NRCC Guidelines for Seismic Evaluation of Existing Buildings
Author: D.E. Allen, principal investigator, | Size: 8.3 MB | Format:PDF | Quality:Original preprint | Publisher: NRCC (National Research Council of Canada) | Year: December 1993 | pages: 166 | ISBN: ISBN 0-660-15382-3
These Guidelines are a technical manual that offers guidance to engineers in the seismic evaluation of existing buildings. These Guidelines are addressed to well-qualified structural engineers, but who are not necessarily experts in earthquake engineering. The objective of the Guidelines is to identify typical structural deficiencies that have been observed in past earthquakes to lead to failure and falling of structural components and to partial or total collapse, with an attendant injury or loss of life. The methodology and criteria of the Guidelines are based on life safety, not property damage, and therefore satisfy the basic life-safety objective of the National Building Code. They do not, however, comply with specific requirements of the National Building Code, which are appropriate for the design of new buildings. The Guidelines present a set of questions that are designed to uncover weaknesses of the particular building being evaluated. The questions are in the form of Evaluation Statements that relate to various vulnerability areas in the structural system that require specific consideration. The Evaluation Statements are written so that a positive or 'true' response to a statement implies that the building is adequate in that area. If a building passes all applicable statements with 'true' responses, it can be passed without further evaluation, i.e., it is deemed not to be a life-safety hazard. For statements that are 'false,' additional evaluation is required. A 'false' statement does not necessarily imply that a complete structural evaluation is necessary, or that the building is automatically deficient; it simply flags an area of concern for the evaluating engineer and implies that a life-safety hazard may exist. If any such potential life-safety hazards are identified, an appropriate detailed analysis is recommended, with acceptance criteria suggested for each element of concern. Through this procedure, not iv only are weak links in the structural system identified, but the presence of the life-safety hazard is also assessed. These Guidelines provide a methodology that can be applied nation-wide to all existing buildings that are suspected of posing a potentially serious risk of loss of life and injury in case of a damaging earthquake. This procedure covers both structural and nonstructural elements and requires the review of construction documents, the general condition of the building, and calculations. The Guidelines include checklists, diagrams, and sketches that help to guide the user. These Guidelines are organized to be compatible with the NEHRP Handbook of Techniques for Seismically Rehabilitating Existing Buildings (FEMA, 1992-2). The NEHRP document identifies and describes seismic rehabilitation techniques for a broad spectrum of building types and building components, including both structural and non-structural elements. To aid the reader in the process of moving from evaluation to rehabilitation, the Guidelines and the NEHRP document on upgrading techniques are both organized to address building systems and components. Building components are organized into the following subsystems: vertical elements resisting horizontal loads (i.e., moment resisting frames, shear walls, and braced frames); horizontal elements resisting lateral loads (i.e., diaphragms); foundations; connections between subsystems; and non-structural building components. The NEHRP document has, however, not been adapted to be compatible with Canadian practice. The Guidelines provide the tools to identify seismically hazardous buildings. It is not a directive or a requirement, but rather a practical technical approach that can be used to identify seismic deficiencies in existing buildings.

NRCC Guideline for Seismic Upgrading of Building Structures
Author: D.E. Allen et al | Size: 2.3 MB | Format:PDF | Quality:Original preprint | Publisher: NRCC | Year: Dec. 1995 | pages: 54 | ISBN: ISBN 0-660-16262-8
This Guideline provides information and advice on the seismic upgrading of existing building structures, and is intended for use by qualified structural engineers. It is a companion document to the recently published Guidelines for Seismic Evaluation of Existing Buildings l and the Manualfor Screening of Buildings for Seismic Investigation,2 both of which are related to the National Building Code of Canada. 3 The Guideline describes conventional techniques of seismic upgrading of building structures and discusses their relative merits based on the objectives of seismic upgrading and the principal considerations in their choice and design. It also describes innovative seismic upgrading techniques such as supplementary damping and contains references to more detailed information on such techniques. It does not include techniques for upgrading of non-structural building components

This guide presents simplified methods and design techniques that facilitate and speed the engineering of low-rise buildings within certain limitations. Material is presented in an order that follows typical design process with procedures introduced as the designer will need them in the course of a building design.

The New Structuralism announces a new order in design and construction. With the onset of digital technologies, existing parameters have shifted. The old order of standardised design and its established processes no longer hold sway; contemporary architectural design can now be characterised by irregularity, and an appetite for producing customised non-standard, complex, curvilinear forms. The shift in design and production technologies requires a seamless design approach that fully acknowledges the interdependence of design and fabrication.
In this issue of 2, Rivka Oxman and Robert Oxman are eloquently calling for a new model of architectural production in which architects and engineers work together in a higher level of collaboration. The structural engineer is no longer the fi xer brought in during the late design stage to make a design work, but integral to the earliest generative stages. Design is no longer wholly dictated by form with structure following behind; structure becomes integral to form-fi nding.

Author: Roy R. Craig, Jr.-Andrew J. Kurdila | Size: 241 MB | Format:PDF | Quality:Scanner | Publisher: Wiley | Year: 2006 | pages: 745 | ISBN: 9780471430445-0471430447
From theory and fundamentals to the latest advances in computational and experimental modal analysis, this is the definitive, updated reference on structural dynamics.
This edition updates Professor Craig's classic introduction to structural dynamics, which has been an invaluable resource for practicing engineers and a textbook for undergraduate and graduate courses in vibrations and/or structural dynamics. Along with comprehensive coverage of structural dynamics fundamentals, finite-element-based computational methods, and dynamic testing methods, this Second Edition includes new and expanded coverage of computational methods, as well as introductions to more advanced topics, including experimental modal analysis and "active structures." With a systematic approach, it presents solution techniques that apply to various engineering disciplines. It discusses single degree-of-freedom (SDOF) systems, multiple degrees-of-freedom (MDOF) systems, and continuous systems in depth; and includes numeric evaluation of modes and frequency of MDOF systems; direct integration methods for dynamic response of SDOF systems and MDOF systems; and component mode synthesis.
Numerous illustrative examples help engineers apply the techniques and methods to challenges they face in the real world. MATLAB® is extensively used throughout the book, and many of the .m-files are made available on the book's Web site. Fundamentals of Structural Dynamics, Second Edition is an indispensable reference and "refresher course" for engineering professionals; and a textbook for seniors or graduate students in mechanical engineering, civil engineering, engineering mechanics, or aerospace engineering.
