In order to meet the necessity of the code for seismic design of buildings: Principle for strong connections and feebleness member. The exernal steel tube of column and steel beam are joining with three kinds of style. Containing two strengthen styles T-style stiffening plate and appending haunch. The result reveals that the two strengthen connections ultimate load are much bigger, good ductility, better seismic behavior. The deformation of the column and the region of the connection is smaller when it was broken, Indicating the connections’s globality is better and the stiffness is bigger. It avoids brittleness for breaking styles when they are given more load.

A new type of joint between Concrete-filled Square Steel Tube columns and steel beam is proposed in this paper, and the seismic behavior of this type of joint under low-reversed cyclic loading experiment is researched. Ductility behavior, dissipation of seismic energy of this joint under horizontal, repeat load are analyzed. The experimental results showed that all specimens have good ductility and energy dissipation capacity. The story angle drift ductility ratios are μ=3.23~3.63, and the equivalent viscous damping coefficients are he=0.25~0.35,which meet the needs of the code for seismic design of building.

Static Test

To investigate the seismic behavior of joint between special-shaped concrete-filled steel tubular (CFST) column and H-section steel beam, a pseudo-static test was carried out on five specimens with scale ratio of 1:2. The investigated factors include stiffening types of steel tube (multi-cell and tensile bar) and connection types (exterior diaphragm and vertical rib). The failure modes, hysteresis curves, skeleton curves, stress distribution, and joint shear deformation of specimens were analyzed to investigate the seismic behaviors of joints. The test results showed the connections of exterior diaphragm and vertical rib have good seismic behavior and can be identified as rigid joint in the frames with bracing system according to Eurocode 3. The joint of special-shaped column with tensile bars have better seismic performance by using through vertical rib connection. Furthermore, a finite element model was established and a parametric analysis with the finite element model was conducted to investigate the influences of following parameters on the joint stiffness: width-to-thickness ratio of column steel tube, beam-to-column linear stiffness ratio, vertical rib dimensions, and axial load ratio of column. Lastly, preliminary design suggestions were proposed.

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.
