This book was released on 2023-05-26 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2014 in the subject Engineering - Civil Engineering, grade: 9, , course: Advanced Steel Structures, language: English, abstract: This dissertation presents three various advanced analysis approaches which can capture accurately and efficiently the ultimate strength and behavior of steel framed structures with nonlinear beam-to-column connections subjected to static and dynamic loadings. Three major sources of nonlinearity are considered in the analyses as follows: (1) material nonlinearity; (2) geometric nonlinearity; and (3) connection nonlinearity. Three types of nonlinear beam-column element formulation considering both geometric and material nonlinearities are coded into two nonlinear structural analysis programs: (1) Nonlinear Structural Analysis Program (NSAP) – 2-D plastic-zone finite element; (2) Practical Advanced Analysis Program (PAAP) – 3-D refined plastic-hinge element and 3-D plastic-fiber element. Three types of steel frames analyzed by the proposed program are: (1) rigid frames – beam-to-column connections are fully rigid; (2) linear semi-rigid frames – beam-to-column connections have constant stiffness; and (3) nonlinear semi-rigid frames – beam-to-column connections have continuously variable stiffness. Three types of analysis can be performed are: (1) nonlinear inelastic static analysis; (2) nonlinear elastic and inelastic time-history analysis; and (3) free vibration analysis. Three main resources of damping are taken into account in the proposed programs are: (1) hysteretic damping due to inelastic material; (2) structural viscous damping employing Rayleigh damping; (3) hysteretic damping due to nonlinear beam-to-column connections. Two computer programs are developed: (1) Nonlinear Structural Analysis Program (NSAP) – written in the C++ programming language; (2) Practical Advanced Analysis Program (PAAP) – written in the FORTRAN 77 programming language. They are verified for accuracy and computational efficiency by comparing predicted results with those generated by the commercial finite element analysis packages of ABAQUS and SAP2000, and other results available in the literature. Through several numerical examples, the proposed program (PAAP) proves to be a reliable and efficient tool for daily practice design in lieu of using costly and time-consuming commercial software.

Available in PDF, EPUB and Kindle. Book excerpt: The first objective of this dissertation is the development of a three-dimensional hysteretic model capable of representing the behavior of typical frame members. A macro-modeling approach is adopted, the essence of which is to define the constitutive relations at a control section directly in terms of stress resultants and strains. The derivation relies on the premise that the underlying material behavior can be represented by a parallel-plasticity model. The connection between the fundamental stress-strain law and the section stress resultant-strain relations is rationalized from that perspective. The model is designed as a constitutive relation with internal variables. The evolution equations are postulated using non-associated flow rule with the ultimate-yield locus of the section serving as a plastic potential function. The latter is represented by an axial force-biaxial moment interaction surface in hysteretic force space. A new parametric equation of a general interaction surface is introduced to provide a versatile tool for modeling triaxial effects in frame members. It is also demonstrated that several popular one- and two-dimensional hysteretic models can be regarded as particular cases of the proposed model. The loading/unloading criteria of the two-dimensional versions are shown inadequate and a new loading/unloading criterion is proposed. The constitutive model is then used to define the behavior at the control sections of a nonlinear beam-column element. The principle of virtual forces is employed to derive the nodal force-displacement relationship embodied by the flexibility matrix. This approach exploits the internal determinancy of frame members under any boundary conditions - a quality allowing exact interpolation of the element force field from the nodal actions. The element is developed in the setting of a stiffness-based incremental solution of the governing equations. The specific contribution is the introduction of a novel aspect in the state determination procedure. The main idea is to merge the equilibrium unbalances at the control sections from the current global iteration with the incremental internal forces in the next one. Another goal of the dissertation is the conceptual design of an algorithm for solving finite-element problems in state space. The key concept is to solve the structure equations of motion and the element constitutive relations simultaneously in time. Specific advances are made toward systematizing the task of defining the state of a general element and postulating its evolution. Guidelines are provided for selection of state variables for various combinations of formulation types and constitutive models. The concepts involved in the creation of a new element are illustrated through the definition of an inelastic frame member model, operating in the setting of the state-space method. The final chapter of this dissertation presents analytical studies of a typical long multi-span highway bridge for spatially varying ground motion of the 1994 Northridge earthquake. The primary objective of the study is to qualify and quantify the effects of the non-synchronous excitation. The numerous cases involved in the study are analyzed using the modeling and analysis tools of the computational platform IDARC-BRIDGE. Based on these results, the relative importance of factors that have been shown to affect the behavior of highway bridges is weighed and the dominant influence on the response is identified.

This book was released on 2000-05-19 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.
