Web13 Apr 2024 · Those two stresses are computed independently. The combined stress from the axial direct stress and the bending stress is unsurprisingly called Combined Stress on the Beam Tool. Refer to the definitions below. Referring to Wenlong's excellent diagram using tension, the Maximum Combined stress will be reported from the top of the beam. WebTesting of many reinforced concrete beams has shown that the average stress within the compressive zone is 0.85β 1 fc ', and the resultant location is β 1 c /2 from the face of the concrete beam, as shown in Figure 5.23a. The coefficient β 1 ranges from 0.85 for fc ' ≤ 4000 psi, to 0.65 for fc ' ≥ 8000 psi (Figure 5.24).
