What is Tunnel Reinforcement Assessment Report about?

This document summarizes the design of longitudinal reinforcement for the top slab of a tunnel located at KJB. The key forces acting on the slab are a factored moment of 108,045,000 Nm and no factored shear or axial force. The slab has a width of 1000 mm, depth of 500 mm and concrete cover of 70 mm. With a concrete strength of 14.6 MPa, the required steel ratio is calculated to be 0.00251 and the required steel area is 1079.7 mm^2. Based on the calculations, 4 bars of 19 mm diameter spaced at 250 mm are pro
