Long-term Stress of Simply Supported Steel-concrete Composite Beams
The theoretical model to compute the long-term stress of simply supported steel-concrete composite beam was deduced. The model includes the effects of steel bars in concrete slab, concrete shrinkage and creep. The computed results agreed well with the test results. On this basis, the effects of factors such as concrete age to loading, longitudinal reinforcement ratio in concrete slab, concrete ...
متن کاملAn Investigation on the Nonlinear Free Vibration Analysis of Beams with Simply Supported Boundary Conditions Using Four Engineering Theories
The objective of this study is to present a brief survey on the geometrically nonlinear free vibrations of the Bernoulli-Euler, the Rayleigh, shear, and the Timoshenko beams with simple end conditions using the Homotopy Analysis Method HAM . Expressions for the natural frequencies, the transverse deflection, postbuckling load-deflection relation to, and critical buckling load are presented. The...
متن کاملRehabilitation of Rectangular Simply Supported RC Beams with Shear Deficiencies Using CFRP Composites
The present study examines the shear performance and modes of failure of rectangular simply supported reinforced concrete (RC) beams designed with shear deficiencies. These members were strengthened with externally bonded carbon fiber reinforced polymer (CFRP) sheets and evaluated in the laboratory. The experimental program consisted of twelve full-scale RC beams tested to fail in shear. The va...

متن کاملFree Vibration of Simply Supported Rectangular Composite Plates with Patch Mass
The effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. The third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. Equations of motion of the plate are obtained with the help of calculus of variation. Parametric study ...
