6.5 Load
6.5.1
accidental load
load, which is not specifically foreseen because its occurrence is unlikely, but for which an allowance is made in design

dead load
load of constant magnitude and position that acts permanently, including self weight
6.5.3
characteristic dead load
dead load based on specified menslons and densities
6.5.4
imposed load
load on a structure or member, other than wind load, produced by the external environment and intended occupancy arid use
EXAMPLE Snow or moveabte partitions.
L5.5
wind load
load caused by wind flow around structures which exerts lateral or vertical pressure
6.5.6
characteristic imposed or wind load
load which has a probability of not more than 5 % of being exceeded where it acts unfavourably or. where it acts favourably, tile load which has a probability of at least 95% of being exceeded

7.2.1
unreinforced masonry
assemblage of units laid in a specified pattern and joined together with mortar
7.2.2
reinforced masonry
masonry in which bars or mesh, usually of steel, are embedded in mortar or grout so that all the materials acttogether in resisting forces

wall set at right angles to another to give it support against lateral forces
7.8.2
cavity wall
two parallel single-leaf walls, usually at least 50 mm apart, and effectively tied together with wall ties, the spacebetween being ieft as a continuous cavity or filed with non-load-bearing material.
