WebThe authors had earlier tested a series of very-high-strength concrete wall specimens (fc′ = 100 MPa [14,500 psi]) to investigate the influence on shear strength of several parameters, such as: height-to-length ratios, shear (web) reinforcement ratios in the vertical and horizontal directions, as well as the presence of flanges (boundary ... WebMar 9, 2024 · Suppose the base of the actual roof is measured to be 40 feet. You can set up the following equivalence: base of triangle/base of actual roof = hypotenuse of triangle/hypotenuse of roof. Plugging in the numbers, you get 1/40 = 1.06 /x, where x is the required rafter length. Solving for x, you get x = (40) ( 1.06) = 42.4 feet. http://www.historyofbridges.com/facts-about-bridges/truss-bridge/ song it will be worth it all
