3 clear rather than the designed 2 clear.

Concrete shear wall section detail.

Bending strengthof the section has been reduced by about 15 shear strengthat wall base has been reduced by about 14. Each of the exterior walls on all four sides of the building and all interior walls designed as shear walls must have at least one 2 ft 610 mm minimum section of wall identified as a shear segment to resist the high lateral loads. Wall section details. Joist beam connections.

Strength reduced from 136 7 to 116 8 in kips. Precast concrete shear wall panels provide a lateral load resisting system when combined with the diaphragm action of the floor construction. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars. Band joist support beam.

Longer shear segments are more effective and are recommended where possible or required by 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. Concrete shear walls are reinforced with both horizontal and vertical reinforcement figure 4. The effectiveness of precast concrete shear walls is largely dependent on the panel to panel connections.

In some cases precast panels are used as formwork for cast in place concrete. Footings foundation walls. Precast concrete shear wall panels are used to provide lateral load resisting system when combined with diaphragm action of the floor construction. Band joist bottom plate shear.

3500 psi concrete 5 10. Typical load bearing wall units include solid wall panels and window wall and spandrel panels. A reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement. Vertical shear walls and shear wall components.
