Steel flush endplate beam-column connections behavior is commonly described by the moment-rotation, M-φ, relationship, which characterized two essential terms; resistant moment, Mj, Rd, and initial rotational stiffness, Sj, init. A great amount of concerted effort has been invested worldwide to either experimentally or analytically describe these properties due geometrical material variations. ...

Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...

In reinforced concrete structures, the beam-column connection area has a considerable influence on behavior of structure. The use fiber-reinforced polymer FRP to strengthen connections in Reinforced structure can be one solutions transform this area, thus improving structure, which is achieved through carbon achieve high-strength Investigations have been conducted using finite element modeling....

This paper presents nonlinear elastic dynamic analysis of 3-D semi-rigid steel frames including geometric and connection nonlinearities. The geometric nonlinearity is considered by using stability functions and updating geometric stiffness matrix. The nonlinear behavior of the steel beam-to-column connection is considered by using a zero-length independent connection element comprising of six t...
