Nonlinear Analysis of Concrete Structural Components Using Co-axial Rotating Smeared Crack Model

Mohammad Amin Hariri Ardebili, S. Mahdi S. Kolbadi, Masoud Heshmati and Hasan Mirzabozorg

Abstract:
Simulation of concrete behavior in structural components and estimation of real crack profile under static and dynamic loads is one of the most interesting fields in structural engineering. In the present study, a co-axial rotating smeared crack model is proposed for mass concrete in 3D space. The advantages of this model are using variable shear transfer coefficient which is updated in each load step; utilizing an advanced failure criterion for concrete and ability of modeling concrete cracking in tension and also crushing in compression. The proposed model is verified considering concrete beams under concentrated loads and comparing the results with those available in the literature. In addition, a finite element model of prototype gravity dam-reservoir-foundation system is provided in order to investigation the nonlinear dynamic behavior of large concrete specimens considering fluid-structure-interaction. The responses of the dam as well as crack profiles are compared for constant and variable shear transfer coefficients under various types of dynamic loads. Results show great compatibility of numerical modeling and experimental tests. In addition, results confirm importance of shear transfer coefficients in dynamic analysis of concrete gravity dams.
