Do we design a raft for one way shear if yes what is the criteria to check one way shear design of raft mat foundation.
Shear wall mat foundation.
X x y y e x e y example a mat foundation is to be design by the conventional method rigid method for the loadings shown in fig.
It is also termed as a box mat foundation.
Thick structural reinforced concrete shear wall is to be supported by a strip footing.
Reinforced concrete shear wall foundation strip footing analysis and design a 12 in.
In the cellular mat foundation the structures of boxes are formed and walls of every box act as beams.
A mat foundation is a thick reinforced concrete slab supporting arrangements of columns or walls in a row or rows and transmitting the loads to the soil.
This type of foundation is suitable for loose soil.
The shear wall is a concrete wall constructed from the foundation level to the top of the building.
A mat need not have columns and walls modeled above.
Typically shear walls are constructed as lift core walls and around the staircases.

In particular i am talking about large mats that support multiple shear walls and columns and are not easily divided up visualized in any particular grid.
Does anyone have any good references for designing for shear in mat foundations.
Usually we provide a thickness such that shear reinforcement is not required.
The thickness and the length of the walls are determined as per the design requirements.
The shear wall carries service dead and live loads of 10 kips ft and 12 5 kips ft respectively.
It is used to support storage tanks industrial equipment silos chimneys and various tower structures.
The walls are connected by slabs at the top and bottom.
Otherwise the supports above rather than the soil springs below could resist some lateral moment and shear.

I usually count d on each side of the shear wall assemblage.
