Shear due to loads v u design shear capacity ϕv n where ϕ 0 75 design shear capacity ϕv n design shear strength of concrete ϕv c design shear strength of reinforcement ϕv s ϕv n ϕv c ϕv s therefore v u ϕv c ϕv s shear force that concrete can resist without web reinforcement v c. Maximum spacing of vertical and horizontal reinforcement is min 1 3 length of.

If you leave this entry blank it will be filled in for you by the program. Wall length is the length of the wall section. Wood structural panel unblocked 3 1. Shear wall is a vertical structural element used to resist the lateral forces that are usually due to the wind and seismic loads.

These forces are acting in the plane of the wall by the cantilever action where the bending deformation governs if slender walls are concern and a truss action for short walls where the. The program considers the effective shear length of the wall to be 0 8 wall length. On centers in each face as vertical 5 18 in horizontal reinforcement. This module allows the design of concrete shear walls including multi story walls with no openings but with up to five levels of differing length height and thickness.

Maximum length is the overall wall length offset. Wall length 18 ft. Reinforced wall with prescriptive reinforcement of detailed plain shear wall. Reinforced shear wall 7 3 2 6.
