Tying of edge columns, the horizontal ties anchoring the columns nearest to the edges of a floor or roof should be capable of resisting a factored tensile load, acting perpendicular to the edge, equal to the greater of the tie force as calculated in (a) above, 75 kN or 1% of the maximum factored dead and imposed load in the column immediately above or below that level. (Code of practice for the structural use of steel 2011 – 2.3.4.3 Avoidance of disproportionate collapse).

The design wind force on a building or parts of a building shall be calculated in accordance with sections 4, 5 and 6 unless the building has significant resonant dynamic response. (Code of Practice on Wind Effects in Hong Kong 2004 – 3 – Definitions).

Flat slab, a slab supported without beams by columns. The slab may be formed with or without drops and either be solid or the slab soffit may comprise a series of ribs in two directions (waffle or coffered slab). (Code of Practice for Structural Use of Concrete 2013 – 1.4.2 Terms specific to flat slabs).

Plain wall, a concrete wall containing either no reinforcement or insufficient to satisfy the minimum quantities of reinforcement. (Code of Practice for Structural Use of Concrete 2013 – 1.4.4 Terms specific to walls).
