Abstract:
The results of lateral load tests on one third scale slab-column structures with realistic boundary conditions are presented. Measured moments at both internal and edge columns are compared with predictions based on methods in codes and other analytical procedures including finite elements. For all methods of prediction the lateral stiffness of the frameworks is overestimated and in some cases to a substantial extent. The lateral stiffness was also found to be influenced by cracking due to gravity loading.
