Deformation Limit
     Deformation can be linear deformation or angular deformation. Linear Deformation is deflection. Allowable deflection is "span / 300". The Columns sway in horizontal direction. The allowable sway is "height / 300". The deflection can be in horizontal plane or vertical plane. The allowable Angular deformation is 0.5 Degree. The limits of deformations are empirical. All the limits indicated for deformation are suggestive. Suitable precautions Should be taken to limit the deformation of critical and lethal equipment Against performance related issues. The deformation of single member can be calculated using standard formulas. The deformation of assemblage of members into truss and frame shall be computed using computer software, and limited to the respective allowable.
