On the basis of the observed failure mode, a mechanical model was developed to predict the ultimate shear resistance of SCS deep beams after critical diagonal cracking. The analytical and numerical results have been compared to the experimental findings, and good agreement was in general obtained. The shear strength of SC beams increased with larger longitudinal reinforcement ratio, and decreased with larger shear span-to-depth ratio. The numerical modeling approach is recommended for future research and design of specific SC wall configurations to resist design basis missiles. This paper presents the results of experimental investigations conducted in Japan and in the United States to evaluate the pullout (tension) strength and ductility of these lap-splice connections. Extensive discussions and analysis were also carried out to provide information for the development of the analytical models. A numerical model was developed and benchmarked to calculate the flexural capacity of partially composite beams while accounting for slip at the steel-concrete interface. This reveals the complex inter-relationship between the beam length, stud slip capacity, and the minimum level of partially composite action that may be permitted for design. The accuracy of the predictions by the analytical models was checked by the test data. The elastic section flexural stiffness under cyclic loading decreases rapidly due to tension cracking of the concrete infill and local buckling of. Structural Steel Design to Eurocode 3 and AISC Specifications ... AISC. Save for later . This paper describes an experimental study on the shear behavior of SCS continuous deep beams. The in-plane shear loading produces principal tension and compression forces in the composite SC section. The results indicate that thermal softening cannot be neglected, so an alternative procedure for identification of the material constants in the power-law constitutive relation used in the cavity-expansion theory has been proposed. The results from the experimental and numerical investigations were used to propose design and detailing recommendations for lap-splice connections. Finally, we proposed the equation to calculate the reduction ratio from the opening for design.
