THRUST LINE METHOD OF ANALYSIS OF MASONRY ARCHES Static Approach- The line containing all the points where the stress resulted at every section of the arch is called thrust line. *The arch is safe when line of thrust is found to total inside the thickness of the masonry.A classic analysis method using this result involves the use of funicular polygon. This is a graphic method to construct the line of thrust for arches. If the arch is subjected only to vertical loads, then the horizontal component of thrust is constant throughout the whole arch. Nevertheless, the value of this component and its position at the start / end of the element are unknown. Thus the method must be iterative. Maximum Thrust- The maximum thrust case is thrust line, or zone of thrust, which takes the intrados once near the crown and the extrados near each springing. This pattern is the response the arch makes to abutments which squeeze together. Linear Arch / Theoretical Arch / Line Of Thrust When arch is subjected to given system of loading, the arch shape which follows the shape of the BM diagram for a beam of some span as that of the acrh and subjected to some loading as that in the arch is known as linear arch. *The line of thrust of a portable arch is funicular polygon. Eddy’s Theorem- In an arch, BM at any point = horizontal thrust * vertical distance between line of thrust and centre line of arch (BM at any section of an arch is proportional to the ordinate/intercept between the given arch and the linear arch.) - Study24x7
