SEISMIC RESISTANCE OF FRAMES WITH VERTICALLY DISTRIBUTED LONGITUDINAL REINFORCEMENT IN BEAMS

The use of vertically distributed longitudinal reinforcement in the the beams of moment-resisting frames designed for earthquake resistance is considered. It is demonstrated that, in terms of flexural strength, beam sections with vertically distributed longitudinal reinforcement are as efficient as conventional beams with longitudinal reinforcement concentrated near the top and bottom of the section. The effect of vertically distributed beam reinforcement on the shear forces induced in beam-column joint cores is also considered. Experimental results from two near full-scale beam-column joint assemblages with vertically distributed longitudinal beam reinforcement, tested under simulated seismic loading are presented. These joint assemblages contained very little joint core reinforcement. Although the results indicated that verticaly distributed longitudinal beam reinforcement could not be used as a complete replacement for horizontal joint core reinforcement, it is clear that partial replacement by such reinforcement is possible.
