Compute horizontal reaction in two-hinged arch by the method of least work. Write strain energy stored in two-hinged arch during deformation.

Analyse two-hinged arch for external loading. Compute reactions developed in two hinged arch due to temperature loading.

In the early part of the nineteenth century, three-hinged arches were commonly used for the long span structures as the analysis of such arches could be done with confidence. However, with the development in structural analysis, for long span structures starting from late nineteenth century engineers adopted two-hinged and hingeless arches.

Two-hinged arch is the statically indeterminate structure to degree one. Usually, the horizontal reaction is treated as the redundant and is evaluated by the method of least work. In this lesson, the analysis of two-hinged arches is discussed and few problems are solved to illustrate the procedure for calculating the internal forces.

In the case of two-hinged arch, we have four unknown reactions, but there are only three equations of equilibrium available. Hence, the degree of statical indeterminacy is one for two- hinged arch. The unknown redundant reaction H b is calculated by noting that the horizontal displacement of hinge B is zero. In general the horizontal reaction in the two hinged arch is evaluated by straightforward application of the theorem of least work see module 1, lesson 4 , which states that the partial derivative of the strain energy of a statically indeterminate structure with respect to statically indeterminate action should vanish.

Hence to obtain, horizontal reaction, one must develop an expression for strain energy. Typically, any section of the arch vide Fig Bestsellers Editors' Picks All Ebooks. Explore Audiobooks.
