Available in PDF, EPUB and Kindle. Book excerpt: Inelastic buckling is the most important failure mode of a steel beam column element subjected to compression force. In order to correctly predict this phenomenon, large rotations, large displacements and the plasticity of the section along the element must be considered. Several formulations have been proposed to model problems with three dimensional large displacements and rigid body dynamics. They are usually based in the Lagrangian or the Corotational methods and are primarily oriented to solve mechanical and aerospace problems, although some applications to structural stability do exist. Independently, several formulations have been developed to model plasticity: fiber elements, plastic flow theory and lumped plasticity are popular choices. In this dissertation a novel formulation capable of solving problems with displacement and material nonlinearities in a unified way is developed. Thus, the State Space approach is selected because all the basic equations of structures: equilibrium, compatibility and plasticity are solved simultaneously and thus the global and local states are mutually and explicitly dependent. To incorporate geometric nonlinearities, the Corotational approach, where rigid body motion and deformations are described separately, is adopted. To incorporate material nonlinearities, the formulation developed by Simeonov (1999) and Sivaselvan (2003) is included. In general, the set of equilibrium, compatibility and plasticity equations constitute a system of Differential Algebraic Equations (DAE). A procedure to solve such system exists and is implemented in the package IDA (Implicit Differential Algebraic solver) developed at the Lawrence Livermore National Laboratory (LLNL), which is used to solve the problem numerically. An experimental study on "zipper frames" was conducted to assess the accuracy of the proposed formulation. A "zipper frame" is a chevron braced frame where the beam to brace connections are linked through columns, called "zipper columns". The failure mode of a "zipper frame" is the successive inelastic buckling of its braces. Three shake table tests of a three stories "zipper frame" were performed at the UB-NEES laboratory. A model of the first story of the "zipper frame" was analyzed with the new formulation and its results compared to experimental data. It is found that the new formulation can reproduce the features of the test and it is very sensitive to all the model parameters. Results are presented

Available in PDF, EPUB and Kindle. Book excerpt: The use of COSMOS for the analysis and solution of structural dynamics problems is introduced in this new edition. The COSMOS program was selected from among the various professional programs available because it has the capability of solving complex problems in structures, as well as in other engin eering fields such as Heat Transfer, Fluid Flow, and Electromagnetic Phenom ena. COSMOS includes routines for Structural Analysis, Static, or Dynamics with linear or nonlinear behavior (material nonlinearity or large displacements), and can be used most efficiently in the microcomputer. The larger version of COSMOS has the capacity for the analysis of structures modeled up to 64,000 nodes. This fourth edition uses an introductory version that has a capability limited to 50 nodes or 50 elements. This version is included in the supplement, STRUCTURAL DYNAMICS USING COSMOS 1. The sets of educational programs in Structural Dynamics and Earthquake Engineering that accompanied the third edition have now been extended and updated. These sets include programs to determine the response in the time or frequency domain using the FFf (Fast Fourier Transform) of structures modeled as a single oscillator. Also included is a program to determine the response of an inelastic system with elastoplastic behavior and a program for the development of seismic response spectral charts. A set of seven computer programs is included for modeling structures as two-dimensional and three dimensional frames and trusses.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: It is evident that European earthquake engineering research and design practice is assuming a role of increasing importance on the international scene. This is primarily due to two considerations; firstly the emergence of a core of European earthquake engineers who are co-operating on a long-term basis for the development of seismic design criteria specific to the European environment and secondly the identification of new problems in existing design practice in the USA and in Japan. It is in this context that European earthquake engineering activities and publications are eagerly observed and awaited by the international community. Includes a compact set of papers from leading research institutions, laboratories and companies in Europe, with a healthy number of contributions from elsewhere. It represents the European state-of-the-art and practice in earthquake testing, analysis & design of civil engineering works as well as strong-motion & hazard studies.
