This document discusses types of arches used in structural analysis and design. It describes three types of arches based on their end conditions: three-hinged, two-hinged, and fixed arches. It also describes two common arch shapes: parabolic and circular arches. The document outlines where arches are used in bridges, buildings, and other structures. It discusses analyzing arches for forces like reactions, bending moments, and horizontal thrust.

8. ARCHES
 An arch looks like curved girder , either a solid rib or braced supported at its
ends and carrying transverse loads which are frequently vertical .
Used in..
1. Railway and highways bridges.
2. Used in buildings to carry loads over doorways, windows etc.,
3.Industries,
4.Also used in aesthetic touch to building.
