    Crushing Strength of Reinforced Concrete Membranes

    Date: 9/1/1988. Abstract: Develops a methodology for the determination of the crushing strength of reinforced concrete membranes with two-way orthogonal reinforcement on the basis of theoretical considerations and experimental results. It differs from previous work in this area with respect to two principal features
