Pad Foundation Design

Description
EUROCODE 2&7

Precision:

Input- Insert the dimensions of the foundation and the column cross-section, the loads with their respective safety factors, the material properties and the groundwater level-only if it's applicable.

INERT VALUE & TICK THE BOX if the ground water table is at a depth less than the width of the foundation from the base of the foundation. Insert a or b values if the GWL is above or below the base of the foundation, respectively. 		Pad footing

Output results - This will calculate the preliminary sizing (length) in the section table and design a pad foundation for flexure and shear in the tables below from the design input data in the table above.
