Explain the difference between design and analysis as it app

Explain the difference between design and analysis as it applies to reinforced members. How does input data for analysis differ from design?

Solution

Structural Analysis:: It is the process by which we find out how a structure or a member of a structure behaves under applied loads. That is means finding out internal forces (axial force, shear force, moment), stress, strain, deflection etc. We need these data for the structural design.

Structural Design:: It is the process by which we find out safe and economical specifications of a structure or a member of the structure. That is means finding out member steel section, cross sectional dimension, amount of reinforcement etc. to withstand the internal forces that we have got from structural analysis

Input data for the analysis are the loads from different components which a structure may be subjected during its life time. while the input data for the design are the various response caused in the structure due to applied loads in analysis.
