Abstract | Exterior beam-column joint is typically the weakest link in a limited-ductile concrete frame structure. The use of diagonal haunch element has been considered as a desirable seismic retrofit option for reducing the seismic demand at the joint. Previous research globally has focused on implementing double haunches, whilst the performance of using single haunch element as a less-invasive and more architecturally favourable retrofit option has not been investigated. In this study, the feasibility of using a single haunch system for retrofitting RC exterior beam-column joint is explored. This paper presents the key formulations and illustrates its effectiveness by investigating the changes in the shear demand at the joint through a case study. |
