Shear Transfer in Thick Walled Reinforced Concrete Structures Under Seismic Loading
The mechanism of membrane shear transfer under cyclic loading in thick-walled cracked reinforced concrete structures is studied. The specimens incorporate interface shear transfer and dowel action acting both alone and in concert. The results are used in a dynamic analysis program to predict nonlinear response of containment vessels. The work reported here includes: (1) experiments on specimens with 1/2 to 3/4 inch diameter reinforcing bars crossing a crack; (2) development of a mathematical model to predict stiffness characteristics of dowel action in thick concrete sections; (3) dowel action experiments (under cyclic loading) to correlate with the mathematical model predictions; (4) a dynamic analysis program that accounts for the non-linear load-slip behavior at a crack carrying reversing shear stresses; and (5) results of experiments on specimens with large bars (no. 14 maximum size) where shear is carried by combined dowel action and interface shear transfer.
