Deflection limitation is studied and the slenderness limits are redefined at the load level that satisfies both the maximum crack width and the stresses in materials limitations.
37), which provides the L/d condition that fulfils the deflection limitation, is associated to a loading situation ([M.
1] does not ensure the fulfilment of the deflection limitation.
This paper presents a discussion about the limits of the different SLS, starting from the requirements at a cross-section level to end up with the deflection limitation.
A formulation to calculate the L/d ratio that fulfils the deflection limitation for an FRP RC element is provided.
In a first stage, the optimal depth of the section will be calculated to comply with the crack width limitation and the deflection limitation.
First, the overall height of the beam that fulfils the maximum crack width and the deflection limitations is calculated.
