Section 3: Strut-and-Tie Method

Anchor: #i1375687

Structural Analysis

Do not use Strut and Tie Modeling for standard girders and bent caps. Strut and Tie Modeling is appropriate to use when designing footings, dapped beam ends, post-tensioning anchorage zones, deviation diaphragms, bents that use high load bearings, and other special designs.

Design Criteria

For members designed with strut-and-tie, check the calculated shear, using the Service I Load Combination, against the resistance from Equation C5.8.2.2-1.
