125 and 127. The latter form is generally calledthe spandrel-braced arch. While an arch rib is analogous to abeam, a braced arch is analogous to a truss and hence thehorizontal thrust H cannot be derived by the formula establishedin Art. -jG from the consideration of pure fiexural stresses. Itis… … Fig. 125. The reactions at the supports are resolved into their ver-tical and horizontal components, and, as for the arch rib,V^ = P{i-k), V., = Pk, (I) are the vertical components of the reactions. To find the horizontal component, or horizontal thrust H,similar reasoning to that in Art. 76 will…
