Long-Term Performance of Seismically Rehabilitated Corrosion -Damaged Columns
This project investigated the long-term seismic performance in cold regions of corroded reinforced concrete columns that are repaired using advanced composite materials (ACM). Although the success of ACM in upgrading the structural response of reinforced concrete columns has been established in the …

Short and long term performance of Canadian TSE-listed acquirers
… this study empirically tests short- and long-term security price performance of Canadian TSE-listed acquirers. The cumulative abnormal return (CAR) and the buy-and-hold abnormal return (BHAR) methods were use for the short- and the long-term studies respectively. In the short-run study, …

Early-age behavior of CRCP and its implications for long-term performance
… on design variables and their effects on CRCP performance. Most advanced CRCP designs use the mechanistic-empirical approach. In this approach, structural responses of CRCP due to environmental and traffic loadings are computed. Damage to concrete is estimated over time, and pavement distress …
