Maximum spacing of vertical and horizontal reinforcement is min 1 3 length of.

Maximum length of concrete shear wall.

Spacing of vertical reinforcement reduced to 48 inches. 5 bars at 18in. On centers in each face as horizontal 4 16 in 1. Reinforced shear wall 7 3 2 5.

One of the main structural parts of a building structure is the shear wall. Maximum shear wall dimension ratios. Length of wall per sdpws section 4 3 5 2 anchor bolts or nails typical boundary member typical boundary member 2 min. Type maximum length width ratio for an 84 x 34 diaphragm the aspect ratio is 2 5 3.

1 which corresponds to 1 x 20 ft 30 ft 9 14 m or control joints spaced every 25 ft 7 62 m. In this example the maximum spacing of 25 ft 7 62 m governs over the length to height ratio. Enter the length to be used in the analysis of the particular wall section. The program considers the effective shear length of the wall to be 0 8 wall length.

Wall length is the length of the wall section. Shear walls with multiple openings and no headers. On centers in each face as vertical 5 18 in horizontal reinforcement. If you leave this entry blank it will be filled in for you by the program.

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. 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. Design for shear max.

Maximum length is the overall wall length offset. Wood frame shear wall and diaphragm design ricky mclain ms pe se. Reinforced wall with prescriptive reinforcement of detailed plain shear wall. Shear wall is a vertical structural element used to resist the lateral forces that are usually due to the wind and seismic loads.
