Seismic Performance of Square RC Bridge Columns under Combined Loading including Torsion with Low Shear
During earthquake excitations, reinforced concrete bridge columns can be subjected to a combination of axial load, shear force, flexural moments, and torsional moments. The torsional moment can be much more significant in columns of bridges that are skewed, curved, have unequal spans, or unequal column heights. Combined loading including torsion can result in complex flexural and shear failure ...
متن کاملMechanical Model to simulate the NSM FRP strips shear strength contribution to RC beams
A three dimensional mechanical model has been recently developed to simulate the Near Surface Mounted (NSM) Fibre Reinforced Polymer (FRP) strips shear strength contribution to Reinforced Concrete (RC) beams throughout the entire loading process, as function of the Critical Diagonal Crack (CDC) opening angle. It was developed by fulfilling equilibrium, kinematic compatibility and constitutive l...
متن کاملBehavior of High-Strength Concrete Rectangular Columns
This paper summarizes the test results of an extensive research program sponsored by the US Transportation Research Board of the National Research Council to examine the behavior of high-strength concrete rectangular columns subjected to concentric and eccentric loading conditions. The variables considered in this investigation were concrete strength ranging from 7.9 ksi (55 MPa) to 16.5 ksi (1...
متن کاملDynamic and Static Behavior of Hollow-Core FRP-Concrete-Steel and Reinforced Concrete Bridge Columns under Vehicle Collision
This paper presents the difference in behavior between hollow-core fiber reinforced polymer-concrete-steel (HC-FCS) columns and conventional reinforced concrete (RC) columns under vehicle collision in terms of dynamic and static forces. The HC-FCS column consisted of an outer FRP tube, an inner steel tube, and a concrete shell sandwiched between the two tubes. The steel tube was hollow inside a...
متن کاملAnalysis of Carbon Fiber Sheet Retrofitted Rc Bridge Columns
Experimental studies were conducted by some researchers to investigate the cyclic performance of CFSretrofitted columns; however there is a need to develop analytical methods which can simulate its hysteretic response. This study presents an analysis of the hysteretic behavior of CFS-retrofitted reinforced concrete circular columns. Fiber element analysis was conducted based on cyclic constitut...
