Available in PDF, EPUB and Kindle. Book excerpt: Steel columns are used in many high rise as well as industrial constructions. These columns act as the main load carrying member. In this paper results of analytical studies carried out to evaluate the performance mechanisms of steel columns exposed to fire have been presented. The finite element method is used to analyse the buckling behaviour of geometrically perfect steel columns at elevated temperatures. The column behaviour up to collapse was investigated considering geometric as well as material non-linearities. The analysis includes non-linear material characteristics as a function of temperature. The importance of proper idealisation of stress strain temperature behaviour has been brought out. The buckling characteristics of columns have been analysed for continuous stress-strain-temperature material behaviour as well as elasto-plastic bilinear idealisations. The influence of slenderness ratios was found to control the buckling behaviour of columns at elevated temperatures. Solutions have been provided to evaluate critical stresses of columns with different end fixity conditions. The factors which control the performance of columns exposed to fire have been discussed Comparisons have been made with other analytical approaches and available experimental data. It is believed that the fire safety engineer will be benefited from these studies.

This book was released on 2015-02-25 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis studied the effect of aging of intumescent coatings (ICs) on the reliability of protected steel columns in fire condition and developed a probabilistic approach to assess the service life of ICs applied on steel columns. In the study, Monte Carlo simulations were conducted to obtain the reliability index or failure probability of steel columns protected by ICs subjected to compartment fires. The effect of aging of intumescent coatings on the failure probability of protected steel columns was investigated by using variable insulation property of intumescent coatings in the simulation. The test data on aging effect on insulation property of intumescent coatings from literature was used. Based on the reliability analysis, a probabilistic approach is given to determine the service life of intumescent coatings for steel columns. In that approach, the failure probability of the protected steel columns is compared with the target probability of the structural fire design. The approach can also be used for probabilistic analysis of steel columns protected by conventional inert fire protection materials.

Available in PDF, EPUB and Kindle. Book excerpt: Concrete-filled stainless steel tubular (CFSST) columns are increasingly used in modern composite construction due to their high strength, high ductility, high corrosion resistance, high durability and aesthetics and ease of maintenance. Thin-walled CFSST columns are characterized by the different strain-hardening behavior of stainless steel in tension and in compression, local buckling of stainless steel tubes and concrete confinement. Design codes and numerical models often overestimate or underestimate the ultimate strengths of CFSST columns. This book presents accurate and efficient computational models for the nonlinear inelastic analysis and design of CFSST short and slender columns under axial load and biaxial bending. The effects of different strain-hardening characteristics of stainless steel in tension and in compression, progressive local and post-local buckling of stainless steel tubes and concrete confinement are taken into account in the computational models. The numerical models simulate the axial load-strain behavior, moment-curvature curves, axial load-deflection responses and axial load-moment strength interaction diagrams of CFSST columns. The book describes the mathematical formulations, computational procedures and model verifications for circular and rectangular CFSST short and slender columns. The behavior of CFSST columns under various loading conditions is demonstrated by numerous numerical examples. This book is written for practising structural and civil engineers, academic researchers and graduate students in civil engineering who are interested in the latest computational techniques and design methods for CFSST columns.

Download or read book Design Solutions for Steel Beams Exposed to Fire written by Vute Chandrasekaran and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Steel beam and concrete floor assembly systems have been used in many high rise as well as industrial constructions. These systems support the entire structural loading. Normally in the event of fire occurrence the steel beam concrete floor assembly is exposed to fire from the underside of the floor slab. The analysis of the steel beam and the concrete floor system exposed to fire has not been dealt with adequately in the literature. Herein, nonlinear finite element analysis has been adopted to study the performance of the steel beam concrete slab system exposed to fire. The study is done in two parts. The first part deals with the heat transfer mechanisms of the structural assembly. The variations of properties such as thermal conductivity in the heat transfer mechanism have been taken into account along with radiation and convection. Also, stress-deformation analysis of the structural component has been performed using non linear finite element analysis techniques. Both material and geometric nonlinearities have been incorporated in the studies. The analyses were performed for the standard time temperature curves described by ISO 834. The paper describes the various aspects of the heat transfer mechanisms of the structural assembly. The variations of the temperature at different locations have been provided. The paper discusses in detail the stress deformation behaviour of the steel beam and concrete slab system exposed to fire from the underside of the slab. Information beneficial to the designer in evaluating the performance of steel beams supporting the concrete slab exposed to fire has been provided in the paper.

Available in PDF, EPUB and Kindle. Book excerpt: Major events—notably the Broadgate fire in London, New York’s World Trade Center collapse, and the Windsor Tower fire in Madrid—as well as the enlightening studies at the Cardington fire research project have given international prominence to performance-based structural fire engineering. As a result, structural fire engineering has increasingly attracted the interest not only of fire and structural engineers but also of researchers and students. And studies in recent years have generated a vast number of findings. Performance-Based Fire Engineering of Structures summarizes the latest knowledge on performance-based approaches to structural fire engineering, enabling readers to critically assess research in the field. Whereas most recent books have been mainly concerned with dissemination of principles encapsulated in established codes of practice such as the Eurocodes, this work addresses in depth: Global structural behaviour and modelling Progressive collapse of structures in fire and the importance of connection robustness The integrity of compartmentation in fire Structural fire engineering under realistic fire conditions and its implications for material properties The limitations of research results and design methods The unexploited potential for advanced fire engineering design This authoritative book draws on the work of internationally active researchers who were core members of the European Network project’s COST C26 working group on fire resistance. It helps readers develop a thorough understanding of how to use advanced fire engineering design to improve structural safety and reduce construction costs.
