This architectural drawing is the 2D design of the REINFORCEMENT OF THE STEPS in detail AutoCAD drawing, CAD file, dwg file. The behaviour and reinforcement of a one-way stairwell connected to slabs. Because the staircase continues to slabs at its base and top, negative bending moments are formed at the supports, necessitating the use of rebars at both ends.
