Abstract
An analysis of masonry arches where collapse is assumed to occur by the hinging of voussoirs upon each other is made. The behaviour of the arch material is assumed to be such that the plastic theory is valid. Certain aspects related to the properties So far the approach by of the line of thrust are clarif led. writers has been based on the conventional view that the 1 ine of It is shown that pressure is tangential to the line of thrust. this is not the case in general. Definitions are given on what is meant by "line of thrust" and line of pressure in arches and the analysis is done in the light of the meanings attached to these The analysis is done for the case of a semi—circular terms . masonry arch under an infinite overburden pressure and the results obtained are compared to ones obtained by Irvine (4) whose approach was based on the conventional views of the line of thrust and It is shown that there is a significant difference in pressure . results with the two approaches. The analysis is repeated for the case of masonry arches of a general angle of embrace. The results obtained give critical values of voussoir thicknesses for the stability and the safe dimensioning of masonry arches.
