Based on the analysis of concrete material model, reinforcing steel material model, multi-parameter strength criterion of the ANSYS, finite element models for threedimensional nonlinear reinforced concrete structures have been constructed and a three-dimensional finite element nonlinear analysis program for reinforced concrete structures has been developed with the ANSYS software. A high strength RC beam is simulated and studied by the program. In the program, two models of reinforcing bar, separated and distributive, are considered. Many finite element models and material models provided by the ANSYS are adopted. The differences of the results obtained by using different model combination are presented and the reasons of the differences are discussed. Through comparing different combinations, the nonlinear material model that can effectively simulate the failure performance of reinforced concrete structures is presented.

“…In recent years, with the development of computer capability, nonlinear finite element analysis has been applied to large-scale complicated structures. With proper concrete constitutive models, a number of studies have demonstrated the potential and reliability of the nonlinear finite element method for analysis of concrete structures (Balakrishnan and Murray 1988;Lee and Fenves 1998;Wang and Hsu 2001;Rabczuk and Eibl 2004).…”

The integrity of ageing bridges is in doubt because of increasing traffic loads, deterioration of materials, possible damage during service, and revised code requirements. Traditional methods in prediction of load varying capacity of bridges are usually based on the design blueprints and may not reflect the bridge condition as is. In this paper, the nonlinear finite element analysis, incorporating the model updating technique, is used to predict the behaviour of a 30-year-old slab-girder bridge. The original finite element model based on the design drawings is updated by modifying the stiffness parameters of the girders, slab, shear connectors and bearings so that the vibration properties of the model match the field vibration measurement data. The updated model represents the present condition of the bridge better than the original model that is based on the design blueprints. The load carrying capacity of the bridge is then calculated using the original and updated finite element models, respectively, with consideration of nonlinear material properties. The comparison shows that the bridge load carrying capacity under the present condition is lower than that under the design condition, whereas is still above the design requirement. The influence of the shear connectors on the load carrying capacity is specially investigated.

“…In the tension-compression (T-C) range, either a cracking or a crushing event can be detected when a point on the envelope is reached. The compression strength reduction of cracked concrete must be considered; the solution for the T-C range adopted here [15], within the framework of the model by Balakrishnan and Murray [30], substantially adopts the development proposed by Ayoub and Filippou [31], though with a different analytical formulation.…”

This work focuses on the modelling issues related to the adoption of the pushover analysis for the seismic assessment of existing reinforced concrete (RC) structures. To this purpose a prototype reference structure, one of the RC shear walls designed according to the multi-fuse concept and tested on shaking table for the CAMUS project, is modelled at different levels of refinement. The meso-scale of a stiffness-based fibre element and the micro-scale of the finite element (FE) method are herein adopted; in the latter separate elements are adopted for the concrete, the steel and the steel-concrete interface. This first of the two companion papers presents in detail the wall under study, illustrating the design philosophy, the geometry of the wall, the instrumentation set-up and the test programme. The two modelling approaches are then described; the most important points in terms of element formulation and constitutive relations for materials are presented and discussed for each approach, in the light of the particular design of the wall and of its experimental behaviour. fact: the necessity to assess both the effectiveness of the new seismic design codes and the performance of many existing structures, designed according to seismic provisions that have been judged insufficient. In both cases a challenging task must be faced: experimental and numerical simulations of the structural response in the non-linear dynamic/cyclic range are often necessary, since a direct study of earthquake excited structures is seldom possible. Experimental tests, however, are quite costly and often limited to structural components; they should provide the calibration of non-linear models to be adopted in numerical analyses. Highly refined models are needed to fully reproduce the complex degradation phenomena in the non-linear range, while simple models, a compromise between accuracy and simplicity, are necessary if a whole structure must be analysed under the effect of several earthquakes.Moreover, the philosophy of seismic design itself is at the moment under review. Recent earthquakes (Northridge 1994, Hanshin-Awaji-Kobe 1995 have shown that the level of damage to structures and the consequent economic losses have been unexpectedly high, even though buildings designed according to recent codes have performed well from the point of view of the safety of human lives. This fact has given rise to some criticism on the conventional methods of seismic design, aiming to fulfil the no-collapse requirement and based on limits on stresses and member forces resulting from a prescribed set of lateral forces or a design spectrum. The presence of many uncertainties about both the seismic demand and the seismic capacity of the structure in fact makes it difficult to assess the level of performance guaranteed with a specific design for earthquakes of different intensities. A more general design philosophy, the performance-based design, has thus been proposed, 'in which the design criteria are expressed in terms of achieving stated performance object...
