This research aims to analyze the behavior of precast structures in Malaysia when subjected to seismic activity, specifically focusing on the connection between beams and columns. To achieve this, a new method called the Beam-Line Method (BLM) has been developed and utilized to model and analyze the seismic performance of these connections in precast frames. The study employs non-linear static pushover analysis and non-linear dynamic time history analysis to comprehensively evaluate the structural response under seismic loads. Additionally, the seismic performance of the building is assessed by combining the seismic capacity curve obtained through pushover analysis with the elastic response spectrum curve of the earthquake. Furthermore, the study investigates the significance of connections in the overall structural performance by calculating moment rotations in the beam-to-column connection. These are then utilized in the seismic analysis of the entire frame. The outcomes of this research provide valuable insights into the seismic behavior of precast reinforced concrete beam-to-column connections, thus informing future design and construction practices to enhance the seismic resilience of such structures.
