Steel Design (Moment and Shear Check) (For Simply Supported)

This document contains summaries of steel design checks for bridge and port projects. It analyzes sections under bending moment and shear force and checks if requirements are met. For a bridge beam, the moment and shear checks as well as deflection are within acceptable limits. For a port structure, the moment fails the check while shear exceeds capacity. A column is also analyzed under an axial load and found to be adequate.
