BA, Thanks for all of your input. I do not take any of this as criticism as I am merely trying to fully understand and know that what I am designing is structurally adequate plus the qualified engineer that I am under is not of much help. To answer your questions: 1. Elevation of existing...

I also plan to look into the yield line analysis. I have not every looked into this theory. Does anyone have a any good references?

JAE, Do i not have to account for an increase in shear at the slab intersection (assuming the slab is bracing my wall @ 2ft from the top of footing). I was using that assumption and looking at the wall as a single span w/ cantilever. I was assuming a fix condition at the foundation and a support...

BA, The attached sketch should show the dimensions, wall layout, and lateral load for more clarity.http://files.engineering.com/getfile.aspx?folder=03d2f74b-eec4-45e1-94f1-ea3170f585eb&file=image.jpg

Based on constraints of highest point of bulk material and the confined bin width that holds the material, the uniform loading provided in my sketch is based on the triangular distribution reaching the adjacent wall a distance above the top of my concrete wall. In my understanding of other...

hokie66, The load induced on the wall based on the material that I am designing the wall to resist is causing the issue. I am designing the wall to hold a bulk storage material. The issue is where the slab braces the wall. At that intersection I am getting a very large shear force that the wall...

The sketch that I provided was a proposed theory. If it is an applicable theory, do you know of any good references that could point me in the right direction as to know how stiff the beam would have to be to act as a diaphragm (pin) at the top of the wall.

BA.. Attached is a sketch of what I described above. http://files.engineering.com/getfile.aspx?folder=b1311033-f7e0-408a-98f9-5a799ba0a545&file=conc__wall.pdf

In using the non-yielding situation, since I cannot tie the top of the wall to an actual diaphragm, could I possible cast in a really stiff element at the top of the wall (wide flange beam for example) to act as a diaphragm to transfer some of the shear? My wall is spanning between 2 concrete...

BA. How would the stirrups have to be located in the wall? Would additional longitudinal reinforcement work as well? JAE.. Increasing f'c does not give me enough additional shear capacity.

Hello, I am fairly new to concrete design and am trying to determine a way to increase allowable shear resistance in a concrete wall at the intersection of a slab. I am currently dealing with a cantilevered, laterally loaded, wall that has a slab that provides lateral restraint to the wall. My...
