Reinforced concrete working stress design
WebA reinforced concrete beam has a width of 280 mm and an effective depth of 520 mm. It is reinforced for tension only with 5-28 mm diameter bars. Material strengths are f’c = 21 MPa and fs = 128 MPa. Assume n = 9 and use working stress design. WebThe design of reinforced concrete structural members may be done by two different methods. One, called working stress design (WSD), is based on the straight-line distribution of compressive stress in the concrete (Fig. 1), covered in Appendix B by ACI 318. This method was the prevalent

WebSep 7, 2024 · Assumptions of working Stress Method. 1. At any cross section,plane sections before bending remains plane after bending. 2. All tensile stresses are taken up by reinforcement and none by concrete,except otherwise specially permitted. 3. stress-strain relationship of steel and concrete under working load is a straight line. Web“From the early 1900s until the early 1960s, nearly all reinforced concrete design in the United States was performed by the working-stress design method (also called allowable-stress design or straight-line design). In this method, frequently referred to as WSD, the dead and live loads to be supported, called working loads or service loads,
