!*************************************************************************************! ! TITLE: CFVR0948 - In-Plane Shear Calculation – ACI 349-01 Wall ! SUBTITLE: Design of reinforcement for in-plane shear and membrane forces ! ! DESCRIPTION: To investigate the design of reinforcement for in-plane shear and membrane ! DESCRIPTION: forces for ACI 349-01, a simple 5 ft x 25 ft x 1 ft wall model was used. ! DESCRIPTION: ! DESCRIPTION: The 5-element model consists of Shell43 elements. Vertical and lateral ! DESCRIPTION: loads were applied at nodes 3 and 8. ! DESCRIPTION: ! DESCRIPTION: The wall is restrained at nodes 1 and 2 at the base of the model. ! DESCRIPTION: Node 1 is restrained in the x, y, and z directions for translation as ! DESCRIPTION: well as rotation in the x and z directions. ! DESCRIPTION: ! DESCRIPTION: Node 2 is restrained in the y and z directions for translation as well ! DESCRIPTION: as rotation in the x and z directions. ! DESCRIPTION: ! DESCRIPTION: Check ACI 349-01 Ch.14 (11.3.2.3):If tensile stress exceeds 500 psi, then Vc=0 ! ! ELEMENT TYPE: Shell43 ! MODULES: ! UNITS: BIN ! KEYWORD1: Shell ! KEYWORD2: Shell Vertex !
