Abstract
This report addresses the development of seismic design criteria for industrial storage racks. The development of loading criteria, the testing and interpretation of test results of a series of experiments on full size rack assemblies, subassemblies, and rack components are described. Forced vibration tests are needed to obtain information on natural frequencies, mode shapes, and damping characteristics, while the behavior of connections and members as well as the stability of the frame-type racks are studied from cyclic loading tests. Objectives of the study include the following: (1) determination of the load-deformation response of cold formed steel members and their connections under cyclic loading similar to that expected under severe seismic excitations; (2) development of mathematical models of response characteristics as needed for subsequent analytical studies; and (3) development of standard seismic testing procedures which can be utilized by the rack manufacturing industry for seismic qualification testing. Types of tests include cantilever, portal, full-size rack (including longitudinal and transverse tests), and dynamic tests.
