Reinforced concrete bridge wall piers constructed using older codes perform inadequately during strong earthquakes. Deficiencies include short reinforcement lap splices, insufficient steel reinforcement ratios in the longitudinal and transverse direction, and inadequate seismic detailing. The research presented in this webinar will address seismic deficiencies found in older reinforced concrete bridge wall piers and discuss retrofit methods that are efficient, effective and offer great cost-savings in repairs and increase longevity.
