Glass balustrades loadings

 Table 1 specifies minimum horizontal imposed loads appropriate to the design of parapets, barriers, balustrades and other elements of a structure intended to retain, stop or guide people to protect a change in level. The loads given in Table 4 should be treated as the un-factored for design purposes. The uniformly distributed line load and the uniformly distributed and concentrated loads applicable to the infill should be considered as three separate load cases. In design, the horizontal uniformly distributed line load should be considered to act at a height of 1100mm above FFL level, irrespective of the actual height of the element. For staircase the pitch line drawn through the nosings of the stair treads should be used.

For all types of activities given in Table 1, the parapets, barriers and balustrades should be designed for a vertical load. This vertical load should be either a concentrated load of 1 kN or a uniformly distributed load of 0.6 kN/m, whichever gives the lesser condition in combination with the recommended horizontal loading of Table 1.

This combination of loads should be taken into account in the design of relevant elements of the structure that support the parapets, barriers and balustrades .for more information in regard handrail to accommodate loadings to give a guidance to enable the correct handrail been installed
