Abstract

This research is aimed to study the influence of multiform column angles on bridge columns and cap beam joints. Based on analytical results, changing angles from 0 to 10 didn’t show considerable impact on displacement and acceleration of bridge models. Furthermore, The joints of cap beam didn’t play a key role by different stress and strain. Beside this, vital assesses have seen around cap beam to column joints. The analytical data indicates that significant place is lower corner of joints through strengthening. It can guide to obviate reinforcing bars consumption at the cap beam or columns, which are using many materials and spending extra money. The software used in this study was Abacus. The model was a two column bridge bent that has one pedestal. The bridge was first designed in CSI Bridge software based on the AASHTO 2007 bylaw, then re-modeled in Abacus software, and finally the effect of 7 earthquake accelerograms in 3 modes of the pedestal angle in the cap-column beam node were analyzed.
