28 figs., 9 tabs.
