Details of model frame (unit: mm). a Plan of model frame and details of slab reinforcement (slab thickness 30 mm). b Column section. c A, B, C axes beam section. d 1, 2, 3 axes beam section. Note Spacing of stirrups is 15 mm in beam and column ends, the critical regions are 200 mm in transverse beam ends, 300 mm in longitudinal beam and column ends; all longitudinal reinforcements (top and bottom) in frame beams are fully anchored in the joints of frame.
