Tutorials for AASHTO LRFD Bridge Design Specifications updates (10th Edition)
3D FEM Analysis Tutorial | Axial Rigidity Coefficient Example
Topics covered include modifying the 3DFEM2-Single-Span-Steel-3D-Example bridge for steel diaphragm connection data entry with axial rigidity coefficient and steel diaphragm spec check comparison.
Steel Tutorial | STL16 – LRFD 10th Edition Spec Update – Lateral Torsional Buckling Example
This tutorial demonstrates the implementation of the LRFD 10th Edition Lateral Torsional Buckling (LTB) resistance calculation. The LRFD 10th Edition spec updates introduce substantial changes to the calculation of the LTB resistance for steel structures. The tutorial will walk through these changes, go over the several control options for LRFD and LRFR analysis methods related to the LTB resistance calculation, and introduce the new spec article output.
Tutorials for AASHTO Manual for Bridge Evaluation updates (3rd Edition, 2024 Interim Revisions)
Feature Tutorial | MBE 2024 Spec Interim Update – Permit Rating Example
This tutorial demonstrates the provisions for LRFR evaluation of permit vehicle loading as specified in the MBE 3rd Edition with 2024 interims. A multi-span steel superstructure is used to illustrate several aspects of the new provisions. The process for permit vehicle loading is similar for all line girder, 3D, and truss analysis methods.
Truss Tutorial | Truss Gusset Plate Example
This tutorial demonstrates the provisions for LRFR evaluation of gusset plate compressive resistance as specified in the MBE 3rd Edition with 2024 interims.
