“…RC panels, for instance, have to be modelled as multi-component structural systems: concrete, reinforcing bars and interaction between these two phases. This is the way used by many authors, namely Lee (2011), Marti et al (1998), Okamura and Kim (2000), Pimentel et al (2010), Selby and Vecchio (1997), Soltani et al (2005), Spacone and El-Tawil (2004) and Vecchio and Collins (1986). The main hypothesis of this first family of local refined analysis constitutive models consists in the superposition of stress distribution stemming from each phase and the interface stress; see for instance Feenstra and De Borst (1995); -for ''globalised'' RC models, the preferred approach consists in developing the constitutive model from an a priori general framework in order to formulate, in a consistent way, the state equations and the evolution laws and to define the intrinsic mechanical dissipation.…”

International audienceA new stress resultant constitutive model for reinforced concrete plates under cyclic solicitations ispresented. This model is built by the periodic homogenisation approach using the averaging methodand couples damage of concrete and periodic debonding between concrete and steel rebar. Inone-dimensional situations, we derive a closed-form solution of the local problem useful to verify andset up the plate problem. The one dimensional macroscopic constitutive model involves a limited numberof parameters, the sensibility of which is studied. Comparison to experimental results underlines the pertinenceof the model by considering internal debonding in order to properly represent the mechanicaldissipation occurring during cyclic loadings on reinforced concrete panels

“…In addition, the perfect bond and the displacement compatibility between concrete and steel material allow treating the steel as an integral part of the 3D finite element. The steel stiffness matrix is added to that of the concrete, and thus the total stiffness can be obtained as Equation 1:…”

“…Nuclear containments are unique structures that are constantly exposed to harsh environmental conditions, including high temperature, high pressure, and nuclear radiation [1]. Under these conditions, the configurations of prestressed tendons and reinforced steel in the containment are complex, and the concrete damaged property and the ultimate capacity are generally difficult to evaluate [2e4].…”

a b s t r a c tIn order to analyze the mechanical properties of two-way different configurations of prestressed concrete members subjected to axial loading, a finite element model based on the nuclear power plant containments is demonstrated. This model takes into account the influences of different principal stress directions, the uniaxial or biaxial loading, and biaxial loading ratio. The displacement-controlled load is applied to obtain the stress estrain response. The simulated results indicate that the differences of principal stress axes have great effects on the stressestrain response under uniaxial loading. When the specimens are subjected to biaxial loading, the change trend of stress with the increase of loading ratio is obviously different along different layout directions. In addition, correlation experiments and finite element analyses were conducted to verify the validity and reliability of the analysis in this study.

“…Since the 1970's, many researchers have proposed an analytical model to predict the behavior of RC shell structures using the finite element method. The main approach used by most researchers is to develop a reinforced concrete shell element by combining a rational constitutive model of reinforced concrete material into finite element formulations of a general shell element with layer approaches (Hand, Pecknold [2]; Cervera, Hinton [3]; Scordelis and Chan [4]; Hu and Schnobrich [5]; Polak and Vecchio [6]; Kim, Lee [7]; Zhang, Bradford [8]; Lee [9]; Xiang, Mo [10]; Gopinath, Iyer [11], Matešan, Radnić [12], Hrynyk and Vecchio [13], and Lu, Xie [14]). The main problem faced by most researchers in the analysis of RC shell structures using the finite element method was that it often required expensive computational time due to the complicated material models and the difficulties encountered in the stability and accuracy of the solutions.…”

Reinforced concrete shell structures have been widely used in a variety of modern engineering applications. It is found from earthquake reconnaissance that reinforced concrete (RC) shell structures, such as nuclear containments, cooling towers, roof domes, shear walls, etc., are the key elements in resisting earthquake disturbances. This paper presents the development of a finite element analysis (FEA) program, SCS-3D, to predict the inelastic behavior of RC shell structures. In the program, a Cyclic Softened Membrane Model (CSMM)-based shell element is developed based on the degenerated shell theory with a layered approach and taking into account the CSMM developed at the University of Houston. To form the FEA program, the constitutive relation modules and the analysis procedure were implemented into a finite element program development framework, OpenSees developed at UC Berkeley. Several large-scale structural tests were employed to validate the developed FEA program, including RC panels subjected to a combination of shear and bending, three-dimensional RC shear wall and cylindrical RC tanks subjected to reversed cyclic loading.
