- •
A numerical iterative procedure for the collapse analysis of circular and pointed masonry arches is developed.
- •
Some classes of collapse mechanisms of pointed arches are identified, depending on the geometrical parameters.
- •
Minimum thickness for circular and pointed arches is evaluated in presence of vertical and horizontal loads.
- •
A probabilistic sensitivity analysis on the lateral load multiplier is carried out by varying the geometrical parameters of the circular and pointed arch.
