• 20 specimens were tested with the observation of five kinds failure modes. Angle thickness, horizontal and vertical bolt pitch affected mode connection. Significant plastic deformation appeared in both legs. The prediction formulas for performance connection are proposed. A mechanical model bolted angle is established verified. In this paper, an experimental study was carried out on under uni...

An analytical approach based on modified Bouc-Wen-Baber-Noori model has been proposed in this paper for predicting the hysteresis behavior of reinforced concrete beamcolumn joints with limited transverse reinforcement. The analytical model presented in this research is able to capture the characteristics of non-seismic detailed beam-column joints such as stiffness and strength degradation and p...

The rapid development of China’s construction industrialization process has led to increased research into prefabricated building structures. In comparison cast-in-place construction, buildings offer many advantages. Increasingly important been on joints’ seismic performance. A beam, slab, column, and wall’s connection affects its performance, each joint different characteristics. light this, t...

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....

Moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.After the earthquake in Northridge 1994,Kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.In order to remedy to avoid similar situations in future earthquakes,researchers introduc...

Upgraded design standards coupled with the damage caused by natural disasters have led to development of smart materials potential modernize current construction practices. This investigation proposes a nonlinear finite element (FE) model for evaluating performance beam–column joints (RC-BCJ) reinforced shape memory alloys (SMA) and steel rebars. The was validated based on accredited experiment...

In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...
