Masonry Column Design
The scope of this calculation module is to design a masonry column for given axial loads under eccentric conditions taking the masonry properties and strength into consideration. The application checks the compressive strength adequacy of the column.
- The design module allows the user to capture the actual site or design requirements via various options such as,
- Masonry properties
- Masonry constructions
- Moreover, in order to help the user to better use the module material-based choices are also given such as,
- Type of bricks used and their properties
- Clay and calcium silicate bricks
- Autoclaved aerated concrete blocks
- Aggregate concrete blocks (of various porosity)
- Solid aggregate concrete blocks laid flat
- Solid aggregate concrete blocks collar jointed
- Masonry unit category (as defined in code provision)
- Construction control category (as defined in code provision)
- The slenderness ratio along major and minor axis is calculated.
- The height and effective height of the column is equal, as the length of the column is taken as the distance between lateral supports.
- The ratio of masonry unit height to least horizontal dimension of masonry unit and the ratio of masonry unit height to effective thickness of masonry wall has been limited to a definite range for different wall types.
- The absolute value of load eccentricity should not be greater than half the value of column dimension along the respective direction.
- The masonry column calculation is carried out only for short columns.
- The capacity reduction factor is calculated from the absolute value of load eccentricities.
- The design vertical load resistance is calculated after applying a compressive strength correction factor as the respective area of a column is small.
