Hy-rib and metal lath for concrete, stucco and plaster in roofs, floors, walls, sidings, partitions, ceilings, furring, arches, conduits and tanks .. . hrust per lineal foot may then be figuredbymeans of the following formula: T = WL2R Where W=the load per square foot L=span in feet between supports, andR =rise of the arch in inches. The crown thickness may be determined by the followingformula: C=- 12S Where C = the crown thickness in inchesT = the thrust per lineal foot, andS=the allowable fibre stress per sq. inch. In actual building construction, it is practically impossibleto secure absolutely rigid abutments, unless tie rods are used,and the crown thickness must therefore be materially increasedover the depth determined by the above formula. There is noquestion that an Arched Concrete Floor is capable of carryingconsiderably more load than a flat slab of the same loads on flat slabs, see pages 16 and 17. Our engineers have had wide experience in the designof arched floors under varying conditions. We would beglad to submit our detailed suggestions on the design ofarched floors to meet any particular Arched Hy-Rib Floor in Joseph Bendt Store, Kenosha, Wis., usedin conjunction with reinforced concrete beams.
