Abstract
Arches have been known for thousands years. Pharaohs in
ancient Egypt used them widely in their temples. The wide
spread of such type of structures is due to its beautiful
architectural appearance,
its economy and its inherent
capacity in resisting loads due to its form.
Making the arch as a funicular curve as possible by
considering practical requirements, will result in
minimizing the straining actions acting on the arch and thus
getting its maximum structural advantages.
The shape of the arch may adopt one of the following
two geometries
1- One continuous curve such as circular, parabolic, or
catenary arches.
2- A combination of any two curves.
The investigation in the present study will be limited
to the first type only Arches may be stiffened by means of a truss, this
structural combination is so called” TRUSSED ARCH The
main profits gained from the trussed arches are:-.
