Available in PDF, EPUB and Kindle. Book excerpt: "Fire is a rare but extreme event that subjects a structure to a unique set of demands. The fire resistance of the structure depends on its ability to resist the combination of the structural gravity loads and the effects of fire without undergoing failure during both heating and cooling. While many studies have been conducted internationally on steel-framed building components in fire, a limited number have focused on composite beams designed according to U.S. codes and standards. This project focused on the thermal and structural behavior of composite beams used in steel building floor systems through both experimental and numerical investigations. These floor systems typically consist of steel beams with a concrete deck cast on top of the beams, where composite action is developed through the use of steel headed shear studs welded to the top flange of the beam. The experimental approach included the use of high-temperature ceramic radiant heaters, vertical loading, and innovative high-temperature instrumentation techniques, including close-range photogrammetry. Isolated concrete slabs representing the concrete portion of the composite floor system were subjected to one-sided heating without the application of load to evaluate the response to a thermal gradient. Large-scale partial composite beams with simple shear beam-to-column connections were then subjected to the combination of heating and loading. There was a reduction in the composite beam load carrying capacity as a result of heating, both at elevated temperatures as well as post-fire ambient conditions. The composite beam was able to sustain service level loads with heating to steel temperatures up to 700°C. Concrete compression failure was an observed failure mode for composite beams with flat slabs at moderate steel temperatures (350-500°C) and overloading. Two modeling techniques were developed and benchmarked using experimental test data: (i) a sequentially-coupled thermal-structural 3D finite element model for evaluating both the thermal and structural response of composite beams and (ii) a 2D fiber-based model for determining the moment-curvature-temperature relationship for a composite beam cross-section. Both approaches account for temperature-dependent material properties and the force-slip behavior of the shear studs. An extensive parametric study was conducted to evaluate the effects of various parameters on the flexural capacity of composite beams at elevated temperatures. Variations in cross-section geometry, concrete deck type and orientation, percentage composite action, and thermal gradient were considered. Current U.S. design provisions for steel-concrete composite beams rely upon a strength-based approach as outlined by the American Institute of Steel Construction (AISC). In partial composite beams, the headed studs transferring interfacial shear between the concrete and steel can undergo significant slip, which is not accounted for directly in design. Results from the parametric study revealed a complex inter-relationship between the beam length, stud slip capacity, and the minimum level of partial composite action that may be permitted for design. A temperature-dependent retention factor was developed for use with the AISC method to predict the flexural capacity at elevated temperatures. Because this retention factor is a function of only the bottom flange temperature, it provides a simple design method to determine the elevated temperature capacity of a composite beam, without having to conduct an extensive thermal and structural analysis." -- Abstract.

This book was released on 2008-01-01 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is well known to behave efficiently in fire conditions, as it is incombustible, does not emit smoke, and provides good thermal insulation. Furthermore, in reinforced concrete structures, the concrete cover gives a natural protection to the reinforcement, and the size of the sections often delays the heating of the core, thus favouring the fire resistance of the structural members. In addition, concrete structures are often robust and therefore able to accommodate local damage without major consequences to the overall structural integrity. However, past experience with real fires shows that a thorough understanding of concrete behaviour and structural mechanics is still needed to improve the design of R/C structures with respect to fire. The objective of fib Bulletin 46 is to augment the current knowledge about concrete and concrete structures under fire, not only for the design of new structures, but also for the analysis and repair of existing fire-damaged structures. Both structural and materials issues are examined, and the results of the most recent research activities on the structural performance of concrete subjected to fire are reported. Special attention is paid to the indirect actions caused by the restrained thermal deformations and several basic examples show how a local fire influences global structural behaviour. fib Bulletin 46 is intended for use by practicing engineers to improve their understanding of the behaviour of concrete structures in fire and thereby produce better and safer design standards.

Book Synopsis Analysis of Reinforced Concrete Beams Subjected to Fire by : Bruce R. Ellingwood
Download or read book Analysis of Reinforced Concrete Beams Subjected to Fire written by Bruce R. Ellingwood and published by . This book was released on 1976 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for analytically predicting the behavior of simply supported reinforced concrete beams subjected to fire are presented. This is generally a two-step process involving a thermal analysis followed by a stress analysis. This study emphasizes the latter, wherein the determination of moment-curvature-time relationships for the beam cross section incorporates the temperature-dependent strength degradation in the steel and concrete as well as thermal and creep strains. The sensitivity of the predictions to various phases of analytical modeling is investigated to establish the parameters most important for the prediction of beam behavior and to indicate where additional data should be gathered. A comparison of predicted behavior with that observed in fire tests shows excellent agreement when realistic reinforcement temperature histories are used.

Book Synopsis Composite Steel and Concrete Structures: Fundamental Behaviour (Second Edition) by : D.J. Oehlers

This book was released on 2013-10-22 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the analysis and behaviour of composite structural members that are made by joining a steel component to a concrete component. The emphasis of the book is to impart a fundamental understanding of how composite structures work, so engineers develop a feel for the behaviour of the structure, often missing when design is based solely by using codes of practice or by the direct application of prescribed equations. It is not the object to provide quick design procedures for composite members, as these are more than adequately covered by recourse to such aids as safe load tables. The subject should therefore be of interest to practising engineers, particularly if they are involved in the design of non-standard or unusual composite structures for buildings and bridges, or are involved in assessing, upgrading, strengthening or repairing existing composite structures. The fundamentals in composite construction are covered first, followed by more advanced topics that include: behaviour of mechanical and rib shear connectors; local buckling; beams with few shear connectors; moment redistribution and lateral-distortional buckling in continuous beams; longitudinal splitting; composite beams with service ducts; composite profiled beams and profiled slabs; composite columns; and the fatigue design and assessment of composite bridge beams.

Book Synopsis Behaviour and Design of Steel and Composite Connections in Fire by : Mostafa Jafarian
Download or read book Behaviour and Design of Steel and Composite Connections in Fire written by Mostafa Jafarian and published by CRC Press. This book was released on 2023-02-17 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under fire conditions, the strong interactions in structures result in different load carrying mechanisms and drastic redistributions of internal forces in structural members, which are concentrated at and transferred via connections. Fire safety depends on the performance of these connections, including their temperature distribution and load-carrying mechanisms, and good performance ensures structural robustness in fire. Behaviour and Design of Steel and Composite Connections in Fire is the only dedicated book on fire performance of connections in steel and composite structures. Recent experimental and numerical studies, from individual elements to whole, real-scale structures, have indicated that connections are among the most vulnerable and critical parts of these structures. This book synthesises the research findings on this important subject and explains the essential features in an accessible way in one single source. The book is ideal for researchers, structural engineers and fire protection engineers in their applications of performance-based fire engineering.
