| Abstract |
There is much research relating to shear strength of reinforced concrete beams and composite beams. However, some current shear design provisions and formulations are still too complex to be easily understood by engineers, with a different equation for each particular situation. With the aim of solving these problems, the current paper presents the extension of shear design procedure to composite beams. For composite beams with web reinforcement and without the one, the shear design procedure is based on the provisions and formulations, taking into account the result of an cumulative shear strength method that is previously developed. For strength evaluation, structural parameters such as compressive strength, H-steel size effects, tensile steel ratio, and shear span depth ratio are involved. showed tendency of overestimation according to increase of steel ratio and H-steel size effects in the BS8110 provision. On the other hand, is superior in conformability with an experiment result JSCE provision among other equations. The proposal equation know that expect rationally about shearing strength. Therefore, equation is considered to be utilized usefully evaluating shear strength by change of the shear span depth ratio of composite beam, tensile steel ratio, H-steel size effects and compressive strength of the concrete in this research. |
