P–Delta effects can cause a significant reduction in both the shear capacity and initial stiffness of columns and needs to be properly addressed in the design.

Abstract:

P–Delta effects can cause a significant reduction in both the shear capacity and initial stiffness of columns and needs to be properly addressed in the design. The random nature of ground motion, such as variability in intensity, frequency content, and duration, contributes to the structural response's uncertainty. Caltrans SDC introduces a method for finding a safe threshold for neglecting the P-Delta effects. This research intends to investigate the reliability of reaching the target damage level introduced by the Caltrans SDC under seismic loading through studying the response of a group of RC bridge columns. A group of 26 columns that comply with the Caltrans SDC criterion to neglect the P-Delta effects have been subjected to the Far-Field earthquake record set collected from the PEER-NGA database. The design target ductility recommended by the Caltrans SDC is compared with the maximum obtained ductility.
