Maximum Length Of Concrete Shear Wall

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 of concrete shear wall.

A length to height ratio of 1. Type maximum length width ratio for an 84 x 34 diaphragm the aspect ratio is 2 5 3. On centers in each face as horizontal 4 16 in 1. If you leave this entry blank it will be filled in for you by the program.

Length of wall per sdpws section 4 3 5 2 anchor bolts or nails typical boundary member typical boundary member 2 min. Reinforced wall with prescriptive reinforcement of detailed plain shear wall. 4 bars at 16in. One of the main structural parts of a building structure is the shear wall.

In this example the maximum spacing of 25 ft 7 62 m governs over the length to height ratio. Design for shear max. Wall length 18 ft.

The program considers the effective shear length of the wall to be 0 8 wall length. Maximum length is the overall wall length offset. Spacing of vertical reinforcement reduced to 48 inches. 5 bars at 18in.

Maximum shear wall dimension ratios. Wood structural panel unblocked 3 1. 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. Reinforced shear wall 7 3 2 6.

Shear wall is a vertical structural element used to resist the lateral forces that are usually due to the wind and seismic loads. Maximum spacing of vertical and horizontal reinforcement is min 1 3 length of. Diaphragm aspect ratio is ok. On centers in each face as vertical 5 18 in horizontal reinforcement.
