Read MoreA simply supported beam (Figure) with a span of L=20ft is subjected to a uniform service load of 1200 lb/ft, including self weight, and a live load of 900 lb/ft. Determine the maximum factored...

Read MoreFor the simply supported beam of Figure 1, determine the uniformly distributed load, q, at which the flexural crack forms. The beam has a length L=7m, and f’c=25Mpa. Figure 1: Cross-section of Con...

Read MoreCalculate the vertical deflection of the beam (magnitude and direction) at the midpoint of the central span (point A) Solution Use virtual work method: Virtual Structure From Equilibrium: Shea...

Read MoreTruss and cable elements are defined by their ability to carry solely axial loads. Nonetheless, since cables have no stiffness when loaded in compression, they function only in tension. Moreover,...

Read MoreBased on Figure 1, we get: where: In matrix form, the above can be re-written as: Example Figure 2: Two Springs in Series - Example Calculate k1, δ2, and f3. Solution Ba...
