Full-scale tests were undertaken to determine the bearing capacity of thin wall-ribbed reinforced concrete panels. Five full-scale panels, with variable reinforcement, were tested as bearing walls under axial and eccentric loading. Deflections, crack appearance and propagation under increasing load; behavior at junctions of thin walls with ribs; and ultimate capacity were recorded and analyzed. Results obtained were compared with calculated values based on present ACI design practice to determine if the empirical ACI design method, developed for solid walls, is also applicable for thin wall-ribbed panels. Simplified formulas are presented for thin wall panels.
