Abstract

For buildings to resist and properly dissipate energy during earthquake, suitable connections are those which allow plastic hings develop in beam neither connection elements or welds should fail or break, nor PANEL ZONE should be damaged during earthquake. BUTTRESS CONNECTION is one that meets all such requirements. A full scale model of this connection is tested in the University of Berkeley. During the research the connection is modeled by finite element method with special consideration of POST BUCKLING EFFECTs and calibrated with experimental data. Two buttress plates in the top and bottom of beam as well as web stiffeners of beam and column are arranged in the form of a truss and created a rigid zone so PLASTIC HINGE is developed in the beam, the elements of connection do not fail, stress concentration in weldes is low and weldes do not damage during loading and plastic zone remained elastic. The effect of buttress plates in top and bottom and web stiffener of beam is studied. For studying, any of these plates are removed and under a new connection is loaded. The results show that if buttress plates are removed, even though plastic hing is developed in the beam but stress concentration is increased in the weld, connection zone is damaged and plasticity is developed in PANEL ZONE. If web stiffener of beam is removed, PLASTIC HINGE is developed in connection zone and the connection fails.
