Structural Analysis and Design of a Warehouse Building

In structural analysis, FEM is used to investigate how the applied forces will affect the product design. Complex structures are analysed better with the help of FEM method because hand calculations are not able find the solu-tion. Highly powerful computers are essential since FEM method involves solving numerous simultaneous equations.
