Static Pushover Analysis of Beam-Column Joints in Frame Structures

Abstract There are many factors influencing the yield mechanism of "strong column and weak beam", which is not required by the current seismic design of frame structures in earthquakes. In this paper, pushover analysis is done by creating ETABS framework model. Firstly, this paper analyses that cast-in-place floor will increase the stiffness and bearing capacity of frame beams. Then, this paper analyses the amplification factor of frame beam stiffness under combined loads. Finally, this paper achieves the effect of "strong column and weak beam" by controlling the reinforcement at the end of the beam.
