Energy Absorbing

High strength steel composite K-type eccentrically braced frame is a new structural system, in which the link is made from low yield point steel and the others are made from high strength steel. In order to study the seismic behavior of such a structure, four one-bay one-story 1/2 scaled plane specimens were tested under the monotonic and cyclic load respectively. The failure modes and the main indexes of seismic behavior of specimens with various links length were analyzed. The results show that this new structural form is good at energy dissipation and ductility, and the way of energy absorbing by shear yield is better than by flexure yield. Under cyclic load, the main failure were concentrated at links, while the other parts of the eccentrically braced frame kept in elastic status. This kind of structure is an excellent dual resistance system and easy to rehabilitate after earthquake.
