Problem No$\mathrm{.}2$:

A long trench is excavated in clay for the foundation of multistorey building. The sides of the trench are supported with sheet pile walls fixed in place by struts and wales as shown. The properties of soil are:

$r=19\mathrm{.}5k\frac{N}{m^3},c=60,\frac{O}{?}=0$

Determine:

I. Strut loads. The struts are place horizontally at distance $s=5m$ center to center.

$2.$ The maximum bending moment determining the pile wall section.

$3.$ The maximum bending moments for determining the section of the wales.

$4.$ Section Modulus for Sheet Piles and Wales $($ a $l$ l $,=150M\frac{N}{m}22)$
