Filter by Keyword4 report(s) found with reinforcing bars in the keywords field 1 - 4 of 4 With the development of accelerated bridge construction (ABC), the seismic performance of typical ABC column-footing connections has been evaluated in high earthquake-prone states, like Utah, California, Nevada, and Idaho. But to date, the current literature has yet to fully examine the impact behavior... A numerical model simulating the seismic behavior of precast concrete columns confined with glass fiber reinforced polymer (GFRP) spirals and longitudinally reinforced with steel or a combination of steel and GFRP bars was developed using the Open System for Earthquake Engineering Simulation (OpenSees).... Compared with conventional lap splicing, mechanical splicing is an alternative method of connecting bars in reinforced concrete (RC) structures, and is used mainly to reduce bar congestion in joints. Recently, mechanical bar splices, which are also referred to as bar couplers, have been used in laboratories... The use of Carbon Fiber Reinforced Polymers (CFRP) for the repair of civil infrastructure has been on the rise. Most studies have focused on the effect of CFRP to increase the stiffness and strength of reinforced concrete beams or columns. Limited attention has been given to the effect of CFRP on mitigating... |
