Comparative analysis of collapse loads of slabs supported on orthogonal Sided frames with beam/column joint fixed

This research evaluates the collapse loads of slab supported on orthogonal sided frames with beam/ column 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. Loading of the RC frame model was done by a fabricated loading box of 1.0 ×1.0×3.0m size place on top of its slab. Sands were poured into the panel using head pans. The weight of sand on each head pans (1.84KN). Two dial gauges were used; one was set at the center of the bottom of the slab while the other was set below the center of the bottom of the beam to monitor and measure the deflection at ten head pans of sand
