CFVR7059 - AASHTO10: Shear Checking of a Pipe Section

Shear checking according to AASHTO10 Pipe section.

A steel beam is subjected a uniform load of 1 k/in

The beam has a length of 100 in.
Section material properties: A572Gr50 , Fy = 50 ksi , Fu = 65 ksi
Geometric properties: P 5: OD=5.563 in ; tkwall= 0.258 in . Member property : LV = 50 in

The aim of the example is to obtain the shear criterion according to AASHTO 2010.

Element types used in the model: BEAM3

Needed CivilFEM Modules:
Geotechnical Module
Bridges and Civil Non Linearities Module
Advanced Prestressed Concrete Module

The example can be launched on an educational license.
