Reinforced Concrete Shear Wall Design

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.

Reinforced concrete shear wall design.

The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. They support vertical loads and are vulnerable to minor axis bending. A reinforced concrete load bearing shear wall supporting for a four story building. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.

Special reinforced concrete structural walls are walls that have been proportioned and detailed to meet special code requirements for resisting combinations of shear moment and axial force that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. Design of reinforced concrete load bearing shear wall. Reinforced concrete wall is classified as. Aci 318 05 design data.

However these older shear walls were typically designed for combined actions of gravity loads and wind loading. Design of reinforced concrete walls are in many ways like columns. Concrete shear wall design spreadsheet. Concrete shear wall design spreadsheet reinforced concrete design civilweb spreadsheets.

The civilweb concrete shear wall design spreadsheet is a powerful spreadsheet for the design of shear walls in buildings. Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings. Live load at each floor and roof. They often act as primary elements of a structure s lateral stability systems and by doing so are subjected to high in plane bending forces.

Strength reduced from 136 7 to 114 9 in kips. Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted. Plain concrete wall when reinforcement 0 4. Figure 1 reinforced concrete shear wall geometry and loading.

Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. Service load dead load at each floor and roof. P l 25 kips. Reinforced concrete shear wall analysis and design 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.

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. 2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16. P d 40 kips. Reinforced concrete wall is designed as a compression member.
