beam to column welded connection with radius cut on beam flange is known as rigid connection that provides acceptable ductility for special moment resisting frame (smrf). in order to decrease the cost of construction and to provide an easy-to-construct structure, the new method is available for reducing the beam section based on drilling on beam flange , known as drilled flange connection (dfc)...

the basic strategy of reduce the ductility demand and related concentrated tensions at moment resistance connections is reduce the section of the beam at connected region to column. by this method plastic hinge done at the reduced cross section and this local reduction decreases the demand of the components of connection. on this basis, in present study a new beam-to-column moment connection wi...

In order to realize the design concept of “strengthened column and weakened beam, strengthened connection joints components” ensure improvement joints’ bearing capacity transfer plastic hinges along beams far away from ends, this paper proposes a new type prefabricated with strengthen-weaken beam-column connection, changes multiple parameters. Six joint models are designed for finite element an...
