Earthquake Simulation Tests and Associated Studies of a 0.3-Scale Model of a Six-Story Eccentrically Braced Steel Structure

摘要

The report summarizes the research conducted in the Six-Story Eccentrically Chevron Braced Steel Building Structures Phase of the U.S.-Japan Cooperative Earthquake Research Program. The selection, design and testing of the prototype are discussed and a review of the design of the eccentrically chevron braced prototype, in accordance with the 1985 UBC, 1984 ATC 3-06 and 1986 SEAOC, is presented. The results of the static and dynamic analyses of the prototype are discussed. The design, construction and instrumentation of the model are described and its mechanical characteristics are compared with those results predicted by DRAIN-2DX. The experimental program, the earthquake simulator tests and the data acquisition and processing techniques, in addition to the predicted strength and response of the model, are discussed in detail.
