Reinforced Self-Consolidating Concrete Structural Frames
Multi-storey reinforced concrete structural frames represent some of the most congested structural elements. Placing and consolidating concrete in such structural frames imposes substantial challenges. This offers a unique area of application for self-consolidating concrete because of its inherent ability to flow under its own weight and fill congested sections, complicated formwork and hard-to-reach areas. However, research is needed to demonstrate the ability of SCC structural frames to resist vertical and lateral loads. In the present research, full-scale 3-m high beam-column joints reinforced as per the Canadian Standard CSA A23.3-94 were made with ordinary and self-consolidating concrete. They were tested under reversed cyclic loading applied at the beam tip and at constant vertical load applied on the column. The beam-column joint specimens were instrumented with linear variable displacement transducers and strain gauges to determine load displacement traces and cumulative dissipated energy. This paper compares the performance of normal and self-consolidating concrete structural frames and discusses the potential use of SCC in such application.
