To improve the lives of senior citizens, Cornell students have developed concepts for a portable machine that allows seniors to put on their pants without bending over, a winter coat that provides protection from the impact of a fall and a jacket that is easy to put on and take off while sitting in a wheelchair.
To achieve this goal, a two-span, substandard single-column bent RC bridge, typical of older construction practice, is utilized as a reference bridge to illustrate the impact of repair jacket application on damaged bridges subjected to AS attacks.
Results indicate the dramatic impact of repair jacket application on post-MS resilience of damaged bridge piers up to 45.5 % increase of structural collapse capacity—subjected to aftershocks of multiple intensities.
The impact of jacket application incorporated in more complex numerical models considering soil-structure interaction, bearings at expansion joints (pounding and unseating), and abutment backfill soil effects, with the inclusion of pile-footing-pier failure would be contributory in this area.
Hence, this study aims at quantifying the impact of repair jackets on the post-MS collapse capacity of repaired bridges with substandard reinforcement detailing under AS attacks.
Quasi-steady-state numerical calculation was employed to investigate the impact of the water-cooled jacket on the heat transfer at the melt-crystal interface.
Swing jackets blend the structure of a standard jacket with the volume and flare of a capelet.
