To safeguard against differential settlement :- (a) Abutments should be sufficiently strong to resist the thrust of arch due to self- weight and superimposed loads. For abutments of ample size – segment arch is strongest For smaller size of supports- semi-circular / pointed arch is used Semi-circular arch is strongest and exerts no thrust on abutments and piers. (b) Whatever may be the shape of arch, it should be symmetrical to avoid differential settlement of support. - Study24x7
