Abstract:
An analytical study of load-deflection responses of double-curvature reinforced
concrete squat walls is summarized in this paper. Prediction of load-deflection responses consists
of cracking, ultimate, and post strength points. The cracking point in the load-deflection curve is
calculated using a procedure of strength-of-materials. The ultimate strength is defined as the
smaller of flexural and shear strengths where the flexural strength is estimated using a sectional
analysis, and the shear strength is predicted based on softened strut-and-tie model. The
corresponding lateral deflection is estimated by summation of flexural, shear, and slip deflections.
Prediction of the post strength point is estimated using the modification of ATC-40 suggestion.
The comparison of calculated and previously reported experimental results indicates that the
calculated results of the proposed procedure correlate reasonably well with the experimental
results.
