せん断ひび割れを有するRCはりの数値モデル

抄録

A numerical simulation model is presented for the analysis of a reinforced concrete beam under monotonic loading based on the finite element method. The present method has an advantage of taking into account the influence of diagonal cracks in addition to flexural cracks in concrete. After having a diagonal crack. the interval corresponding to the diagonal crack with the shear deformation mode is modeled by shear type elements. The stress transfer to the shear reinforcement from the concrete is expressed by this method. The applicability of the present model to a beam with shear reinforcement is discussed. The analytical result with the present model is compared with the test data as well as the design code.
