Maximum Length Of Concrete Shear Wall

Wall length is the length of the wall section.

Maximum length of concrete shear wall.

Wood structural panel unblocked 3 1. Spacing of vertical reinforcement reduced to 48 inches. Wall length 18 ft. Reinforced shear wall 7 3 2 5.

Reinforced wall with prescriptive reinforcement of detailed plain shear wall. Design for shear max. Reinforced shear wall 7 3 2 6. One of the main structural parts of a building structure is the shear wall.

Maximum shear wall dimension ratios. Wood frame shear wall and diaphragm design ricky mclain ms pe se. Shear walls with multiple openings and no headers. A length to height ratio of 1.

Maximum spacing of vertical and horizontal reinforcement is min 1 3 length of. 4 bars at 16in. If you leave this entry blank it will be filled in for you by the program. On centers in each face as vertical 5 18 in horizontal reinforcement.

Length of wall per sdpws section 4 3 5 2 anchor bolts or nails typical boundary member typical boundary member 2 min. Shear wall is a vertical structural element used to resist the lateral forces that are usually due to the wind and seismic loads. In this example the maximum spacing of 25 ft 7 62 m governs over the length to height ratio. 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.
