Numerical simulation of reverse cyclic loading in precast column and pocket foundation connection
Year: 2026
Type: article
Abstract: Precast concrete connections are often critical points of vulnerability during seismic events if not adequately designed. This study investigates the cyclic behaviour of precast column-to-foundation pocket connections using two distinct reinforcement detailing strategies. In the first configuration (PC I), the connection was based on the model proposed by Canha et al. (2012), enhanced with additional corner dowel bars. The second configuration (PC II) adopted independent reinforcement for each transverse pocket wall. A G + 3 reinforced concrete structure was modelled according to Singapore codes, with detailing compliant with IS 456 and IS 13,920. Numerical simulations were conducted on 1:2 scaled specimens using ABAQUS 6.14, and results were compared with experimental data. Key parameters analyzed include ultimate load capacity, strain behaviour in concrete and steel, energy dissipation, and displacement ductility. The simulation accurately reproduced experimental trends (Hemamathi & Jaya, 2021), with average deviation within 15%. The findings provide valuable insights into the seismic performance of precast pocket connections and inform more resilient detailing practices.
