This research work evaluates the collapse loads of slab supported on orthogonal side ended frames with column/beam joint fixed. Two frame models were investigated (one with Moment of Resistance of slab (MRS) > Moment of Resistance of beam (MRB) and the other with Moment of Resistance of slab (MRS) < Moment of Resistance of beam (MRB)). A reinforced concrete prototype of 3m*3m*3m frame with a reduction factor of 3 was designed and constructed. A model of it constructed and cast with a micro concrete of 1:6 mix ratio. The models were allowed to cure for 28days before being loaded directly until collapse. The estimated collapse load for slab and beam were 20.36KN/m and 52.27KN/m respectively. The actual collapse loads of the frame models (MRS > MRB and MRS < MRB) were 69.04KN/m and 49.68KN/m respectively. The frame model failed by flexural failure at the beams /column joints. The actual collapse load of 69.92KN and 49.68KN respectively were greater than that of the estimated collapse loads of beam and slab comparably. Also the MRS > MRB frame model is stronger than that of the MRS < MRB frame model.
