Structural Stability - Theory Implementation


Author: W.F. Chen & E.M. Lui | Size: 13.66 MB | Format: PDF | Quality: Unspecified | Publisher: Elsevier | Year: 1987 | pages: 490 | ISBN: 0135005396
 
Structural Stability: Theory and Implementation is a practical work that provides engineers and students in structural engineering or structured mechanics with the background needed to make the transition from fundamental theory to practical design rules and computer implementation. Beginning with the basic principles of structural stability and basic governing equations,Structural Stability is a concise and comprehensive introduction that applies the principlesand theory of structural stability (which are the basis for structural steel design) to the solution of practical buildingframe design problems. Special features include:
  • modern theories of structural stability of members and frames, and a discussion of how these theories may be utilized to provide design rules and calculation techniques for design
  • important governing equations and the classical solutions used in design processes
  • examples of analytical and numerical methods selected as the most useful and practically applicable methods available
  • detailed information on the stability design rules of the 1986 AISC/LRFD Specifications for the design, fabrication, and erection of structural steel for buildings
  • dual units (SI and English) with most of the material presented in a non-dimensional format
  • fully worked examples, end-of-chapter problems, answers to selected problems, and clear illustrations and tables
Am outstandingly practical resource, Structural Stability offers the reader an understanding of the fundamental principles and theory of structural stability not only in an idealized, perfectly elastic system, but also in an inelastic, imperfect system representative of the actual structural systems encountered in engineering practice.

Hypothetical Earthquake Ground Shaking Estimation for Performance-Based Design



Earthquake engineering design of buildings increasingly is using nonlinear dynamic analysis to demonstrate buildingperformance. One requirement of the nonlinear dynamic procedure is the selection and manipulation of ground motions appropriate to design hazard level.

Seismic hazard due to ground shaking should be determined considering the location of the building with respect to causative faults, the regional site-specific geologic characteristics, and the selected earthquake hazard level. In general, the seismic hazard should include earthquake-induced geologic site hazards in addition to ground shaking. 

The discussion here is limited to ground shaking hazard.

Fundamentals of Structural Engineering



Author: Connor, Jerome J., Faraji, Susan | Size: 48,25 MB | Format: PDF | Quality: Original preprint | Publisher: Springer | Year: 2013 | pages: 1143 | ISBN: 9781461432623 

Fundamentals of Structural Engineering provides a balanced, seamless treatment of both classic, analytic methods and contemporary, computer-based techniques for conceptualizing and designing a structure. The book’s principle goal is to foster an intuitive understanding of structural behavior based on problem solving experience for students ofcivil engineering and architecture who have been exposed to the basic concepts of engineering mechanics and mechanics of materials. Distinct from many undergraduate textbooks focused mainly on either teaching manual analysis methods and applying them to simple, idealized structures—an approach based on the premise that intuition about structural behavior is developed as one works through the manual computations which, at times, may seem exhaustive, or reformulating structural analysis methods in terms of matrix notation—an approach that provides the basis for developing and understanding computer software codes, but does not contribute toward developing intuition about structural behavior. The authors of this text recognize the notion that engineers reason about behavior using simple models and intuition they acquire through problem solving. The approach adopted in this text develops this type of intuition through by presenting extensive, realistic problems and case studies together with computer simulation, allowing rapid exploration how a structure responds to changes in geometry and physical parameters. The integrated approach employed in Fundamentals of Structural Engineering offers comprehensive preparation for students and authoritative reference for practitioners of structural engineering.

