Abstract:
Exterior and corner beam-column joints without transverse reinforcement can be vulnerable to shear failure under earthquake loading. A database of past tests on such joints is presented, emphasizing joints that failed in shear prior to yielding of the framing members. Trends in the behavior are observed. Available shear strength models are evaluated. Two new shear-strength models are introduced: one based on strut-and-tie modeling and another based on an empirical study of critical parameters. The new models show good correlations with test results.
