Tutorial 6: Hand Calculations Illustrating Load Rating According to LRFR

This section details the rating calculations for span 1, beam 2 from Tutorial 6. The purpose of this section is to highlight the computation of rating for prestressed concrete girders, assuming we have the design and analysis results from the program.

The general load-rating equation in LRFR is:

R F = ϕ c ϕ s φ R n γ D C D C γ D W D W γ L ( L L + I )
