| Riassunto: | This experiment was undertaken to study the impact of concrete strength on the ductility of reinforced concrete frame
structure. Two half scale interior joint with monolithic transverse beams and slab from a six storied residential building
were selected for the experiment. The joints were constructed without any shear reinforcement within the joint region
to evaluate the contribution of concrete strength in bond stress between the longitudinal reinforcement and concrete.
Bond stress has important specific roles on the ductility of the joint in particular and on the ductility of the global
structure in general. The models were subjected to incremental static cyclic lateral loading provided by hydraulic jacks
under constant axial loading. Deflections and rotations were measured by dial gauges and a video extensometer. It is
found from the study that ductility of the structural members i.e. beams, columns and joints increased remarkably with
increased concrete strength. |