Methods for Earthquake Analysis


 
Author: Helge Dørheim | Size: 10.5 MB | Format: PDF | Quality: Unspecified | Publisher: NorwegianUniversity of Science and Technology | Year: 2012 | pages: 90

Based on the need for effective solutions of structures response to seismic loading, this thesis includes the theoretical background, and explanation of several methods. There are many theories in the community, but the ones chosen to be looked closer at here are Modal response spectrum analysis for symmetric and asymmetric plan structures, Modal Pushover Analysis for symmetric and asymmetric plan structures and Linear and Non-Linear Response History Analysis. The theory has been adapted from published papers and books on the topic.
The report is divided into three main sections, numerical methods for solving of dynamic problems, elastic analysis and inelastic analysis. The chapters on Elastic and Inelastic analysis are further divided into sections on symmetric and asymmetric plan.
Elastic analyses by hand calculations and SAP2000 have been performed on a 2D-frame, a SAP2000 Elastic Response spectrum analysis has been performed on a 3D-frame, and an inelastic modal pushover analysis in SAP2000 has been performed on a 2D frame.
The target for this inquiry is to discover advantages and disadvantages in the different methods and comparing them.

Alternate Path Method in Progressive Collapse Analysis



As a result of the increasing number of terrorist attacks registered against American facilities in the United States or abroad, United States government agencies continue to improve the design of their buildings to make them safer and less vulnerable to terrorist attacks. One of the factors typically considered in designing safer buildings and structures, is their ability to prevent total collapse after the loss of load-carrying components (Progressive Collapse) resulting from a terrorist attack. The consequences of not having a building capable of reducing the potential for progressive collapse could be catastrophic, as it was the case of the Oklahoma City bombing in 1995 where 42% of the Alfred P. Murrah Federal Building was destroyed by progressive collapse and only 4% by the explosion or blast. This attack claimed 168 lives and left over 800 injured. Over the last 10 years, two United States government agencies have developed guidelines for the design of their structures to resist progressive collapse: (1) The General Services Administration, "Progressive Collapse Analysis and Design Guidelines," (GSA Guidelines) and (2) The Department of Defense Unified Facilities Criteria 4-023-03 "Design of Buildings to Resist Progressive Collapse" (UFC 4-023-03). Within both approaches, the main direct design procedure is the Alternate Path (AP) method, in which a structure is analyzed for collapse potential after the removal of a column or section of wall. Different analytical procedures may be used, including Linear Static (LS), Nonlinear Static (NLS), and Nonlinear Dynamic (NLD). Typically, NLD procedures give better and more accurate results, but are more complicated and expensive. As a result, designers often choose static procedures, which tend to be simpler, requiring less labor. As progressive collapse is a dynamic and nonlinear event, the load cases for the static procedures require the use of factors to account for inertial and nonlinear effects, similar to the approach used in ASCE Standard 41 "Seismic Rehabilitation of Existing Buildings" (ASCE 41). A number of inconsistencies have been indentified in the way the existing guidelines applied dynamic and non-linear load factors to their static approaches. As part of an existing effort to update the existing guidelines, this study used SAP2000 to perform several AP analyses on a variety of Reinforced Concrete and Steel Moment Frame buildings to investigate the magnitude and variation of the dynamic and non-linear load increase factors. The study concluded that the factors in the existing guidelines tend to yield overly conservative results, which often translate into expensive design and retrofits. This study indentified new load increase factors and proposes a new approach to utilize these factors when performing AP analyses for Progressive Collapse.

Design of Anchorages in Concrete



Author: FIB | Size: 5.2 MB | Format: PDF | Quality: Scanner | Publisher: FIB | Year: 2011 | pages: 280 | ISBN: 978-2-88394-098-7

Despite the widespread use of cast-in-place and post-installed anchors in construction, the overall level of understanding in the engineering community regarding their behaviour remains quite limited. Furthermore, since the publication of the original CEB design guide, “Design of Fastenings in Concrete”, ongoing research and additionalapplication experience has led to an improved understanding and deepened knowledge in various areas of fastening technology.

Fib Bulletin 58 therefore represents a substantial revision of the original 1997 guide. It addresses a variety of loading types and failure modes and takes into account the current state of the art for anchorages in new construction as well as for their use in the repair and strengthening of existing concrete structures.

Fib Bulletin 58 provides a method for the design of the anchorage and additional rules for the design of the concrete member to which the load is transferred. The specified provisions are based on the currently available research.
