ABSTRACT

Some general notes on stairs are given in section 6.1.4. For details of characteristic imposed loads on stairs and landings, and horizontal loads on balustrades, refer to BS 6399: Part 1. Stairs forming monolithic structures are generally designed for the uniformly distributed imposed load only. Stairs that are formed of separate treads (usually precast), cantilevering from a wall or central spine beam, must be designed also for the alternative concentrated load. Some general information on stair types and dimensions is given in Table 2.88 , and comprehensive data is given in BS 5395.
