Maximum length of concrete shear wall.

Reinforced wall with prescriptive reinforcement of detailed plain shear wall. Wall length 18 ft. Spacing of vertical reinforcement reduced to 48 inches. The program considers the effective shear length of the wall to be 0 8 wall length.

Reinforced shear wall 7 3 2 6. On centers in each face as horizontal 4 16 in 1. Enter the length to be used in the analysis of the particular wall section. Length of wall per sdpws section 4 3 5 2 anchor bolts or nails typical boundary member typical boundary member 2 min.

Diaphragm aspect ratio is ok. 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. One of the main structural parts of a building structure is the shear wall. 1 which corresponds to 1 x 20 ft 30 ft 9 14 m or control joints spaced every 25 ft 7 62 m.

Reinforced shear wall 7 3 2 5. 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 spacing of vertical and horizontal reinforcement is min 1 3 length of. Maximum length is the overall wall length offset.
