Serviceability Limit State of Concrete Structures by FIB – International Federation for Structural Concrete Pdf

Serviceability limit states are essential for appropriate function and durability of concrete structures. The attention is paid especially to the stress limitation, crack width analysis and deflection analysis. The document provides supplementary information to the fib Model Code 2010 (MC2010), where a limited space did not allow for a detailed description of individual procedures. The principles used in MC2010 in chapter 7.6 are explained in detail within this document. The stress analysis is focused on stresses in concrete and steel including the stress redistribution due to the long-term load and cracking of reinforced concrete and prestressed concrete elements. Crack width analysis explains the mechanism of cracking under mechanical loading and due to deformation restraint. Cracks in prestressed concrete elements are also discussed. Deflection analyses with different levels of accuracy are described including the shear effects. Examples illustrate the practical application of rules defined in the MC2010 of individual serviceability limit states. Simplified and more general methods are used. An important part of the bulletin shows the development and extension of the serviceability limit states after publishing of the MC2010 and alternative approaches. Special attention is paid to deflections of prestressed concrete beams, shear effects on deflection, slenderness limits and influence of the concrete cover. The final part deals with an application of numerical simulations.

Time-Dependent Behaviour of Concrete Structures by Raymond Ian Gilbert,Gianluca Ranzi Pdf

Serviceability failures of concrete structures involving excessive cracking or deflection are relatively common, even in structures that comply with code requirements. This is often as a result of a failure to adequately account for the time-dependent deformations of concrete in the design of the structure. The serviceability provisions embodied in codes of practice are relatively crude and, in some situations, unreliable and do not adequately model the in-service behaviour of structures. In particular, they fail to adequately account for the effects of creep and shrinkage of the concrete. Design for serviceability is complicated by the non-linear and inelastic behaviour of concrete at service loads. Providing detailed information, this book helps engineers to rationally predict the time-varying deformation of concrete structures under typical in-service conditions. It gives analytical methods to help anticipate time-dependent cracking, the gradual change in tension stiffening with time, creep induced deformations and the load independent strains caused by shrinkage and temperature changes. The calculation procedures are illustrated with many worked examples. A vital guide for practising engineers and advanced students of structural engineering on the design of concrete structures for serviceability and provides a penetrating insight into the time-dependent behaviour of reinforced and prestressed concrete structures.

Ultimate Limit-state Design of Concrete Structures by M. D. Kotsovos,M. Pavlovic Pdf

Structural concrete members often show great deviation in structural performance from that predicted by the current code of practice. In certain cases the predications considerably underestimate the capabilities of a structure or member, while in others the predictions are unsafe as they overestimate the member's ability to perform in a prescribed manner. Clearly, a rational and unified design methodology is still lacking for structural concrete. This book presents a simplified methodology based on calculations which are quick, easily programmable and no more complex than those required by the current codes. It involves identifying the regions of a structural member or structure through which the external load is transmitted from its point of application to the supports and then strengthening these regions as required. As most of these regions enclose the trajectories of internal compression actions the technique has been called the 'compressive force path' method. Ultimate limit-state design for concrete structures will provide designers with a practical and easily applied method for the design of a concrete structure, which is fully compatible with the behaviour of concrete (as described by valid experimental evidence) at both the material and structural level.

Limit State Design of Concrete Structures by Ramchandra,V. Gehlot Pdf

Bureau of Indian Standards, Delhi made large number of changes and alterations in IS: 456-2000, Code of Practice for Plain and Reinforced concrete. Realizing the necessity and importance, authors have updated the complete text and presented this subject "Limit State Design of Concrete Structures". Ultimate Limit State (ULS- conditions to be avoided) and serviceability Limit State (SLS- limits undesirable cracks and deflections) are two main essential elements of this subject. ULS includes `Limit State of Collapse in compression, in flexure, in shear and in torsion as sub elements. Whereas, SLS includes Limit State of Serviceability for deflections, cracking, fatigue, durability and vibrations as sub-elements. Features: (i) Text for life of concrete structures, fire resistance and corrosion. (ii) For all those, who carry-out their design using computer-programme, authors have given procedures (developed by them) for determining the stress in Hysd-steel bars corresponding to strain developed in concrete.

