Seismic Performance of Reinforced Concrete Beams with Low Strength Concrete

Abstract eng:
Two series of experimental works concerning low strength concrete of the existing reinforced concrete buildings was performed, in order to provide the appropriate seismic evaluation method for low strength concrete buildings in this study. Material tests of low strength concrete were performed to obtain the fundamental characteristics of low strength concrete. Then, the monotonic loading tests of beams whose parameters were concrete strength and stirrup ratio were performed to investigate the shear capacity of the structural member used low strength concrete. From test results it was founded that modified Popovics model for stress strain curves of concrete was applicable for low strength concrete, and shear capacity could be estimated by the present formula based on arch and truss theory.
