Simulation studies of seismic behaviour of bolt-endplate connected composite structural systems consisting of CFDST columns and steel beams frame with reinforced concrete slabs are presented in this paper. Based on fiber-section model, analytical models were developed to predict the elastic-to-plastic behaviour of the prototype frame. Analysis results indicated that the structural behaviour under the simulated seismic loadings was consistent with the expected performance objects for different earthquake hazard levels corresponding to current seismic design codes, implying that effective seismic performance of composite CFDST frame with bolted connections can be achieved. The primary analytical simulation shows the suggested bolted endplate CFDST system has the potential to offer appropriate strength and adequate stiffness for buildings located in areas of high earthquake intensity, and provides basic information for further experimental researches to validate the seismic performances of the bolted end-plate CFDST structures.

An experimental program under cyclic load is performed on two half-scale interior moment end-plate connections to concrete filled tubular (CFT) columns. Flat and curved stiffened extended end-plates were welded to the steel beams in the shop, and bolted on the site to the square and circular CFT column tubes respectively, using steel rods passing through the column. The experimental results demonstrated that both circular and rectangular end-plate connections showed similar performance in a ductile manner and the stiffener elements were effective to form the plastic hinges away from the welding zone, also the proposed curved end-plate connection with rods passing through the column in “X” shape was effective. The test specimens showed a plastic rotations capacity of 0.054 radian.

End plates welded transversely to the web of the beam and then bolted to the supporting member should provide effective, simple connections to transmit shear. However, under loading, the end of the beam rotates and moments are developed in the connection. It is essential that the end plate connection be sufficiently flexible so that the factored moment can be attained in the beam without the development of excessive moments in the connection itself. Based on the behaviour of T-sections, where the flange of the T simulates the end plate and the stem simulates the web of the beam, both when the stem is loaded in tension and in compression, analytical procedures have been developed to predict the moment–rotation behaviour of end plate connections. Good agreement has been obtained between the predicted nonlinear moment–rotation curves and the experimental curves for eight connections covering a practical range of end plate thicknesses, gage distances between bolt holes, and connection depths. With the proposed analytical expressions the designer is able to predict the behaviour of a connection to ensure it has sufficient strength and flexibility. Key words: beams, connections, deformation, design, end plates, plates, rotation, shear strength, steel, stresses, tests.

Extended stiffened end-plate connections are widely used in seismic area due to their good performance in terms of both resistance and ductility. The most of existing studies focused on the all-steel behavior of these joints, disregarding the composite action of the concrete slab that is generally disconnected. However, the presence of the concrete slab can have beneficial effects on the structural stiffness for both gravity and lateral loads. Hence, most of the building frames are usually designed considering steel-concrete composite solution. However, the slab can strongly influence the hierarchy between beam and column and the ductility of the joint. In this paper the influence of composite deck on the response of extended stiffened end-plate joins has been investigated by means of finite element analyses (FEAs). In particular, the following details have been investigated: (i) all steel joints without slab; (ii) steel joint with disconnected slab; (iii) composite joint.
