Although its successful use to upgrade the lateral load capacity of existing Reinforced Concrete frames has been the subject of a number of studies, guidelines for its use in newly constructed RC frames need to be further developed. An important consideration in the design of steel-braced RC frames is the level of interaction between the strength capacities of the RC frame and the bracing system. In this paper, results of experimental and numerical investigations aimed at evaluating the level of interaction between the bracing system and the RC frame are discussed. For these investigations, cyclic loading tests were conducted on scaled moment resisting frames with and without bracing. The experimental results are used to calibrate full-scale numerical models. A parametric numerical investigation on the effects of the main problem variables is then conducted and the influence of each parameter on the level of interaction is determined. Based on these findings, guidelines for the seismic design of the internally-braced RC frames with direct connections are provided.
