ANALYSIS AND DESIGN OF LATERALLY RESTRAINED STRUCTURAL CONCRETE ONE-WAY MEMBERS

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 ship 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 out put for 16 one-way strips is compared to test results. Reasonable agreements are found for load, deflection, and support reactions at the ultimate load conditions.
