1.8m SCREEN WALL FOUNDATION DESIGN

I have a screen wall which I need to design the foundations for. I can get so far but I think I am going wrong. We have issued the drawing already and my seniors are saying it's fine, but I'm a graduate and need to build up my design folder so I know how to do these designs in the future..The screen wall is a solid brick, 1.8m high, 0.215m thick...bearing pressure 100kN/m². Our drawing states 600mm wide, 900mm deep

Screen Wall
0.215x1.8x1=0.387m³ x 2250/100 = 8.7kN/m
Wind Load
1.6kN/m²x1.8x0.9= 2.6kNm
Eccentricity
M/N = 2.6kNm/8.7 = 0.29
P= 2N/BY = 2x8.7/0.03 = 580? This figure doesn't seem right? I'm expecting this to be more towards the bearing pressure figure?

Am I making much sense?

All I'm after is knowing how wide the footing needs to be. We don't want mesh.

Any help would be appreciated.

Thanks.

Will

In your work you normally will have to meet some structural codes.

Since masonry, and a foundation in concrete, you need to identify typically those addressing masonry structures, concrete structures, and foundations. Then you need to identify the clauses affecting your structure. Use of the science of construction normally won't be in conflict with what the code states, the codes simply use to introduce some specifics that ensure that the structure will be adequate for the intent.

You have simple methods of design for masonry structures and concrete -for eample- in the CRC engingeering handbook, but it is better to use the guide of the codes vigent in your area from which you may be able -if wanting- to create templates for different kinds of structural problems.
