Eurocode 2 has two alternative methods for checking
deflection, either a limiting span-to-depth ratio may be used or
the theoretical deflection can be assessed using the expressions
given in the Code.
The latter is dealt with in detail in 'How
to design concrete structures using Eurocode 2: Deflection
Calculations'. The span-to-depth ratios should ensure that
deflection is limited to span/250 and this is the procedure
presented in the flow chart below.
