| Abstract | ||
| ~ransv~&e openings are sometimes very essential for accommodating utility services in reinforced . . wncrete structures. Most current codes and specifications have no provisions for specific design of reinforced concrete beanis with openings andmbjected to torsion. The object of this research is to develop a nonlinear 3-D finite elements constitutive model for RC. beams with openings ~bjected to torsion by simulate the experimental behavior. A computer program based on finite element method is developed to include the nonlinear material properties of both concreteand steel feinforcement. The output results of the F.E. program are compared and ' verified with the experimental results done by other researchers. The effect of some important parameters such as 'tension stiffening, shear retention paranieters, compressive suength of ' concrete, as well as the opening dimensions, and their locations are studied and investigated. Finally the main results are.summhd. . : | ||
