### Introduction to Ship Structural Members
Ship structural members are the fundamental components that form the vessel's hull and superstructure. Their primary purpose is to provide the necessary strength and stiffness to withstand the various forces and stresses encountered during its operational life. These forces can be categorized as follows:
1. **Global (Primary) Stresses:** Longitudinal bending stresses (Hogging and Sagging) experienced by the entire hull girder due to uneven distribution of weight and buoyancy.
2. **Local (Secondary) Stresses:** Stresses acting on a specific area of the ship's structure, such as hydrostatic pressure on the shell plating or cargo weight on the tank top.
