Foundation Design

A square foundation $($B xx B$)$ has to be constructed in a site in downtown San Diego that includes

interbedded layers of sand and clay $($for bearing capacity calculations we conservatively assume c$^(\text{'})=0).$

Water table is located at $150$ ft below ground surface.

Given:

Unit weight of the soil$=118$ pcf

phi$^(\text{'})=33$deg.

Foundation Embedment depth $($D$\_($f$))=3$ft

Soil Average Elastic Modulus $($E$\_($s$))=200$ksf

Allowable settlement$=1\mathrm{.}5$ in

The factored SLS $($Strength Limit State$)$ and non$-$factored vertical load, shear load, and bending moment

are attached.

Column width $($c$)=18$ in

Requested:

A foundation engineering report that at least includes:

$-$Table of contents $(5\%)($One Page$)$

$-$Assumptions $(5\%)($One Page$)$

$-$Bearing capacity curves $($using Terzaghi approach$)$ for general shear failure and settlement $(15\%)($One

Page$)$

$-$Explain the suggested footing size under the given loads $(15\%)($One Page$)$

$-$Check against sliding $(20\%)($One$/$Two Pages$)$

$-$Structural design of the footing $($includes thickness of the footing and steel rebars and their spacing$)$

$(25\%)($Two$/$Three Pages$)$

$-$Summary that includes a sketch of the footing with its reinforcements $(15\%)($One Page$)$
