Available in PDF, EPUB and Kindle. Book excerpt: Concrete beam with openings usually use to provide building services, such as conduits and pipes to pass through the beam so that the layout on water reticulation and electrical system will be more systematic. It also provide the ease of maintenance on building utility and reduces the financial during construction of high-rise building. However, beam with opening experience great losses of load capacity. In order to regain such losses, the strengthening method is investigated so that the strength of the concrete beam will be able to cover to the maximum. In this study, the behavior of the openings were investigated in terms of load-deflection, crack pattern and stress distribution. The simulation of strengthening concrete beam with openings by using CFRP laminates were conducted on RC beam with openings. There were three different types of beam that was analyzed in this study, which were solid RC beam, RC beam with openings and the strengthening RC beam with openings by using CFRP laminates. They were modelled using finite element software, ANSYS 12.0 in three degree of freedom. The location of the openings distinguished into zero distance, 140 mm and 280 mm from the supports. The beams were analyzed under four points loading. The result from numerical analysis was compared with the experimental result. The un-strengthened RC beams were found out that the beam reduced the ultimate load capacity at about 67 - 80% of the control beam. When the location of the opening was shifted further away from the support, the beam experienced less reduction of the ultimate load of the solid beam. Thus, the critical location of the opening was concluded at the face of the support. However, whenever the CFRP was installed around the opening region. The beam was able to fortify and regained at about 34 - 44% of ultimate load of the solid beam. Even though the beam was applied with CFRP laminates, they eventually failed on the shear zone. In conclusion, this research was able to prove that the beam was fortified by the CFRP strengthening method. A good agreement between numerical result and experimental result in literature was obtained based on the load-deflection relationship.

This book was released on 1994 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The linear finite element analysis of a reinforced concrete beam, using cosmos/m, a finite element analysis system is presented. The objective of this study was to find a suitable model to represent the behaviour of a simply supported reinforced concrete beam in flexure.The elements form the cosmos/m element library was utilised to model the beam, they are; (a) the three noded triangular element and (b) 8 node quadrilateral plane stress element, (c) 8 node solid element and (d) the 4 node composite quadrilateral shell element. The main area of investigations include the determination of the midspan displacement as well as the stress and strainvariation in the beam up to failure. Three different material modelling forconcrete was adopted namely : constant E-value throughout, different E-valueand varying E-value for concrete in tension. The performance of the variouseelement were compared and the predicated displacements, stress and strain form the finite element analysis were compared with experimental results of two reinforced concrete beams. Discrete crack was simulated in the finite element model using the 8 node quadrilateral plane stress element and the influence on the predicted results was examined. It can be concluded that from theF.E.A the 8 node quadrilateral plane stress element gave the closest correspondence with the test results and the third material model was found to be most suitable model.

This book was released on 2012 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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 or read book Practitioners Guide to Finite Element Modelling of Reinforced Concrete Structures written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. 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.
