Abstract:
This paper describes an approach to considering the effects of compressive membrane forces in the analysis and design of prestressed and/or reinforced concrete one-way members. The theory of plasticity is applied to find the ultimate load and support reactions for a one-way, restrained-edge slab strip or beam. Modified compression field theory is used in the next step to relate the sectional forces to internal stress, strain, and angle of diagonal cracking at each specified location and to the total deflection. Numerical methods are used in developing a computer program to perform the calculations. The output for 16 one-way slab strips is compared to test results. Reasonable agreements are found for load, deflection, and support reactions at the ultimate load conditions.
