The report summarizes current experimental research at Cornell University on lightly reinforced concrete structures. Lightly reinforced concrete framing systems, designed primarily for gravity induced loads, with little or no attention given to lateral load effects, are characterized by the following critical details: (1) longitudinal column reinforcement not exceeding 2% with lap splices located immediately above floor levels in the zone of maximum lateral load moment; (2) widely spaced column ties; (3) little or no transverse reinforcement within the joint region; and (4) discontinuous positive moment beam reinforcement with a 6-inch embedment length into the column.