Reinforced Concrete Beams, Columns and Frames by Jostein Hellesland,Noël Challamel,Charles Casandjian,Christophe Lanos Pdf

This book is focused on the theoretical and practical design of reinforced concrete beams, columns and frame structures. It is based on an analytical approach of designing normal reinforced concrete structural elements that are compatible with most international design rules, including for instance the European design rules – Eurocode 2 – for reinforced concrete structures. The book tries to distinguish between what belongs to the structural design philosophy of such structural elements (related to strength of materials arguments) and what belongs to the design rule aspects associated with specific characteristic data (for the material or loading parameters). A previous book, entitled Reinforced Concrete Beams, Columns and Frames – Mechanics and Design, deals with the fundamental aspects of the mechanics and design of reinforced concrete in general, both related to the Serviceability Limit State (SLS) and the Ultimate Limit State (ULS), whereas the current book deals with more advanced ULS aspects, along with instability and second-order analysis aspects. Some recent research results including the use of non-local mechanics are also presented. This book is aimed at Masters-level students, engineers, researchers and teachers in the field of reinforced concrete design. Most of the books in this area are very practical or code-oriented, whereas this book is more theoretically based, using rigorous mathematics and mechanics tools. Contents 1. Advanced Design at Ultimate Limit State (ULS). 2. Slender Compression Members – Mechanics and Design. 3. Approximate Analysis Methods. Appendix 1. Cardano’s Method. Appendix 2. Steel Reinforcement Table. About the Authors Jostein Hellesland has been Professor of Structural Mechanics at the University of Oslo, Norway since January 1988. His contribution to the field of stability has been recognized and magnified by many high-quality papers in famous international journals such as Engineering Structures, Thin-Walled Structures, Journal of Constructional Steel Research and Journal of Structural Engineering. Noël Challamel is Professor in Civil Engineering at UBS, University of South Brittany in France and chairman of the EMI-ASCE Stability committee. His contributions mainly concern the dynamics, stability and inelastic behavior of structural components, with special emphasis on Continuum Damage Mechanics (more than 70 publications in International peer-reviewed journals). Charles Casandjian was formerly Associate Professor at INSA (French National Institute of Applied Sciences), Rennes, France and the chairman of the course on reinforced concrete design. He has published work on the mechanics of concrete and is also involved in creating a web experience for teaching reinforced concrete design – BA-CORTEX. Christophe Lanos is Professor in Civil Engineering at the University of Rennes 1 in France. He has mainly published work on the mechanics of concrete, as well as other related subjects.

Limit State Design of Steel Structures by Ramchandra,V. Gehlot Pdf

Method of Limit State (Ultimate Limit State, (ULS) and serviceability limit state (SLS)) present an improved design philosophy and makes allow-ance for the short-compings of working stress method (conventional and long time used in practice). This method provides basic framework, within which the performance of the steel structures may be assessed against various limiting conditions and invo-lves some concept of probability. Object of limit design method is to get steel structure that will remain fit for use during its life with acceptable target reliability. The probability of a limit state being reached during its life time is kept very small. This method has been broadly adopted in many developed countries and based on the recommendations of IS: 800-2007 (Third Revised Edition). This method has been covered in nine parts (in twenty six chapters and four appendices) as listed in contents. After introducing `Limit State Method of Design of Concrete Structures (LSD: CC) in IS: 456-1978, it was natural for Bureau of Indian Standard to introduce `Limit State Design of Steel Structures (LSD: SS). SI units for text for complete book, uncertainties involved in the working stress method and the concept of partial safety factors for the loads and strength of mate-rials (for yield and ultimate stresses reached) are the special feature of the book. Concepts of shear centre for thin-walled beam cross-sections and unsymmetrical bending of beams are important for various requirements and have been included in appendices. The text of book has been covered in about 1000 pages and 550 diagrams. The texts of various topics has been explained in many illustrative worked-out examples.
