Special concrete shear wall design.

Let s discuss the concrete shear wall and shear wall design. To incorporate the use of high strength reinforcement into building systems. 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. The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14.

Boundary element is a portion along wall and diaphragm edge including edges of openings strengthened by longitudinal and transverse reinforcement. Together these elements comprise the seismic force resisting system sfrs. A guide for practicing engineers the primary seismic force resisting elements in buildings are horizontal diaphragms vertical framing elements and foundations. Spwall is a program for the analysis and design of reinforced concrete shear walls tilt up walls precast wall and insulate concrete form icf walls.

It uses a graphical interface that enables the user to easily generate complex wall models. Seismic design of special reinforced masonry shear walls. Reinforced concrete shear wall analysis and design. Strength reduced from 136 7 to 116 8 in kips.

The design of concrete shear wall building longitudinal reinforcement for seismic performance has. Another category in shear wall wall design is to determine the area of boundary element. The thickness and the length of the walls are determined as per the design requirements. Structural walls sometimes referred to as shear walls.

Shear strength reduced from 7654 lbs to 6589 lbs. 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. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. Shear wall while also acting as an ex terior curtain wall.

It is a zone in a wall wherein a confinement reinforcement is needed. Astm a706 grade 80 reinforcement with special additional requirements is being used as concrete shear wall longitudinal reinforcement for the 1500 mission street. Shear wall analysis and design spwall software. 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.

The shear wall is a concrete wall constructed from the foundation level to the top of the building. Bending strengthof the section has been reduced by about 15 shear strengthat wall base has been reduced by about 14. 3500 psi concrete 5 10.
