FAILURE CHARACTERISTICS OF REINFORCED CONCRETE …

preclude the FRP rupture failure. On the other hand, if more FRP is used, the concrete crushing may occur prior or just following the yielding of reinforcing steel. At this time, a maximum amount of FRP, Af,max, should be provided to avoid premature crushing of concrete. Af,max and Af,min can be determined by

Seismic response of reinforced concrete walls with lap ...

Nov 21, 2016· Six large-scale reinforced concrete structural walls were subjected to increasing displacement reversals up to failure. The effects of lap splices, splice length (60 bar diameters and 40 bar diameters), and boundary-element confinement were studied. The aspect ratio of the test walls was 2.2. Although no lap-splice failures occurred, the lap splices caused detrimental effects on the wall ...
