Deflection of Concrete Shear Walls
Deflection of Concrete Shear Walls
(OP)
How do most of you guys compute deflections for concrete shear walls?
The things I am particularly curious about is how you account for:
- Shear Deflection
- Reductions in stiffness after tensile cracking has occured.
- Non-linear behavior of the wall.
Obviously for low, squat shear walls, deflection is most likely not a design consideration, but at some point it must become necessary the get a fairly accurate representation of the deflection.

Otherwise, with a flexible diaphragm, and a short stubby wall, I would have to agree.

I will quote 4 references in PCI Jurnal of the times I was buying this kind of info:
A design procedure for partially prestressed concrete beams based on strength and serviceability, Inomata, PCI JR 266
Creep and shrinkage haracterization for analyzing Prestressed concrete structures, Bazant&Panula, PCI Jurnal May-June 1980
Prestress Loss and Deflection of Precast Concrete Members, Tadros, Ghali, Meyer, PCI JR 308.
Serviceability design of continuous prestressed concrete structures. Elbadry-Ghali.
This last is maybe the best for the concepts to be implemented when accounting for deflections in PC elements.
I think it was this that had a DOS program author Ghali sent to me for free from Calgary, Alberta, Canada, thanks again for that, was a nice program.
Then the PCI Handbook, I have th 4th edition, treats in chapter 3 the cases with stiffness reduction in ACI way, but at least you can easilty follow the (to PCI) relevant steps.
