This paper presents a review of the different models for concrete based on continuum damage theory, formulated at Laboratoire de Mécanique et Technologie (Cachan, France). Derived in framework thermodynamics irreversible processes, each formulation is physical observation. Induced anisotropy, ductile behavior, and directional effects such as closure cracks are discussed adequate proposed. Finally, numerical implementations performed give good description failure process well an accurate...
Abstract Among the “theories” applied to model concrete behavior, damage mechanics has proven be efficient. One of first models for introduced into such a framework is Mazars’ model. A new formulation this model, called “ μ model” and based on coupling elasticity within an isotropic formulation, proposed herein purpose 3D cyclic dynamic loadings. Unilateral behavior (i.e., crack opening closure) by use two internal variables. threshold surface then associated with each these The shape...

Performance-based design of structures is becoming the preferred seismic method. Its use requires special numerical programs capable predicting performance during a event well into nonlinear range. Seismic analysis results obtained from these depend on types elements and constitutive material laws used. For one type element used, can be sensitive to size elements. This paper presents simplified finite-element program based multilayer damage mechanics modeling concrete behavior. A method...
In countries with a moderate seismic hazard, the classical methods developed for strong motion prone to estimate behaviour and subsequent vulnerability of existing buildings are often inadequate not financially realistic. The main goals this paper show how modal analysis can contribute understanding building response good relevancy model based on ambient vibrations estimating structural deformation under earthquakes. We describe application an enhanced technique (Frequency Domain...
This paper is concerned with the development of a damage model for concrete materials exhibiting residual hysteretic behaviour at fixed level damage. feature obtained by coupling mechanics and friction phenomena. In its complete form, variable means which stiffness decrease in an orthotropic second-order tensor. Its evolution governed tensile part strain The sliding between crack lips assumed to have plasticity-like non-linear kinematic hardening. stress depends on Such assumes two yield...
Abstract This paper presents a non‐linear interface element to compute soil–structure interaction (SSI) based on the macro‐element concept. The particularity of this approach lies in fact that foundation is supposed be infinitely rigid and its movement entirely described by system global variables (forces displacements) defined foundation's centre. behaviour soil reproduced using classical theory plasticity.

ABSTRACT This paper presents the main results obtained during a long and intensive research period on modelling of physical mechanisms related to damage fracture concrete. The starting point has been Mazars one scalar model (Mazars, 1984, 1986). On this base Pontiroli & Rouquand have proposed in 1995 two (PRM model) which takes into account crack closure mechanism, irreversible strains, strain rate effects internal friction stresses. recently completed order take pore collapse phenomena,...
A continuous damage model and different simplified numerical strategies are proposed to simulate the behaviour of reinforced concrete (R/C) walls subjected earthquake ground motions. For 2D modelling R/C controlled primarily by bending, an Euler multilayered beam element is adopted. 3D problems, a multifibre Timoshenko having higher order interpolation functions has been developed. Finally, for with small slenderness ratio we use Equivalent Reinforced Concrete model. each case, comparison...
