Please explain the question
in detail (please solve it in euro codes):
An open rectangular concrete
tank sits at ground level and must be designed to contain sludge to an
operational depth 0.7m below the top of the walls. The internal dimension of
the tank is: L x B x H is 7x7x6 metres. The base is 500mm deep and is assumed
to provide a continuous edge restraint to the walls. The strength class of the
concrete is C35/45 and cement containing 30% GGBS is specified. The tank will
be poured in winter and formwork is not specified. Assume cover to
reinforcement is 50mm. Your design must include 1. Structural design of the
walls and base of the tank. 2. Check the adequacy of the wall reinforcement for
early-age and long-term cracking. State all design assumptions that you make
and reference all design formulas. 3. Produce a neat hand drawn sketch of your
tank to show dimensions and the required reinforcement. 4. Discuss the main
issues relating to the construction of a liquid retaining tank such as the one
you have designed, with particular emphasis on minimising crack formation(300
words).
