Reinforced concrete shear wall analysis and design.
Perforated concrete shear wall design.
The perforated design method assumes that all openings in the shear wall are able to transfer the loads from around the opening to full length segments.
The proposed design guidelines support the u s.
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.
Special shear wall ibc.
Wdf perforated shear wall design created date.
Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads.
Uplift forces along the base of the wall due to story shear forces.
Percent full height sheathing 4 ft 4 ft 16 ft x 100 50.
The aspect ratios in table 4 3 4 above are applicable for the perforated design method as well.

Configuration b considers a condition where there is blocking between joists e g.
Code ap proval of the hybrid precast concrete wall system as a special reinforced concrete shear wall for moderate and high.
The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14.
Concrete diaphragm in plane shear design based on aci 318 19.
It uses a graphical interface that enables the user to easily generate complex wall models.
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.
Note that they do not include some detailing that is required for items such as the uniform uplift force on the bottom plate of all perforated shear walls or the perforated shear walls with osb sheathing on both sides.
This means that the full length of the wall including segments with openings can be included in the lateral force resisting system.
The tables below show the shear wall specification for the walls in the example in a typical format.
Graphical user interface is provided for.

Hybrid precast concrete walls use a combination of mild steel bars and high strength unbonded posttensioning steel strands for lateral resistance across horizontal joints.
