| Abstract | Two primary stair units, each comprising two treads and one riser, were tested in bending. Deflections, rotations and strains were measured and compared with theoretical values. The first unit failed at a strength of 52% of that predicted by theoretical computation. Based on the defects of this unit, the arrangement of steel in the second unit was improved. With this additional reinforcement, the ultimate strength was close to the predicted value. Based on this information, a half-scale model of a simply supported slabless tread-riser staircase was designed and tested under uniform loading. Within the elastic limit, the staircase behaved well. At a load of 1.5 times the desgin load, deformations became large. The first crack appeared at a load factor of 2 and failure occurred at a factor of 2.3. |
