Abstract:
A 20 ft (6.10 m) span deep beam was designed using the strut-and-tie method according to ACI 318-02 Appendix A. The beam is 20 in. (508 mm) wide and 80 in. (2032 mm) deep and carries two concentrated factored loads, V, of 360 kips (1601 kN) each. Bearing plates of 18 in. x 20 in. (457 mm x 508 mm) are provided at all loading and support locations. The self-weight was not considered in the design. The compressive strength of concrete, fc and the yield strength of the steel reinforcement, fy are taken as 4 ksi (27.6 MPa) and 60 ksi (414 MPa), respectively. A simple strut-and-tie model shown in Fig. (1 b-2) is used in the design. The provided reinforcement for the main tie is 2 layers of 5 #9 (#29 mm) bars. The anchorages of these bars are provided by means of standard 90’ hooks. The reinforcement details are shown in Fig. (1 b-6).
