LOAD BEARING MASONRY BUILDINGS
Since stepped footings of masonry are continuous strip foundation
,it has better resistance to unequal settlements as compared to isolated column foundations.
However , it is always wise to introduce rcc columns , even of small dimensions to take care of point loads at following locations:
Front Balcony - The cantilever beams carrying Balcony load exert additional reaction at cantilever ends in form of M/L effect. Also the cantilever beam must continue at back to at least twice the cantilever span to have adequate FOS against overturning. Rcc column at cantilever face of beam shall be introduced to protect masonry excessive masonry stresses at root of cantilever.
Corridors , if more than single storey , needs to be supported on rcc columns . For single storey corridors brick piers can easily support.
Large openings , or a no of openings like windows and doors in succession in a wall with small brick pillars available between doors and window. The front walls having such openings with much less brickwork area , needs to be supported on rcc columns with rcc beam over wall .
Hall having longer walls without any cross walls. It is better to introduce rcc columns at about 3 to 3.5m. Though wall in which these columns are sandwiched are gravity load bearing, for EQ in its orthogonal dir , rcc column to be designed to take entire EQ. |
