In-Depth Information
The model proposed in EN1168 to evaluate the shear capacity in regions
uncracked in bending provides a better approximation for HCS with web shear
tension failures (S).
The HCS previously precracked in
exure showed an enhanced shear behavior,
and obtain higher safety margins (20
fl
30 %) than those of uncracked HCS.

Use of
bers is a possible solution to overcome shear failure since
bers are
capable of increasing element strength to its full
fl
exural capacity, thus atten-
uating Kani
'
s valley.
