Key Differences Between Elastic and Plastic Analysis in Staad Pro

In Staad Pro, the main differences between elastic and plastic analysis are:

• Elastic Analysis: In elastic analysis, the structure is assumed to behave linearly within the elastic limit. This means that the material properties are considered to be constant and the structure behaves elastically under loads without causing permanent deformations.
• Plastic Analysis: In plastic analysis, the structure is analyzed beyond the elastic limit, taking into account the non-linear behavior of materials. Plastic analysis considers the redistribution of internal forces and plastic deformation of the structure, allowing for a more accurate assessment of structural stability and load-carrying capacity.

Both elastic and plastic analyses have their own advantages and are used in different scenarios to ensure the structural integrity and safety of buildings and other structures.
