Calculation of Different Stages Reinforced Concrete Beam Bending Stiffness

Abstract:

By means of inertia-moment method, formulae are derived for calculating flexural rigidity of RC beams under different loading stage, which can be used for calculating initial rigidity and rigidity in service stage. Involving less parameters, it’s convenient to use the formulae. As for four examples, calculations are carried out by both code method and formulations given in this paper, and satisfied results are shown. Further more, based on finite rib method, nonlinear-all-rang analysis is done for M-B of beam sections.
