Seismic Behaviour Experimental Study of the D-Type Energy Dissipating Eccentrically Brace
Because the repairing work of beam and floor after earthquake were great, and the cost were higher, the generalize application of eccentrically braced steel frame were limited. A new braced steel frame system was suggested, which was energy dissipating eccentrically brace. The experimental data of new and conventional D-type eccentrically braced steel frame system were achieved by two specimens under cyclic loading. Results indicated that the new system could put off yielding, reduce earthquake input energy and breakage of the link, reduce repairing load after earthquake, and have preferable ductility and enough lateral stiffness. The new braced steel frame system which had gained patent of invention in Chinese was practical and costly that it could be applied in present project.
