AbstractWith spreading of population and increasing of instruction, and also because of limited resources and materials, the demand for using novel materials in building industry has increased. The reinforced concrete columns and steel beams are used in structures with composite moment frame (RCS). Use of compression strength in proportion with concrete and bending strength of steel beam has bestowed these structures less weight than that of concrete structures and made it easier to access the measure of strong column - weak beam especially within long span in these structures. The most important part of these structures is connection of steel beam with the reinforced concrete column. These connections are divided into two general groups of connection with bracing beam and with bracing column from the joint. This paper aims to study the seismic behavior and parameters of RCS composite frame composed of steel beams and strong concrete column. The finite element method was analyzed by ABAQUS software and data analyzed by Excel.

Composite Joint

In order to improve the constructability and meanwhile ensure excellent seismic behavior, an innovative bolted endplate connection to steel beam and reinforced concrete column (RCS) was developed, and three full scale model joints with or without floor slab were tested under simulated seismic loading. The proposed composite joint is characterized by an extended endplate which is welded to steel beam with reduced sections in factory and then bolted to reinforced concrete column using high-strength steel rods in field. The effect of material strength and concrete floor slab on the seismic behavior of joints was studied. Experimental results indicated that both specimens without floor slab exhibited good ductility and energy-dissipating ability with full plastic hinging formed at the reduced sections of steel beam. However, owing to the effect of floor slab, the beam sections became unsymmetrical and positive moment strength of the joint was increased significantly. The specimen with floor slab fractured at the weld between the bottom flange of the beam and the endplate, and the failure mode resembled what occurred during the Northridge earthquake.

To improve the bearing failure behavior of the exterior steel beam-reinforced concrete column joints composed of reinforced concrete columns, joint details using steel column was proposed. Steel column was attached to the lower flanges at right angles to the steel flange. The objective of this study is to clarify the effectiveness of proposed joint details experimentally and theoretically. To clarify the influence of steel column on the bearing failure of the joint, seven T-shaped subassemblages were tested under reversed cyclic loading. All specimens had the same cross sections of the steel beam. The experimental variables were the embedded length of the steel column, whether there is the end plate at the tip of the embedded steel column, and, the arrangement of transverse reinforcement ratio surrounding the steel column. The following remarks can be drawn from the test results. 1) In case of the specimen with a short embedded length of the steel column, the punching shear failure on the upper surface of the steel beam flange was remarkable when the maximum strength was reached. However, in the specimen with long embedded length of steel column, it was not observed the punching shear failure. 2) The maximum strength increased with the embedded length of the steel column. Further, the maximum strength of the specimen with the embedded length of three times of the steel column depths is subjected to bending yield strength of the steel column. 3) It was shown that the transverse reinforcement to surround the steel column and the end plate were necessary to improve the bearing failure of the joint.
