Perpendicular cantilever floor framing uses extended joists, projecting from the main structure, to support the floor. This design leverages the principle of leverages, where the overhanging part is balanced by a counterweight within the building. It requires double joist framing at sides, adding rigidity and strength. For adequate load-bearing capacity and stability, the cantilever should extend into the building twice as far as it projects outside. This ensures a safer, balanced, and more robust structure. Such framing allows overhanging spaces without additional pillars, enhancing architectural flexibility and spatial utilization.
