STAIRCASE

Staircase is a confusing to most fresh engineers. The staircase drawings is done after the design. Always, the point load from the column/stiffener supporting the mid landing is not design for in the beam or column. It is even more complicated when due to higher floor height, more than one landing is required. Fresh engineer is advised to pay special attention to visualise the staircase system, especially when go to the site.

Staircase ultimate loading = 1/2 x length of staircase x 18 kN/m2, to be checked upon completion of design.

Landing beam

The landing beam midway between floors is never shown on the layout. The height of the column supporting the landing beam is about 1.5m, therefore at every 3m floor height there is one landing beam.

Beam B1 and B4 carries half of the staircase weight which is 18 kN/m2 and slab loading. The landing will carry half of the staircase weight in addition to brickwall height.
