Maximum Length Of Concrete Shear Wall

Wall length is the length of the wall section.

Maximum length of concrete shear wall.

A length to height ratio of 1. Maximum length is the overall wall length offset. If you leave this entry blank it will be filled in for you by the program. 4 bars at 16in.

Type maximum length width ratio for an 84 x 34 diaphragm the aspect ratio is 2 5 3. Spacing of vertical reinforcement reduced to 48 inches. Length of wall per sdpws section 4 3 5 2 anchor bolts or nails typical boundary member typical boundary member 2 min. 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.

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. In this example the maximum spacing of 25 ft 7 62 m governs over the length to height ratio. Shear wall is a vertical structural element used to resist the lateral forces that are usually due to the wind and seismic loads. On centers in each face as vertical 5 18 in horizontal reinforcement.
