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.
Special reinforced concrete shear wall design.
Area it wasn t a big surprise to find out that only about one third of the group had experience with light frame shear wall design.
Specifically is monolithic emulation required for ipsw or is that the difference between the two systems.
What is the difference in detailing for intermediate precast shear walls ipsw vs special reinforced concrete walls srcw made from precast elements.
Be alert to unique issues that make design of special reinforced masonry shear walls different from other.
Be familiar with the special reinforced masonry shear wall design process 2.
The requirements of this section apply to special reinforced concrete structural walls serving as part of the earthquake force resisting system.

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.
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 with all of the large firms in the d c.
Nist technical brief no.

Based on aci 18 10 4 1 nominal shear strength v n of structural walls is not to exceed vn acv c f c t fy where c is a coefficient defining the relative contribution of concrete strength to wall strength given as follows.
A guide for practicing engineers learning objectives participants will 1.
Reinforced concrete shear wall analysis and 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.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
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.
My understanding is that srcw requires monolithic emulation design but ipsw is primarily for typical large panel jointed precast walls which are coupled together for sharing dead load to resist overturning but no special reinforcement.
Strength reduced from 136 7 to 114 9 in kips.
