Abstract
AbstractA new simplified modelling strategy to simulate the non‐linear behaviour of reinforced concrete shear walls under dynamic loading is presented. The equivalent reinforced concrete (ERC) model is derived from the framework method and uses lattice meshes for concrete and reinforcement bars and uniaxial constitutive laws based on continuum damage mechanics and plasticity. Results show the capacity of the model to analyse structures having different slenderness and boundary conditions. For low reinforcement ratios however, results are sensitive to the angle formed by the diagonals of the concrete lattice and the horizontal bars. The method is compared with the shear multi‐layered beam model that uses Timoshenko multi‐layered 2D beam elements and biaxial constitutive laws. Comparisons for both models with experimental results of two research programs (one organized by NUPEC and the other by COGEMA and EDF) are provided. ERC is a simplified method that intends to save computer time and allows parametrical studies. Copyright © 2002 John Wiley & Sons, Ltd.
Highlights
The simulation of the non-linear behaviour of load bearing walls made of reinforced concrete under dynamic loading is an important problem for the engineering community
The purpose of this paper is to propose an original and simpliÿed modelling strategy to reproduce the non-linear behaviour of shear walls under dynamic loading
We have demonstrated the ability of the equivalent reinforced concrete (ERC) model to successfully simulate the non-linear behaviour of shear walls having a small slenderness when the rotation of the top is allowed, a case where our shear multilayered beam model (SMB) model applies as well
Summary
The simulation of the non-linear behaviour of load bearing walls made of reinforced concrete under dynamic loading is an important problem for the engineering community. Recent earthquakes in Kobe (Japan), Izmit (Turkey) and Athens (Greece) have shown the key role that such structural elements play for the safety of buildings. Since they act as major earthquake resisting members, their dynamic characteristics dominate the response of the structure. The Laboratoire de MeÃcanique et Technologie (LMT) has already proposed a simpliÿed modelling strategy for bearing walls dominated by exure. The elastic properties of the bars (sections) for the two patterns are given by Pattern 1
