Special Concrete Shear Wall Design Example

Two weeks ago i had the chance to present to the young members group of the structural engineering association of metro washington on the topic of multi story light frame shear wall design.

Special concrete shear wall design example.

Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. Shear strength reduced from 7654 lbs to 6589 lbs. A guide for practicing engineers nist gcr 14 917 31 prepared by the applied technology council for the national institute of standards and technology gaithersburg md. H 15 ft.

Aci 318 05 design data. The design process is illustrated with examples. It uses a graphical interface that enables the user to easily generate complex wall models. Reinforced concrete shear wall analysis and design 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.

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. 3500 psi concrete 5 10. Wood structural panel wood frame shear walls shall be designed and constructed in accordance with af pa sdpws. Both the design for overturning and the design for shear are explained.

V 4 75 kips 3rd floor. V 3 50 kips. Strength reduced from 136 7 to 116 8 in kips. A guide for practicing engineers the basic structural elements of an earthquake resistant building are diaphragms vertical framing elements and the foundation.

H 10 in. Seismic design of cast in place concrete special structural walls and coupling beams. V r 100 kips. With all of the large firms in the d c.

Shear wall analysis and design spwall software. In reinforced concrete buildings the vertical elements are usually either moment resisting frames or. 3 clear rather than the designed 2 clear. Bending strengthof the section has been reduced by about 15 shear strengthat wall base has been reduced by about 14.

Wood structural panel shear walls are permitted to resist horizontal forces using the allowable. The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. Design of reinforced concrete non load bearing shear wall. Seismic design of special reinforced masonry shear walls.

V 2 25 kips. L w 18 ft. 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.
