Abstract:
A grid model is developed that predicts the strength and stiffness of slab-interior column connections transferring moments increased either monotonically or reversed cyclically to failure. A study is made of the effects of bond slip on joint behavior and those results used to define boundary conditions for the grid model. General principles are also developed for evaluating changes in flexural and torsional stiffness with cyclic loading. Results predicted by the model are compared to experimental results and good agreement obtained for both monotonic and reversed cyclic loading.
