| Building code provisions for the seismic design of reinforced concrete walls are drafted primarily for tall slender walls although most reinforced concrete walls in building and nuclear structures around the world are squat, having a height-to-length ratio of 2 or less. Results of prior tests of small-to-large scale squat walls are investigated with the objective of updating and expanding design procedures for squat walls. Test data from the early 1950s through the current day are studied to understand the influence of aspect ratio, rebar ratio, axial load and loading history on the ultimate shear strength of rectangular squat walls. |
