Abstract

Understanding the effect of depth on the strength of deep beams can be essential to ensure their satisfactory performance in the field. In Houston, Texas, significant diagonal cracking ∥maximum crack width ≈ 0.035-inches∥ was observed in several large, reinforced concrete bent caps in service. An expensive retrofit was implemented to strengthen all of the bent caps in the intersection. One reason for the poor performance of the bent caps was the incorrect association of deep beam strength to the depth of the member. In this paper, experimental results are presented that support that deep beam strength is more appropriately determined through a single-panel, strut-and-tie analysis.
