Special concrete shear wall design.

Hybrid precast concrete walls use a combination of mild steel bars and high strength unbonded posttensioning steel strands for lateral resistance across horizontal joints. In the concrete shear wall program walls are grouped for design into wall design groups. One of the main structural parts of a building structure is the shear wall. Seismic design of special reinforced masonry shear walls.

Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. A guide for practicing engineers the basic structural elements of an earthquake resistant building are diaphragms vertical framing elements and the foundation. Code ap proval of the hybrid precast concrete wall system as a special reinforced concrete shear wall for moderate and high. In reinforced concrete buildings the vertical elements are usually either moment resisting frames or.

A wall design group can consist of a single wall or multiple walls. To assign wall design groups do the following. 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. 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.

The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. 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.
