Structural design is an organized investigation to determine the most cost-effective specification of a structure or structural element to safely carry the anticipated load. By using structural design, we can create structural members that are the right size, grade, and strength to withstand the internal forces determined by the structural analysis. Structural design is a part of Structural engineering which is a sub-division of civil engineering. Structural engineers are trained to design the structural elements accurately and supervise during construction to ensure the proper implementation of the structural design. 

Objectives of Structural Design
1. Create a structure that can endure all applied loads without failing throughout its service life.
2. Obtain the structural members’ economical dimensions
3. Examine the rigidity, stability, and strength of structures.
4. Maintain structural integrity
