DOWNLOAD EBOOKExperimental programs in laboratories give real results to identify nonlinear behavior of reinforced concrete (RC) structures but they are limited to knowledge of particular cases under restricted structural dimensions, sizes, shapes, loading and boundary conditions but the computational simulation approach has no limit to its application. Constitutive models are developed to simulate the dynamic nonlinear response of concrete and steel reinforcement subjected to cyclic loading varying randomly in magnitude. The behavior of structural concrete under monotonic loading is affected by important material aspects including cracking, crushing, tension stiffening, compression softening and bond slip. Reversed cyclic loading introduces further complexities such as stiffness degradation in concrete and the Bauschinger effect in reinforcing steel. In this research the validity and reliability of some proposed constitutive models for concrete considering general loading i.e. cyclic, monotonic, partial, common point and transition loading are evaluated. Amongst many existing constitutive models, because of their simplicity and common usage in the finite element analysis of RC structures, only some common proposed models based on nonlinear elasticity-based approach are investigated. These models are verified against experimental data available in the literature and the results are discussed. In this study, also, a hysteretic stressstrain model is developed for unconfined concrete with the intention of providing efficient modeling for the structural behavior of concrete in seismic regions. The proposed model is based on the findings of previous experimental and analytical studies. The model for concrete subjected to monotonic and cyclic loading, comprises four components in compression and tension; an envelope curve (for monotonic and cyclic loading), an unloading curve, a reloading curve, and transition curve. Also presented are formulations for partial unloading and partial reloading curves. The proposed Constitutive model reliability is investigated by RC members non-linear finite element analysis (FEM) using by finite element software ABAQUS. Comparisons with test results showed that the proposed model provides a good fit to a wide range of experimentally established hysteresis loops.

DOWNLOAD EBOOKThe results obtained from four numerical tests indicate that the proposed computational scheme and the implemented codes are accurate and reliable. The need to incorporate fire loads into reinforced concrete structural design has long been recognized, and the traditional design method for structural fire resistance has been widely practiced by engineers mainly because of its simplicity. To simulate the structure's response to thermal loads, this research develops and implements a 2D nonlinear finite element transient analysis for reinforced concrete structures subjected to high temperatures. The proposed computational scheme takes into account time-varying thermal loads, heat-of-hydration effects, and temperature-dependent material properties. Algorithms for calculating the closed-form element stiffness for a quadrilateral element with a fully-populated material stiffness are also developed. Then, the capability of a 2D nonlinear finite element transient thermal analysis is implemented into program VecTor2(c), a nonlinear analysis program for 2D reinforced concrete membranes.

DOWNLOAD EBOOKThe work presents the theoretical basis of Additional Finite Element Method (AFEM), which is a variant of the Finite Element Method (FEM) for analysis of reinforced concrete structures at limit state. AFEM adds to the traditional sequence of problem by FEM the units of the two well-known methods of the structural design: method of additional loads and limit state method. The problem is solved by introduction of ideal failure models and additional design diagrams formed from additional finite elements, where each AFE describes the limit state reached by the main element. The main relations defining the properties of AFEs as well as the examples of the use of Additional Finite Element Method for analysis of reinforced concrete structures at limit state are given in the work too.

DOWNLOAD EBOOKThe stress transfer behavior between reinforcing steel and surrounding concrete through bond and slip plays an important role in the response of reinforced concrete structures, especially in their hysteretic response. This thesis studies the bond-slip relationship under both monotonic loading and cyclic loading. Two types of bond elements, contact elements and linkage elements, are developed and bond stiffness matrices are derived. Four bond-slip models are presented based on the findings of previous experimental studies. The degradation of bond resistance is included in the bond-slip models. The two bond elements and four bond-slip models are added into the nonlinear finite element program TRIX99. The finite element models are then used to study the behavior of reinforced concrete walls subjected to cyclic lateral load. The accuracy of the models are assessed by comparison of the finite element numerical response with experimental data from four reinforced concrete shear walls tested under cyclic loading. The NLFEA program with the nonlinear material models for concrete, reinforcing bar and bond-slip is capable of reproducing the important features of the measured hysteretic response of reinforced concrete walls with a variety of cyclic loading histories and configurations of walls. The program is able to successfully predict the load-deflection values of the reinforced concrete structures under cyclic loading. The proposed finite element method provides an efficient method for evaluating the monotonic and cyclic response of the reinforced concrete structures.
