Reinforced Concrete Shear Wall Detail

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.

Reinforced concrete shear wall detail.

There are three types of action a reinforced concrete wall can be subjected to. Strength reduced from 136 7 to 114 9 in kips. Sheet steel and steel backed shear panels in the place of structural plywood. Useable area was created for actors c.

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. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. The base is divided into two parts the heel and toe. Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.

However these older shear walls were typically designed for combined actions of gravity loads and wind loading. The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. Shear wall buildings in romania whe report 78 have lightly reinforced walls with one layer of 2 mm diameter vertical bars and 8 mm horizontal bars. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.

Concrete shear wall construction. The action to which walls are most vulnerable is bending and this guidance note principally addresses this form of stress. Shear walls are typically light framed or braced wooden walls with shear panels reinforced concrete walls reinforced masonry walls or steel plates. Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings.

Sonry shear walls integrated with the spatial expression of the interior spaces and a mixture of reinforced concrete slabs and beams and steel and composite metal deck floor framing all supported on new shallow reinforced concrete foundations and grade beams. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used. The reinforcement spacing varies from 50 mm to 250 mm for walls in the longitudinal and transverse direction respectively. Axial forces minor axis bending and shear and major axis bending and shear.
