Ductility of Prestressed and Partially Prestressed Concrete Beam Sections
D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...
متن کاملForecasting of Shear Strength of Concrete Beam Reinforced with FRP Bar
This study develops a new approach for forecasting shear Strength of concrete beam without stirrups based on the artificial neural networks (ANN). Proposed ANN considers geometric and mechanical properties of cross section and FRP bars, and shear span-depth ratio. The ANN model is constructed from a set of experimental database available in the past literature. Efficiency of the ANN model was c...
متن کاملSize Effect of Shear Failure in Prestressed Concrete Beams
It is shown that the size effect predicted by dimensional analysis of fracture mechanics of failures due to progressive distributed microcracking agrees with the test data existing in the literature better than the presently used strength (ultimate load) criterion, which exhibits no size effect, and better than the linear i!lastic fracture mechanics criterion, which exhibits much too strong a s...
متن کاملParametric Study of Continuous Concrete Beam Prestressed with External Tendon
This paper presents the results of a parametric study of the flexural behavior of continuous concrete members prestressed with external tendons. The behavior at ultimate limit states is evaluated. A nonlinear analysis model, based on the three dimensional finite element method, ANSYS computer program (10.0) was used. The nonlinear material and geometrical analysis were adopted. The results obta...
متن کاملEffect Of Web Reinforcement On Ultimate Strength Of Reinforced Concrete Deep Beam
It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength o...
