Question

What are the principles of analysing a fixed arch?

Answer 1

Answer:

Fixed arches restrict the horizontal, vertical or rotational movement at its two ends, so a fixed arch is an indeterminate structure.Eddy's theorem states that “ The bending moment at any section of an arch is proportional to the vertical intercept between the linear arch (or theoretical arch) and the centre line of the actual arch.” *Parabolic arches are preferably to carry distributed loads.
