Abstract:
The experimental results from reversed cyclic loading tests on six exterior reinforced concrete beam-column subassemblies are presented. The primary variables were the ratio of the column-to-beam flexural capacity, the joint shear stress, and the transverse reinforcement in the joint. The specimens were subjected to cyclic load reversals at deflection levels intended to represent the levels that could be obtained during a moderate or severe earthquake. The results are compared with the existing design recommendations. It is concluded that in some cases the present design recommendations could be safely re-laxed.
