Advanced Analysis and Design of Steel Frames


Book Description

Steel frames are used in many commercial high-rise buildings, as well as industrial structures, such as ore mines and oilrigs. Enabling construction of ever lighter and safer structures, steel frames have become an important topic for engineers. This book, split into two parts covering advanced analysis and advanced design of steel frames, guides the reader from a broad array of frame elements through to advanced design methods such as deterministic, reliability, and system reliability design approaches. This book connects reliability evaluation of structural systems to advanced analysis of steel frames, and ensures that the steel frame design described is founded on system reliability. Important features of the this book include: fundamental equations governing the elastic and elasto-plastic equilibrium of beam, sheer-beam, column, joint-panel, and brace elements for steel frames; analysis of elastic buckling, elasto-plastic capacity and earthquake-excited behaviour of steel frames; background knowledge of more precise analysis and safer design of steel frames against gravity and wind, as well as key discussions on seismic analysis. theoretical treatments, followed by numerous examples and applications; a review of the evolution of structural design approaches, and reliability-based advanced analysis, followed by the methods and procedures for how to establish practical design formula. Advanced Design and Analysis of Steel Frames provides students, researchers, and engineers with an integrated examination of this core civil and structural engineering topic. The logical treatment of both advanced analysis followed by advanced design makes this an invaluable reference tool, comprising of reviews, methods, procedures, examples, and applications of steel frames in one complete volume.




Advanced Analysis of Steel Frames


Book Description

The development of the limit state approach to design in recent years has focused particular attention on two basic requirements: accurate information regarding the behavior of structures throughout the entire range of loading up to the ultimate strength, and simple practical procedures to enable engineers to assess this behavior. This book satisfies these requirements by providing practical analysis methods for the design of steel frames. The book contains a wide range of second-order analyses: from elastic to inelastic, rigid to semi-rigid connections, and simple plastic hinge method to sophisticated plastic-zone method. Computer programs for each analysis are provided in the form of a floppy disk for easy implementation. Sample problems are described and user's manuals are well documented for each program developed in the book.

Book Description

This report presents formal guidelines for the use of second-order inelastic analysis in the design and assessment of steel framing systems.







Stability Design of Steel Frames


Book Description

Stability Design of Steel Frames provides a summary of the behavior, analysis and design of structural steel members and frames with flexibly-jointed connections. The book presents the theory and design of structural stability and includes extensions of computer-based analyses for individual members in space with imperfections. It also shows how connection flexibility influences the behavior and design of steel frames and how designers must consider this in a limit-state analysis and design procedure. The clearly written text and extensive bibliography make this a practical book for advanced students, researchers and professionals in civil and structural engineering, as well as a useful supplement to traditional books on the theory and design of structural stability.

Toward advanced analysis in steel frame design


Book Description

The trends for analysis and design of steel frames are indicated in this dissertation. The current practice consists of applying the first-order elastic analysis with amplification factors or second-order elastic analysis in combination with the AISC-LRFD interaction equations. Determination of the effective length factors and individual member capacity checks are necessary to select adequate structural member sizes. The direct analysis method is a second-order elastic analysis approach that eliminates the determination of effective length factors from the current AlSC-LRFD method. Unsupported member length is used to calculate the axial strength of a member. Equivalent notional loads and/or modified stiffness are applied together with the external loads to account for the effects of initial out-of-plumbness and inelastic softening. For both AlSC-LRFD and direct analysis methods, a structure is analyzed as a whole, but the axial and flexural strength of each member is examined individually. Inelastic redistribution of internal forces in the structural system cannot be considered. As a result, determined member forces are not correct and more conservative member sizes will be obtained. Moreover, member-based approaches cannot predict structural behaviors such as failure mode and overstength factor. The advanced analysis method considered in this work is a second-order refined plastic hinge analysis in which both effective length factors and individual member capacity checks are not required. In addition, advanced analysis is a structure systembased analysis/design method that can overcome the difficulties of using member-based design approaches. Thus, advanced analysis is a state-of-the-art method for steel structure design. Several numerical examples are provided to show the design details of all three methods. The design requirements corresponding to each analysis approach are illustrated in these examples. The pros and cons of each method are discussed by comparin.




