Available in PDF, EPUB and Kindle. Book excerpt: In Finite Element Design of Concrete Structures: practical problems and their solutions the author addresses this blind belief in computer results by offering a useful critique that important details are overlooked due to the flood of information from the output of computer calculations. Indeed, errors in the numerical model may lead in extreme cases to structural failures as the collapse of the so-called Sleipner platform has demonstrated.

This book was released on 2008-01-01 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-linear computer analysis methods have seen remarkable advancement in the last half-century. The state-of-the-art in non-linear finite element analysis of reinforced concrete has progressed to the point where such procedures are close to being practical, every-day tools for design office engineers. Non-linear computer analysis procedures can be used to provide reliable assessments of the strength and integrity of damaged or deteriorated structures, or of structures built to previous codes, standards or practices deemed to be deficient today. They can serve as valuable tools in assessing the expected behaviour from retrofitted structures, or in investigating and rationally selecting amongst various repair alternatives. fib Bulletin 45 provides an overview of current concepts and techniques relating to computer-based finite element modelling of structural concrete. It summarises the basic knowledge required for use of nonlinear analysis methods as applied to practical design, construction and maintenance of concrete structures, and attempts to provide a diverse and balanced portrayal of the current technical knowledge, recognizing that there are often competing and conflicting viewpoints. This report does not give advice on picking one model over another but, rather, provides guidance to designers on how to use existing and future models as tools in design practice, in benchmarking of their models against established and reliable test data and in selecting an appropriate safety factor as well as recognising various pitfalls. fib Bulletin 45 is intended for practicing engineers, and therefore focuses more on practical application and less on the subtleties of constitutive modelling.

This book was released on 2012 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report, 3-D Finite Element Modeling of Reinforced Concrete Beam-Column Connections -- Development and Comparison to NCHRP 12-74, investigates the use of finite element modeling (FEM) to predict the structural response of the cast-in-place (CIP) reinforced concrete bent cap-column test specimen reported in NCHRP Report 681 -- Development of a Precast Bent Cap System for Seismic Regions. Analysis was performed using LS-DYNA as the finite element processor. The Karagozian & Case Damaged Concrete model, material MAT_072, was used as the constitutive model for all concrete elements and material MAT_003, a plastic kinematic model, was used as the constitutive model for the reinforcing steel. Strain-hardening effects of steel were neglected for this analysis. Boundary conditions on the FE model were identical to the vertical and horizontal restraints used on the CIP specimen during testing. The FE model only considered a monotonic push loading sequence, whereas the CIP specimen was subjected to reverse cyclic loading. To account for the difference in loading, the FE model results were compared to the hysteretic envelope from the CIP specimen. The lateral load-lateral displacement response of the FE model (Model 1) compared reasonably well to the actual and theoretically predicted response of the CIP specimen. For lateral displacements less than that corresponding to a displacement ductility of 4.1, the FE model showed a larger stiffness than the actual CIP response. The model stiffness degraded as a greater number of concrete elements in the column plastic hinging region accumulated damage. The degradation and lateral load-displacement response matched the predicted response within 5% for a displacement ductility larger than 2.0; however, the model degradation was not as severe as that observed for the CIP specimen. Concrete damage in the FE model correlated reasonably well with observed cracking and spalling of the CIP specimen. Significant damage was observed in the column of the FE model, near the joint, reflecting flexural cracking. Initial yielding of column longitudinal bars in the FE model occurred at a displacement ductility 26% larger than the CIP specimen. Based on contours of concrete damage and principal stress vectors, the primary shear crack formed diagonally through the joint of the FE model at a lateral load 6% higher than that of the CIP specimen. Joint rotation for the FE model was significantly less than that of the CIP specimen, approximately half of the specimen values. Conclusions include: 1) finite element modeling using appropriate constitutive models and element formulation can accurately capture the nonlinear behavior of reinforced concrete beam-column connections, including flexural cracking, joint shear cracking, steel reinforcement yielding and overall stress distribution; 2) element size for concrete and steel reinforcement significantly impacts the overall response and accuracy of results and therefore must be carefully selected for convergence; 3) the Karagozian & Case damaged concrete model, material MAT_072, can accurately capture the cracking of concrete using limited inputs (f 'c and aggregate size). Recommendations include: 1) additional analysis should be performed to appropriately incorporate a strain hardening model for the reinforcing steel; 2) strain distribution of the steel reinforcement in the joint (longitudinal reinforcement, joint hoops, and joint stirrups) should be further investigated as well as the hoop strain distribution in the column plastic hinge region; 3) a concrete constitutive model capable of reverse cyclic loading should be investigated; 4) a bar slip model for bond between the concrete and reinforcing steel should be investigated.

Book excerpt: "A finite element model which uses the advanced endochronic stress-strain relationship and incorporates the results of the investigation on post-cracking behaviour and steel-concrete interface behaviour is formulated and used in the analysis of several reinforced concrete members. Analysis results are compared with the available experimental data and with the results obtained by other researchers. Excellent correlation was obtained between the computed values and the experimental results." --

This book was released on 2016-04-04 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presents the theoretical basis of Additional Finite Element Me-thod (AFEM), which is a variant of the Finite Element Method (FEM) for analy-sis 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 prob-lem is solved by introduction of ideal failure models and additional design dia-grams formed from additional finite elements, where each AFE describes the limit state reached by the main element. The main relations defining the proper-ties of AFEs as well as the examples of the use of Additional Finite Element Me-thod for analysis of reinforced concrete structures at limit state are given in the work too.

This book was released on 2004 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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.
