Book excerpt: Following recent events such as the World Trade Center building collapse and the Cardington large scale structural fire research program, the fire behavior of connections has now become an important research subject. This thesis presents the results of experimental, numerical and theoretical studies into the behavior of simple welded fin-plate to concretefilled tubular (CFT) columns loaded by tensile or shear force. Such connections represent a simple single-sided joint solution to steel CFTs which are considered an attractive and robust structural element. Experiments have been performed at both ambient and elevated temperatures against the results of which numerical finite element models have been validated. The ranges of parameters encompassed by the tests include column cross-section shape; column and finplate thickness; concrete in-fill; elevated temperatures and connection lever arm. The observed failure modes include fracture of the fin-plate and tearing out of the tube around the welds. By considering the results of previously published research, the current design method for similar connections under purely tensile load, in CIDECT Guide 9, based on a deformation limit of 3% of the tube width is shown to be inadequate when evaluating the ultimate strength of such connections. By comparing the results from the current test program which failed in the fin-plate with Eurocode guidance for failure of a fin-plate alone under shear and bending load it is shown that the column face influences the overall connection strength regardless of failure mode. Concrete in-fill is observed to significantly increase the strength of connections over empty specimens, and circular column specimens were observed to exhibit greater strength than similarly proportioned square columns. When validating the numerical model against elevated temperature tests it was found that the strength reduction factors suggested by Eurocode for steel at elevated temperature are appropriate. The numerical models developed have been used to perform extensive parametric studies from which simple hand calculation methods have been developed for evaluating the strength of the column component of square CFTs under either tensile or shear load imparted through a fin-plate connection. The simple hand calculation procedures are based upon defining a rigid plate deformation pattern for the connection and then applying the internal work principle. For connections under shear load a method is presented for combining the column failure load with the fin-plate failure derived from existing Eurocode guidance. Both simple hand calculation methods are compared favorably with available test results. A limited number of tests and numerical validation have also been performed for reverse channel to CFT connections loaded in shear at both ambient and elevated temperatures.

Abstract: Abstract of thesis entitled BEHAVIOUR OF HIGH STRENGTH STEEL COLUMNS AT ELEVATED TEMPERATURES Submitted by Ju Chen for the degree of Doctor of Philosophy at The University of Hong Kong in April 2007 In this study, the structural behaviour of high strength steel columns at elevated temperatures is investigated. The current fire resistant design rules for steel columns in most of the specifications are generally based on the investigation of hot-rolled steel having normal strength. Although similarities between the conventional normal strength and high strength steel exist, there is sufficient diversity in their mechanical properties for different treatments in design. Therefore, there is a need to develop the design rules of high strength steel columns at elevated temperatures. Material properties play an important role in the performance of steel structural members. Hence, an extensive material test program was first performed on high strength steel at elevated temperatures. The high strength steel includes cold-formed steel, stainless steel as well as quenched and tempered carbon steel. Structural carbon steel having normal strength was also tested for comparison. The mechanical properties and stress-strain curves of the tested steel were obtained and compared with predictions from the American, Australian, British and European specifications. In addition, equations predicting the mechanical properties and stress-strain curve model for the tested materials at elevated temperatures were proposed. The column behaviour of cold-formed steel built-up closed sections with intermediate web stiffeners at normal room temperature was investigated. The test results were compared with the design strengths obtained using the direct strength method. An accurate and reliable finite element model of cold-formed steel built-up columns was developed and verified against the test results. A parametric study was carried out using the verified finite element model. Design rules for cold-formed steel built-up closed section columns at normal room and elevated temperatures modified from the direct strength method were proposed. The behaviour of cold-formed steel lipped channel columns at elevated temperatures has been investigated using finite element method. The suitability of the effective width method and direct strength method for cold-formed steel lipped channel columns at elevated temperatures was evaluated. The behaviour of quenched and tempered high strength carbon steel columns at elevated temperatures was also investigated. The finite element analysis results were compared with the design strengths using the American, Australian and European specifications. Generally, it is shown that the effective width method and direct strength method using the reduced material properties conservatively predicted the column strengths.

Download or read book Concrete Filled Stainless Steel Tubular Columns written by Vipulkumar Patel and published by CRC Press. This book was released on 2018-12-07 with total page 132 pages. 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 Concrete filled Tubular Members and Connections written by Xiao-Ling Zhao and published by CRC Press. This book was released on 2017-05-31 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using steel and concrete together utilizes the beneficial material properties of both elements. Concrete filled steel tubes represent a good example of a concrete - steel composite structure, and are particularly useful as columns in high rise buildings and bridge piers. They can be used in a range of fields, from civil and industrial construction through to the mining industry. Several aspects of concrete filled tubes have received little coverage in existing design standards, design guides or relevant books, but are addressed here: construction methods or quality and their effect on performance, confinement, creep effects, pre-load effects, size effects, seismic behaviour and post-fire behaviour, worked examples under practical conditions, numerical simulations, mechanics models, concrete-filled double skin tubes, SCC(self-consolidating concrete)-filled tubes, HPHSC (high performance high strength concrete)-filled tubes, high strength steel and thin-walled tubes filled with concrete, and fiber reinforced polymer strengthening of concrete filled tubes. This book not only summarizes the research performed to date on concrete-filled tubular members and connections but also compares the design rules in various standards (Eurocode 4, AISI-LRFD, ACI, AIJ and Chinese Standard), and provides design examples. An invaluable guide for professionals and a detailed source of information for graduate students and beyond.

Download or read book Fire Safety Engineering Design of Structures Third Edition written by John A. Purkiss and published by CRC Press. This book was released on 2013-12-05 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing structures to withstand the effects of fire is challenging, and requires a series of complex design decisions. This third edition of Fire Safety Engineering Design of Structures provides practising fire safety engineers with the tools to design structures to withstand fires. This text details standard industry design decisions, and offers expert design advice, with relevant historical data. It includes extensive data on materials’ behaviour and modeling -- concrete, steel, composite steel-concrete, timber, masonry, and aluminium. While weighted to the fire sections of the Eurocodes, this book also includes historical data to allow older structures to be assessed. It extensively covers fire damage investigation, and includes as far back as possible, the background to code methods to enable the engineer to better understand why certain procedures are adopted. What’s new in the Third Edition? An overview in the first chapter explains the types of design decisions required for optimum fire performance of a structure, and demonstrates the effect of temperature rise on structural performance of structural elements. It extends the sections on less common engineering materials. The section on computer modelling now includes material on coupled heat and mass transfer, enabling a better understanding of the phenomenon of spalling in concrete. It includes a series of worked examples, and provides an extensive reference section. Readers require a working knowledge of structural mechanics and methods of structural design at ambient conditions, and are helped by some understanding of thermodynamics of heat transfer. This book serves as a resource for engineers working in the field of fire safety, consultants who regularly carry out full fire safety design for structure, and researchers seeking background information. Dr John Purkiss is a chartered civil and structural engineer/consultant and former lecturer in structural engineering at Aston University, UK. Dr Long-Yuan Li is Professor of Structural Engineering at Plymouth University, UK, and a Fellow of the Institution of Structural Engineers.
