Foundation Design Problem: Spread Footing for a Residential Building

Problem Statement:

You are tasked with designing a spread footing foundation for a $3-$story residential building. The building is to be constructed in the Hammond area, Indiana. Consider typical soil conditions and climate factors for this region in your assumptions, particularly for frost depth. Here are the following characteristics:

Dead Load per Column $($including self$-$weight$)$: last two digits of ID$)$

Live Load per Column: $200+(2\backslash$times last two digits of student ID$)$ kN

Soil Profile: Medium$-$dense sandy soil with a groundwater table located $3$ m below ground level.

Allowable Bearing Capacity of Soil $($qa$)$: $150+(2$ last two digits of student ID$)k\frac{N}{m^2}$

Soil Unit Weight $($ last two digits of student ID$)k\frac{N}{m^3}$

Concrete Unit Weight $(c)$:$24k\frac{N}{m^3}$

Footing Thickness $(t)$: $0\mathrm{.}5$ m

last two digits of student ID$)$

Cc: last two digits of student ID$)$

Cr: Cc$/10$

Building Layout:

Structure Dimensions:

Width: $12$ meters

Length: $18$ meters

Story Height: $3$ meters per floor

Column Layout:

Grid Spacing: Columns are spaced at $6$ meters center$-$to$-$center in both directions.

Column Locations: There are four rows along the length $(18m)$ and three rows along the width $(12m),$ resulting in a total of $12$ columns.

Column Size: Each column has a cross$-$sectional dimension of $400mm400$ mm $.$

Submission Requirements:

$>$ Manual calculation

Calculations for ULS: Bearing capacity calculations, including load and safety factors.
