Foundation Eccentricity for Single-Side Cantilever Parking Shelter

[tmgczb]

As shown in the picture, footing eccentricity towards left side or right side is more favorable?

 

[human909]

If your major overturning loads are gravity then an eccentric footing to the left side makes sense. A free body diagram should demonstrate this. "Common sense" of having your support closer to the centre of your load also should guide your thinking.

If the structure is quite lightweight, not subject to snow loads then the main overturn load may be lateral in which case it is likely easiest to provide something symmetric or close to symmetric.


Optimise the outcome how you wish. But if that answer isn't obvious then experiment and teach yourself.

In desert regions, where wind is heavy, is wind uplift case is more critical for membrane structure?

You need to calculate and see if wind uplift case is more critical .

As shown in the picture, footing eccentricity towards left side or right side is more favorable

Shift the footing to left. If desert region and probably no snow, the following pdf copies will give some idea and however the e eccentricity should be at left.

I have written to AI and ask if any pdf copy for parking sunshade and the followings are the outcome. You can check ur foundation dimensions .
