CFVR0940 - In-Plane Shear Calculation – ACI 349-01 Wall - seismic/non-seismic
Design of reinforcement for in-plane shear and membrane forces
To investigate the design of reinforcement for in-plane shear and membrane forces for ACI 349-01, a simple 5 ft x 25 ft x 1 ft wall model was used.
The 5-element model consists of Shell43 elements. Vertical and lateral loads were applied at nodes 3 and 8.
The wall is restrained at nodes 1 and 2 at the base of the model. Node 1 is restrained in the x, y, and z directions for translation as well as rotation in the x and z directions.
Node 2 is restrained in the y and z directions for translation as well as rotation in the x and z directions.
Element types used in the model: SHELL43 Needed CivilFEM Modules: |
