It has been shown that the two methods result in very similar bending moment and shear values (Breyer et. This was supremely efficient because we were able to avoid the need to assemble the tables under the slab vanes. He determined that the tensile reinforcement ratio and the span-to-depth ratio had the greatest impact on the shear strength [3]. Soffits are key construction elements—they cover the underside of your roof eaves and exterior porch ceilings. 6x8 beam span chart. For simple span applications without overhangs, as shown in Table 2, note that spans are identical to.
