About Design of Masonry StructuresMasonry structures upto three storeys or maximum four storeys are not very uncommon in India. Most of housing boards, Development Authorities construct housing flats upto three/four storeys and masonry is definitely economical. National Building Code of India (SP-7) provides all the required design tables, nomograms and description on masonry design.
Recommendations of IS 4326 for seismic detailing in masonry structures shall be seen. RCC bands at Plinth level and Lintel Levels is a must in masonry structures.The vertical bars at corners of rooms along with vertical bars around openings shall be provided as per details given in IS 4326.
Brickwork is generally available in three classes:
- 1st class Bricks have crushing strength not less than 105 Kg/cm2
- 2nd class Bricks have crushing strength not less than 75 Kg/cm2
- 3rd class Bricks have crushing strength not less than 35 Kg/cm2
For buildings over two storeys, 1st class brickwork is needed For buildings upto two storeys, 2nd class brickwork can be used. 3rd class bricks can be used in exceptional circumstances of non availability of good bricks , only for single storeyed.
Masonry structures must have system of walls with cross walls at regular interval( about 3.0m to 3.5m c/c). In case cross walls are not available, need for provision of RCC columns to laterally support the long wall arises. Opening in masonry structures must be properly planned in consultation with Architect. Zones of stress /load concentrations must be identified. Introduction of RCC columns may be resorted where stress is exceeding.
All beams must rest on PCC bed blocks/or extended bearing length on masonry to keep the stress on brickwork within limit.
Mortars for brick work:
This shall be provided as per design requirements. Mahabharat episode 244. Very approximately:
CM 1:6 – single storeyed (can be 3rd class brick in exceptional cases if design permit)
CM 1:5 – Ground storey of Two storied( with min 2nd class brick)
CM 1:4 – Ground storey of Three storied( with First class brick)
CM 1:3 – Ground storey of Four storied( with First class brick)
Curing of brick work – This is very neglected area and 10 to 14 days curing must be emphasized.
Provision of plasters also help in strengthening the walls Free standing Boundary walls must be in CM 1:5 minimum.
SP20 of Indian Standard (IS) Code provides all the guidelines for design and construction of brick masonry.

Download the Excel based calculation Sheets for creating the perfect design of any retaining walls as well as verifying the suitability of this retaining wall against overturning and sliding forces.
A retaining wall refers to a structure that is designed and built up to defend the lateral pressure of soil, when any alteration occurs in ground elevation that surpasses the angle of repose of the soil. Retaining walls are useful for developing basement under ground level, wing walls of bridge and to sustain slopes in hilly terrain roads.
Masonry Design Program
Retaining wall is formed with masonry and reinforced concrete. For masonry retaining wall, the depth of wall is raised along with height as masonry withstands the lateral pressure by its weight.
So, it is also known as gravity retaining wall. Whereas the reinforced concrete retaining wall withstands the lateral pressure by structural action like bending and leads to thinner section.
The main objective of a retaining wall is to hold or preserve soil behind it. Different types of materials are utilized to produce retaining walls like concrete blocks, poured concrete, treated timbers, rocks or boulders. Some can applied easily, others contain a shorter life span, but all can maintain soil.
In order to design and install the retaining walls, the emphasis should be given on identifying and neutralizing the trend of the retained material to drive downslope because of gravity. This produces lateral earth pressure behind the wall that is subject to the angle of internal friction (phi) and the cohesive strength (c) of the retained material, along with the direction and magnitude of movement the retaining structure undergoes.
