This document defines the minimum experimental evidence that can be deemed adequate to attempt to validate the use, in regions of high seismic risk or in structures assigned to satisfy high seismic performance or design categories, of weak beam/strong column moment frames not satisfying fully the prescriptive requirements of Chapter 21 of ACI 318-99. This document consists of both a Standard and a Commentary that is not part of the Standard. The document has been written in such a form that its various parts can be adopted directly into Sections 21.0, 21.1, and 21.2.1 of ACI 318-99 and the corresponding sections of ACI 318R-99. Among the subjects covered are requirements for: procedures that shall be used to design test modules; configurations for those modules; test methods; test reports; and determination of satisfactory performance.
The Commentary describes some of the considerations of the Innovation Task Group in developing the Standard. The section numbering for the Commentary is the same as that for the Standard, with numbers preceded by an “R” to distinguish them from the corresponding section numbers of the Standard.
The Commentary references documentary evidence, additional to the references of Chapter 21 of ACI 318R-99, that supports the Standard. Consistent with the approach of ACI 318-99 and ACI 318R-99, no comparison is made, either in the body of the Standard or its Commentary, of research results for test modules satisfying ACI 318-99 with those for modules that, although not satisfying ACI 318-99, do satisfy the Standard. Such comparisons, both experimental and analytical, are available in the references of the Commentary.
Keywords: acceptance criteria; drift ratio; energy dissipation; lateral resistance;
moment frame; post-tensioning; precast concrete; prestressed concrete; seismic design; test module; toughness.

Structural Analysis: Skills for Practice encourages engineering students to develop their intuition and the habit of evaluating the reasonableness of structural analysis results. The author presents examples and homework problems that incorporate a consistent thought process structure―guess, calculate, and evaluate their results―helping students develop the metacognitive skill of thinking about their own thought process. The text presents content not seen in other structural analysis books that students need to know to pass their licensure exam and frames ideas in the context of how they will apply it on the job. Drawing upon the evaluation skills gathered from a six year project with experienced structural engineers, Hanson’s Structural Analysis helps students learn skills to transition from novice to expert faster and become more competent in their careers.

The endurance time method (ETM) is a seismic analysis procedure in which intensifying dynamic excitations are used as the loading function, and it provides many unique benefits in the design of structures. It can largely reduce the computational effort needed for the response history analysis of structures. This aids in the practical application of response history-based analysis in problems involving very large models and/or requiring numerous analyses to achieve optimal design goals. A single response history analysis through ETM provides an estimate of the system response at the entire range of seismic intensities of interest, thus making it ideal for applications such as seismic risk assessment, life-cycle cost analysis, and value-based seismic design. Conceptual simplicity also makes ETM a useful tool for preliminary response history analysis of structural systems.
Features:
Presents full coverage of the subject from basic concepts to advanced applied topics.
Provides a coherent text on endurance time excitation functions that are essential in endurance time analysis.
Seismic Analysis and Design using the Endurance Time Method serves as a comprehensive resource for students, researchers, and practicing structural engineers who want to familiarize themselves with the concepts and applications of the endurance time method (ETM) as a useful tool for dynamic structural analysis.

Structural Design for Physical Security State of the Practice (MOP 142)
Author(s)/Editor(s): American Society of Civil Engineers, Peggy Van Eepoel, Sharon M. Gallant | Size: 12.8 MB| Format:PDF| Quality:Original preprint| Publisher: American Society of Civil Engineers| Year: 2021| pages: 471 | ISBN: ISBN-10:0784415498 ISBN-13:978-0784415498
Prepared by the Task Committee on Structural Design for Physical Security of the Blast, Shock, and Impact Committee of the Dynamic Effects Technical Administration Committee of the Structural Engineering Institute of ASCE
Structural Design for Physical Security, MOP 142, provides an overview of the typical design considerations encountered in new construction and renovation of facilities for physical security. The constant change in threat tactics and types has led to the need for physical security designs that account for these new considerations and anticipate the environment of the future, with flexibility and adaptability being priorities. This Manual of Practice serves as a replacement for the 1999 technical report Structural Design for Physical Security: State of the Practice and is intended to provide a roadmap for designers and engineers involved in physical security. It contains references to other books, standards, and research.
Topics include:
Threat determination and available assessment and criteria documents,
Methods by which structural loadings are derived for the determined threats,
Function and selection of structural systems,
Design of structural components,
Function and selection of window and façade components,
Specific considerations for retrofitting structures,
Testing methodologies, and
Bridge security.
This book will be a valuable resource to structural engineers and design professionals involved with projects that have physical security concerns related to explosive, ballistic, forced entry, and hostile vehicle threats.

Author(s)/Editor(s): Bernhard Wietek | Size: 11.8 MB| Format:PDF| Quality:Original preprint| Publisher: Springer| Year: September 3, 2021 | ISBN: 9783658344818
This new edition of the book helps the user to correctly use fiber-reinforced concrete as a building material in accordance with its properties in order to create a long-lasting building to create a long-lasting building for the client at low cost. The chapters on chapters on the properties, design and processing of fiber-reinforced concrete.Fiber-reinforced concrete as an extension of concrete offers considerable advantages for building practice, which, based on the material properties, allow a very long service life.
Fiber-reinforced concrete is particularly suitable for an aggressive environment such as salt exposure, since corrosion can be completely avoided.Particular attention is also paid to the shrinkage cracks that occur in the concrete and how they can be and how these can be avoided when using fibers.
Fiber-reinforced concrete, with its material properties, acts over the entire cross section cross-section in the non-cracked state and thus also offers protection against internal protection against internal destruction. It is a building material that achieves its full static effect in the non-cracked state similar to most other building materials such as wood, steel, glass, etc.
This book is a translation of the original German 3rd edition Faserbeton by Bernhard Wietek, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
