Performance of a Ductile Hybrid Post-Tensioned Beam-to-Column Connection for Precast Concrete Frames under Seismic Loads: A Review

The performance of precast concrete frame structures against seismic loads mainly depends on the beam-to-column connection. A ductile hybrid connection consists unbonded post-tensioning steel and bonded reinforcement bars, both which provide overall moment resistance to frame. Post-tensioning acts as a restoring force brings structure back its initial position upon unloading. Mild an energy dissipator yields in tension compression. To evaluate structures, structural engineer requires extensive knowledge complex nonlinear behavior Standardization mass produce is one benefits construction, but with standardization design there severe risk. All previous earthquakes have clearly shown that continuous repetition accepted practice without proper engineering review can lead disaster. It important understand how different parameters influence loads. present study helps engineers researchers detailed post-tensioned connections. This focused connections, studies development evaluations evaluation frames
