Abstract:Reliability of I/IO scale reinforced concrete models for predicting frame behavior under severe reversing lateral loads is assessed with seven models of four full-scale beam-column joints. The joints were subjected to nine cycles of severe reversing loads with ductility factors of 5 for the last three load cycles. The properties of appropriate model materials (concrete and reinforcing steel) are presented and the effects of concrete mix proportioning and heat treatment of the reinforcing wire are described. Comparisons between model predictions and prototype results are given for moment-rotation, displacement, reinforcing stresses, and development of cracking in the beam and column. It is shown that 1/10 scale models can accurately reproduce complex prototype behavior when the model materials have the proper post-elastic properties. The tensile strength of model concrete and the bond behavior of model reinforcing are key quantities.
