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.

Seismic Design Code

High strength steel reinforced concrete (HSRC) column refers to steel reinforced concrete column using high strength steel with its yield strength over 420MPa. So far, research on seismic behavior of HSRC columns is limited. This paper presents experimental and numerical studies on seismic behavior of HSRC columns. Two Q460 high strength steel reinforced concrete columns have been tested under low cyclic loading with constant axial compression ratio of 0.3. Flexural failure is observed in the test. From the hysteresis curves, the specimens exhibit good ductility and satisfactory energy dissipation capacity. Displacement ductility factors are larger than 2. When load descends to 85% of the peak load, the ultimate drift ratios of two specimens are 1/29 and 1/26 respectively, which meet the requirements of Chinese Seismic Design code (GB 50011). To study the seismic behavior of HSRC columns more comprehensively, a numerical model has been established for simulating the experiment using OpenSees, which adopts nonlinear beam-column element and fiber model. The numerical result fits the test data well, which validates the effectiveness of numerical model. Parametric study is then carried out to further investigate the seismic behavior of HSRC columns.