LRFD Steel Design Using Advanced Analysis


Book Description

LRFD Steel Design Using Advanced Analysis uses practical advanced analysis to produce almost identical member sizes to those of the Load and Resistance Factor Design (LRFD) method. The main advantage of the advanced analysis method is that tedious and sometimes confusing separate member capacity checks encompassed by the AISC-LRFD specification equations are not necessary. Advanced analysis can sufficiently capture the limit state strength and stability of a structural system and its individual member directly. While the use of elastic analysis is still the norm in engineering practice, a new generation of codes is expected to adopt the advanced analysis methodology in the near future, leading to significant savings in design effort. In recent years, the continued rapid development in computer hardware and software, coupled with an increased understanding of structural behavior, has made it feasible to adopt the advanced analysis techniques for design office use. Drs. Chen and Kim, both experienced and respected engineers, contribute their expertise to this text, which is intended for both the graduate student and the practicing engineer. Previous knowledge of the subject is not necessary, but familiarity with methods of elastic analysis and conventional LRFD design is expected. The advanced analysis in the book is presented in a practical and simple manner, with attention directed to both analysis and design, emphasizing the direct use of the methods in engineering practice. This is a great introduction to an exciting new trend in structural engineering!




Plastic Analysis and Design of Steel Structures


Book Description

The plastic analysis method has been used extensively by engineers for designing steel structures. Simpler structures can be analyzed using the basic virtual work formulation, but more complex frames are evaluated with specialist computer software. This new book sets out a method for carrying out plastic analysis of complex structures without the need for specialist tools.The book provides an introduction to the use of linear programming techniques for plastic analysis. This powerful and advanced method for plastic analysis is important in an automated computational environment, in particular for non-linear structural analysis.A detailed comparison between the design codes for the United States and Australia and the emerging European Eurocodes enables practising engineers to understand the issues involved in plastic design procedures and the limitations imposed by this design method. Covers latest research in plastic analysis and analytical tools Introduces new successive approximation method for calculating collapse loads Programming guide for using spreadsheet tools for plastic analysis




Non-Linear Static and Cyclic Analysis of Steel Frames with Semi-Rigid Connections


Book Description

This book is devoted to the discussion and studies of simple and efficient numerical procedures for large deflection and elasto-plastic analysis of steel frames under static and dynamic loading. In chapter 1, the basic fundamental behaviour and philosophy for design of structural steel is discussed, emphasising different modes of buckling and the inter-relationship between different types of analysis. In addition to this, different levels of refinement for non-linear analysis are described. An introduction is also given to the well-known P-&dgr; and P-&Dgr; effects. Chapter 2 presents the basic matrix method of analysis and gives several examples of linear analysis of semi-rigid pointed frames. It is evident from this that one must have a good understanding of first-order linear analysis before handling a second-order non-linear analysis. In chapter 3, the linearized bifurcation and second-order large deflection are compared and the detailed procedure for a second-order analysis based on the Newton-Raphson scheme is described. Chapter 4 introduces various solution schemes for tracing of post-buckling equilibrium paths and the Minimum Residual Displacement control method with arc-length load step control is employed for the post-buckling analysis of two and three dimensional structures. Chapter 5 addresses the non-linear behaviour and modelling of semi-rigid connections while several numerical functions for description of moment versus rotation curves of typical connection types are introduced. The scope of the work in chapter 6 covers semi-rigid connections and material yielding to the static analysis of steel frames. Chapter 7 studies the cyclic response of steel frames with semi-rigid joints and elastic material characteristics. In the last chapter the combined effects of semi-rigid connections and plastic hinges on steel frames under time-dependent loads are studied using a simple springs-in-series model. For computational effectiveness and efficiency, the concentrated plastic hinge concept is used throughout these studies.
