Abstract: A method is proposed for the analysis of the nonlinear behavior up to failure of reinforced-concrete membrane elements. The approach considers a linear elastic behavior for concrete before cracking; after cracking, the ...

Abstract: Under tensile stress, concrete fails at low average strain but a high local strain due to nonuniform strain distribution. It is demonstrated that the use of optical interferometry with laser light both provides adequate ...

Abstract: In reinforced concrete beams, the sectional definition of the moment-curvature relationship is not straightforward owing to the presence of cracks. In general, this problem has been solved by considering a representative ...

Abstract: According to many code requirements for concrete structures, the stress in the compressed part of reinforced concrete (RC) beams in bending is usually computed by means of uniaxial stress-strain relationships. These ...
