ROLE OF DISSIPATIVE CONNECTIONS ON THE SEISMIC RESPONSE OF ONE-STOREY INDUSTRIAL BUILDINGS

摘要：

This paper presents alternative design solutions for one storey-precast industrial buildings, which allow to locate the dissipation capacity of the structure in the mechanical connections preserving the integrity of the structural elements. Two design approaches adopting dissipative connections are herein proposed and numerically investigated: one with partial isolation of the floor/roof system, i.e. dissipation in the connections and still moderate damage/dissipation in the columns and another solution with total isolation of the roof-system respect to the substructure, where relative displacements between the roof-system and the substructure, i.e. columns, are opportunely controlled in the design process. Preliminary numerical results confirm the enhanced performance of the one-storey industrial buildings with dissipative connections respect to the traditional solutions, where the dissipation capacity is relied only on the formation of plastic hinges at the bottom of the columns. The isolated floor solution seems to be most effective since the structural damage and, hence post-earthquake costs of repair, is limited to the substitution of the mechanical devices of the connections.
