Determine the required reinforcement to support the applied loading. Given: D- 151 kip L- 150 kip b-24 in. 456kp 90ih h- 90 in. - 4000 psi 1,- 60,000 psi - 22 ft 6 in. Support length: 18 in. at reaction Loads are located at third span and are applied over a bearing length of 18 in. 16 in Elevaton Secton A Fig. El.I-Deep beam geometry. Use the following strut and tie model geometry: Sketch the initial strut-and-tie model visualizing the force flow in the beam (Fig. E1.2). The dashed lines represent the compression elements, the solid line the tension element, and the dimensionless full round cireles represent the nodes-intersection of struts and ties. Because of the short distance between the ap- plied loads and supports, only a single compression strut is used between the applied load and the closest support. A tie is required at the bottom to maintain equilibrium. 456 kip - 456 kip 90 in. 90 in. 90 in. 90 in. 16 in. 3@ 90 in. = 270 in. 16 in. R, = 456 kip R= 456 kip Assume the distance from the top of the beam to the center of nodal zones N2 and N3 is 5 % inches. Assume the distance from the bottom of the beam to the center of nodal zones N1 and N4 is 7 % inches. Requirements: Compute strut and tie forces. Determine extents of nodal zones. Determine the required reinforcement - tension tie steel and vertical and horizontal steel in the beam.
