An Experiment on Seismic Shear Capacity for HRB500 Grade R/C Frame Columns within Yield Hinge Regions
An experiment on shear capacity for HRB500 grade R/C frame columns within yield hinge regions is studied. The different failure modes for specimens within yield hinge regions are classified, and the hysteretic curves are studied. The shear contributions of stirrups and concrete for columns are analyzed in detail. Based on the experimental study, formulas for the shear capacity of reinforced concrete columns are supposed under seismic loading, and the different formulas are adopted to estimate the shear capacity for columns at different seismic levels, Both security and economy of structural design are all considered.
