Ordinary Reinforced Concrete Shear Wall

5 bars required by.

Ordinary reinforced concrete shear wall.

Two possible seismic resisting systems using reinforced concrete are moment frames and shear walls. Stack exchange network consists of 176 q a communities including stack overflow. Although such walls contain some reinforcement the msjc also mandates prescriptive reinforcement to ensure a minimum level of performance during a design level earthquake. The continuous vertical bar required beside an opening is permitted to substitute for one of the two no.

Provisionschapter 4 presents design coefficients and system limitations for various seismic design categories. The changes are a result of the unsatisfactory performance of many shear walls in the chile earthquake of 2010 and the christchurch new zealand earthquake of 2011. Precast walls can be used however they will not be addressed in detail in this lecture. Vertical reinforcement of at least 0 20 square inch 129 mm 2 in cross sectional area shall be provided continuously from support to support at each corner at each side of each opening and at the ends of walls.

The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. Figure 1 reinforced concrete shear wall geometry and loading. Detailed plain concrete shear walls are walls conforming to the requirements for ordinary plain concrete shear walls and shall have reinforcement as follows. The design process is illustrated with examples.

In asce 7 10 table 12 2 1 two types of shear walls can be used ordinary reinforced concrete shear walls and special reinforced concrete shear walls what is it the difference between these walls. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. 9 2 1 5 intermediate precast shear walls. A structural reinforced concrete shear wall in a 5 story building provides lateral and gravity load resistance for the applied load as shown in the figure below.

Both the design for overturning and the design for shear are explained. 21 1 of aci 318 for ordinary reinforced concrete structural walls. Ordinary reinforced concrete shear walls shall satisfy the requirements of sec. Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings.
