The table is valid for slenderness ratio up to 6 and loading with zero eccentricity. The permissible stress for random rubble masonry may be taken as 75 percent of the corresponding stress for coaraed walling of similar materials.
This factor is applicable for or below a lateral support may be taken to be 6. The strength of ashlar masonry natural stone masonry of massive type with thin joints is closely related to intrinsic strength of the stone and allowable working stress in excess of those given in the table may be allowed for such masonry at the discretion of the designer.
The values given fat basic compressive stress are applicable only when the masonry is properly cured. This factor. Linear interpolation is permissible for units having crushing strengths between those given in the table.

The minimum thickness of the foundation of the edge should not be less than mm. In case the depth to transfer the load to the ground bearing is less than the per- missible angle of spread, the foundations should be reinforced. The least dimension should be 60 cm circular, square or rectangular.
