! SUBTITLE: Check 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 06, a simple 5 ft x 25 ft x 1 ft slab 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:
