Download or read book Treatment of Imperfections in Precast Structural Elements written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2007-01-01 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 41 addresses the most common types of imperfections encountered during the manufacture, stacking, transport and erection of precast concrete structural elements, and suggests a number of possible remedial actions. The remedial actions depend on the severity of the imperfection, the feasibility of repair and the consequences on the intended use of the concrete member. Imperfections in concrete structures are impossible to avoid and can range from minor surface blemishes to major structural defects. Because many imperfections are at the limits of specified quality deviations, or are not included in the acceptance criteria, the problem is more complex than a decision between rejection or acceptance. This document deals with precast concrete elements that do not meet the quality as intended in the design. It compares imperfections in quality to the specified requirements so that the effect of the imperfection can be evaluated. Recommendations are provided on methods to prevent such imperfections, the effect they can have and any necessary actions for rectification. The bulletin applies to prefabricated concrete members made of reinforced or prestressed normal weight concrete. Products include beams and columns, concrete walls, hollow core slabs, double tees, planks and beams for beam and block floors. Water retaining structures are outside the scope of this document.

Available in PDF, EPUB and Kindle. Book excerpt: "El presente libro es un modesto aporte en la comprensión de los fenómenos patológicos que agreden al hormigón armado y a las estructuras que con este material se construyen. Los primeros capítulos permiten introducir al lector en los conceptos generales del hormigón armado como material y sus características. En los siguientes capítulos se efectúa un análisis de los procesos físicos, mecánicos, químicos y biológicos que afectan la durabilidad del hormigón armado. La profundidad del desarrollo de los procesos procura ahondar en aquellos que no siempre son tratados con detalle y no en los que se poseen amplio desarrollo en la bibliografía disponible. Existe un apartado especial para las estructuras con requerimientos de estanqueidad, en el que se detallan algunas medidas para incrementar el control de la fisuración y su durabilidad. Al respecto, la fisuración, el control de las deformaciones y la acción del fuego tienen un tratamiento particular en los Capítulos 8, 9, 10 y 11. En el Capítulo 12 se mencionan algunos de los principales procesos patológicos ocurridos en las fundaciones. En el Capítulo 15, se hace hincapié en las medidas de protección, refuerzo y reparación, al desarrollar conceptos como el recrecido de vigas y columnas, refuerzos con perfiles de acero o materiales como el CFRP. En el Capítulo 16 se incluye un apartado referido al uso de micropilotes inyectados para el recalce de fundaciones. Finalmente, en el Anexo I se desarrollan conceptos básicos sobre la elaboración y uso de hormigón autocompactante que tiene un ámbito de aplicación importante, entre otros, en el recrecido y refuerzo de las estructuras de hormigón armado. Se ha procurado amenizar la lectura del texto y plasmar los conceptos con soluciones numéricas, superando las 350 figuras y los 36 ejemplos de aplicación. No obstante, y a pesar de hacer mención a procesos patológicos, el texto procura ser precautorio, es decir, desarrolla contenidos para prevenir la ocurrencia de fallas y mecanismos que puedan agredir al hormigón."

Download or read book FRP Reinforcement in RC Structures written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2007-01-01 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 40 deals mainly with the use of FRP bars as internal reinforcement for concrete structures. The background of the main physical and mechanical properties of FRP reinforcing bars is presented, with special emphasis on durability aspects. For each of the typical ultimate and serviceability limit states, the basic mechanical model is given, followed by different design models according to existing codes or design guidelines. Composite FRP materials are still relatively new in construction and most engineers are unfamiliar with their properties and characteristics. The second chapter of this bulletin therefore aims to provide practising engineers with the necessary background knowledge in this field, and also presents typical products currently available in the international market. The third chapter deals with the issue of durability and identifies the parameters that can lead to deterioration, which is necessary information when addressing design issues. A series of parameters is used to identify the allowable stress in the FRP after exposure for a specified period of time in a specific environment. The bulletin covers the issues of Ultimate Limit States (primarily dealing with flexural design), Serviceability Limit States (dealing with deflections and cracking), Shear and Punching Shear and Bond and Tension Stiffening. It provides not only the state-of-the-art but also in many cases ideas for the next generation of design guidelines. The final chapter deals with the fundamental issue of design philosophy. The use of these new materials as concrete reinforcement has forced researchers to re-think many of the fundamental principles used until now in RC design. The bulletin ends with a discussion of a possible new framework for developing partial safety factors to ensure specific safety levels that will be flexible enough to cope with new materials.

Download or read book Retrofitting of Concrete Structures by Externally Bonded FRPs With Emphasis on Seismic Applications written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2006-01-01 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 35 is the first bulletin to publish documentation from an fib short course. These courses are held worldwide and cover advanced knowledge of structural concrete in general, or specific topics. They are organized by fib and given by internationally recognized experts in fib, often supplemented with local experts active in fib. They are based on the knowledge and expertise from fib's ten Commissions and nearly fifty Task Groups. fib Bulletin 35 presents the course materials developed for the short course "Retrofitting of Concrete Structures through Externally Bonded FRP, with emphasis on Seismic Applications", given in Ankara and Istanbul in June 2005. The course drew on expertise both from outside Turkey and from the large pool of local experts on this subject. In most countries of the world, the building stock is ageing and needs continuous maintenance or repair. Moreover, the majority of existing constructions are deficient in the light of current knowledge and design codes. The problem of structural deficiency of existing constructions is especially acute in seismic regions, as, even there, seismic design of structures is relatively recent. The direct and indirect costs of demolition and reconstruction of structurally deficient constructions are often prohibitive; furthermore they entail a substantial waste of natural resources and energy. Therefore, structural retrofitting is becoming increasingly widespread throughout the world. Externally bonded Fibre Reinforced Polymers (FRPs) are rapidly becoming the technique of choice for structural retrofitting. They are cleaner and easier to apply than conventional retrofitting techniques, reduce disruption to the occupancy and operation of the facility, do not generate debris or waste, and reduce health and accident hazards at the construction site as well as noise and air pollution in the surroundings. fib Bulletin 35 gives state-of-the-art coverage of retrofitting through FRPs and presents relevant provisions from three recent standardisation milestones: EN 1998-3:2005 "Eurocode 8: Design of structures for earthquake resistance - Part 3: Assessment and retrofitting of buildings", the 2005 Draft of the Turkish seismic design code, and the Italian regulatory document CNR-DT 200/04, "Instructions for Design, Execution and Control of Strengthening Interventions by Means of Fibre-Reinforced Composites" (2004).

Download or read book World Expos written by Isaac López César and published by Architect Publications. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a fascinating journey along the history of architectural structures over the last 150 years, taking the World Expos as an original unifying thread. Nevertheless, it does not solely focus on the exhibition buildings; on the contrary, these are continuously being related to buildings beyond the scope of the Expos, thus ultimately providing a general vision of the history of modern structures. This essay is destined to become an essential work of reference within the history of architectural structures. It is generously illustrated with more than nine hundred large-scale illustrations, many of which have not appeared in contemporary publications. It offers innumerable facts that will interest architects, engineers or art historians. Likewise, members of the general public far-removed from these fields will also be able to enjoy many of the passages which are accessible to those who do not have any specific knowledge of architecture or engineering.

Download or read book Seismic Assessment and Retrofit of Reinforced Concrete Buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2003-08-01 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most parts of the developed world, the building stock and the civil infrastructure are ageing and in constant need of maintenance, repair and upgrading. Moreover, in the light of our current knowledge and of modern codes, the majority of buildings stock and other types of structures in many parts of the world are substandard and deficient. This is especially so in earthquake-prone regions, as, even there, seismic design of structures is relatively recent. In those regions the major part of the seismic threat to human life and property comes from old buildings. Due to the infrastructure's increasing decay, frequently combined with the need for structural upgrading to meet more stringent design requirements (especially against seismic loads), structural retrofitting is becoming more and more important and receives today considerable emphasis throughout the world. In response to this need, a major part of the fib Model Code 2005, currently under development, is being devoted to structural conservation and maintenance. More importantly, in recognition of the importance of the seismic threat arising from existing substandard buildings, the first standards for structural upgrading to be promoted by the international engineering community and by regulatory authorities alike are for seismic rehabilitation of buildings. This is the case, for example, of Part 3: Strengthening and Repair of Buildings of Eurocode 8 (i. e. of the draft European Standard for earthquake-resistant design), and which is the only one among the current (2003) set of 58 Eurocodes attempting to address the problem of structural upgrading. It is also the case of the recent (2001) ASCE draft standard on Seismic evaluation of existing buildings and of the 1996 Law for promotion of seismic strengthening of existing reinforced concrete structures in Japan. As noted in Chapter 1 of this Bulletin, fib - as CEB and FIP did before - has placed considerable emphasis on assessment and rehabilitation of existing structures. The present Bulletin is a culmination of this effort in the special but very important field of seismic assessment and rehabilitation. It has been elaborated over a period of 4 years by Task Group 7.1 Assessment and retrofit of existing structures of fib Commission 7 Seismic design, a truly international team of experts, representing the expertise and experience of all the important seismic regions of the world. In the course of its work the team had six plenary two-day meetings: in January 1999 in Pavia, Italy; in August 1999 in Raleigh, North Carolina; in February 2000 in Queenstown, New Zealand; in July 2000 in Patras, Greece; in March 2001 in Lausanne, Switzerland; and in August 2001 in Seattle, Washington. In October 2002 the final draft of the Bulletin was presented to public during the 1st fib Congress in Osaka. It was also there that it was approved by fib Commission 7 Seismic Design. The contents is structured into main chapters as follows: 1 Introduction - 2 Performance objectives and system considerations - 3 Review of seismic assessment procedures - 4 Strength and deformation capacity of non-seismically detailed components - 5 Seismic retrofitting techniques - 6 Probabilistic concepts and methods - 7 Case studies
