Crushing of arch ;- To prevent crushing of arch material which occurs when thrust at some point of arch creates the safe crushing strength of material, points considered are:- (a) Size of voussoirs should be adequate to resist anticipated thrust. (b) For small spans , thickness at arch ring is kept uniform from crown to springing. Thickness of ring = 1 12 * span Or thickness = 20 cm for span upto 1.5 m = 30 cm for span between 1.5m to 4m = 40 cm for span between 4m to 7.5 m (c) For large spans (> 7 cm) , thickness of arch ring may be increased at springing by about 20% to thickness at crown. (d) Only first class blocks should be used and for large spans arches may be strengthened by steel reinforced so that safe crushing strength is not exceeded. - Study24x7
