SCI P286 Guide to Evaluating Design Wind Loading to BS6399-2
Size: 1.30 MB | Format:PDF | Quality:Unspecified | Publisher: The Steel Construction Institute | Year: 1997 | pages: 99 | ISBN: 1859421342
This publication presents guidance on the use of the design procedures given in BS 6399-2:1997, Loading for buildings. Code of practice for wind loads, to calculate the wind loads on buildings, using methods that are suitable for hand calculations. These procedures include the Standard Method and Hybrid Method, which are presented in the Code. Two new design methods are introduced in this publication, called the Simplified Standard Method and the Simplified Hybrid Method.
As the names suggest these methods are simplified versions of the methods given in the Code. The purpose of
introducing the additional methods is to present a ‘back-of-the-envelope’ method (the Simplified Standard Method) and a method that is considered to be a suitable balance
between calculation effort and economical design (the Simplified Hybrid Method).
The publication presents a concise step-by-step procedure for all the design methods that are suitable for hand calculation. Detailed explanation is provided for each calculation step. Guidance is also presented on the use of pressure coefficients, and the treatment of dominant openings, overall loads and asymmetric loads. The guidance aims to produce economical design while ensuring the design effort is kept to a minimum. Design examples are presented to show the use of the Standard, Simplified Standard and
Simplified Hybrid methods.
Throughout this publication, constant reference is made to the clauses and figures in the Code. This publication is not intended to be a ‘stand-alone document’ and designers will
need to use it alongside the Code, BS 6399-2:1997.

Shell structures are widely used in the fields of civil, mechanical, architectural, aeronautical, and marine engineering. Shell technology has been enhanced by the development of new materials and prefabrication schemes. Despite the mechanical advantages and aesthetic value offered by shell structures, many engineers and architects are relatively unacquinted with shell behaviour and design.
This book familiarizes the engineering and architectural student, as well as the practicing engineer and architect, with the behaviour and design aspects of shell structures. Three aspects are presented: the Physical behaviour, the structural analysis, and the design of shells in a simple, integrated, and yet concise fashion. Thus, the book contains three major aspects of shell engineering: (1) physical understanding of shell behaviour; (2) use of applied shell theories; and (3) development of design methodologies together with shell design examples.
The theoretical tools required for rational analysis of shells are kept at a modest level to give a sound grasp of the fundamentals of shell behaviour and, at the same time, an understanding of the related theory, allowing it to be applied to actual design problems. To achieve a physical understanding of complex shell behaviour, quantitative presentations are supplemented by qualitative discussions so that the reader can grasp the `physical feeling' of shell behaviour. A number of analysis and detailed design examples are also worked out in various chapters, making the book a useful reference manual.

Calculus for Scientists and Engineers: Early Transcendentals
Author: William L. Briggs, Lyle Cochran, Bernard Gillett, Eric Schulz | Size: 31 MB | Format:PDF | Quality:Original preprint | Publisher: Pearson | Year: 2012 | Pages: 1344 | ISBN: 9780321785374
Drawing on their decades of teaching experience, William Briggs and Lyle Cochran have created a calculus text that carries the teacher’s voice beyond the classroom. That voice—evident in the narrative, the figures, and the questions interspersed in the narrative—is a master teacher leading readers to deeper levels of understanding. The authors appeal to readers’ geometric intuition to introduce fundamental concepts and lay the foundation for the more rigorous development that follows. Comprehensive exercise sets have received praise for their creativity, quality, and scope. This book is an expanded version of Calculus: Early Transcendentals by the same authors, with an entire chapter devoted to differential equations, additional sections on other topics, and additional exercises in most sections.

Author: Michael Joseph French | Size: 19 MB | Format:PDF | Quality:Scanner | Publisher: Springer | Year: 1999 | Pages: 252 | ISBN: 9781447136279
Although first published nearly thirty years ago, this book remains up-to-date, intellectually stimulating and realistic. Unlike most texts in the field, it relates design closely to the science and mathematics that are students' chief concern, and shows their relevance. It shows how to make simple but illuminating calculations, and how to achieve the insight and the invention that often result from them. Covering design principles in depth, this is, and remains, an original book: although some of the ideas which were novel in 1971 are now widely accepted, others remain new.

Liebing is a proven expert and author of specialized literature. He is also a professor in the field of planning rendering and detailing and this is his somewhat different version of a handbook.
The well-known book, "Architectural Detailing", by Professor E. Allen und P. Rand, introduces detail as a choice of system and construction. It covers a major field of instruction that Liebing expands with an important practical aspect.
The "Handbook of Detailing" is about the mechanics , the function of the drafted details. Not the exemplary rendering of details but the best rendering for the respective purpose whether at the construction site or the office. The author zeros in on frequent weaknesses in detailing and shows positive examples. He consciously does without rendering copies and offers an "Anatomy of Planning Rendering" that can be adjusted to create the optimal effect.

This book argues that the issues surrounding sustainable transport constitute a new - post-modern - phase in transport policy and management. Achieving sustainable transport requires more than 'optimal' management of congestion and the effects on public health and the environment. Assessments of external effects, and their optimal levels, tend to be piecemeal, localized, and focused on a specific type of effect. Sustainability, on the other hand, is a comprehensive, forward-looking concept that encompasses the achievement of a state of society that is better overall; it requires a widened concept of welfare that includes environmental quality and social justice in both the short and long term. This book is organized into three sections, each discussing a major set of challenges to the transition to a sustainable transport system.

Prepared by the Task Committee on Urban Aerodynamics of the Environmental Wind Engineering Committee of the Technical Council on Wind Engineering of ASCE. Urban Aerodynamics: Wind Engineering for Urban Planners and Designers introduces the basic tools and technology used by engineers to determine the effects of wind on city streets and structures. Familiarity with the fundamentals of urban aerodynamics offers many advantages to city planners and urban designers, most especially the opportunity to incorporate quantitative techniques into the design and development process. This volume traces the historical development of wind engineering techniques leading up to today's use of boundary layer wind tunnel studies and computational fluid dynamics assessments. Examples show the application of wind engineering to address urban issues such as pedestrian-level wind control, design for hurricane shelter, urban summer breeze penetration, winter wind shielding, the natural ventilation of buildings, and dispersion of airborne pollutants. Current tools and techniques for both qualitative and quantitative assessment of urban wind effects are reviewed, and an extensive list of references is included. This book is a compact essential reference for city planners, urban designers, and architects, as well as structural and wind engineers.

Wind Issues in the Design of Buildings explains the ways that structural designers accommodate the impact of extreme wind events on the built environment. By studying the flow and pressure fields around buildings, architects and engineers can identify and select the best strategies for ensuring that a building will resist the loads due to high winds, maintaining pleasant conditions in outdoor spaces, assessing natural ventilation potential, and seeing that any exhaust fumes are dispersed adequately. This volume identifies wind characteristics and describes the effects of winds generated by hurricanes, tornadoes, and thunderstorms. It explains the internal and external pressures on a building's cladding (skin) and the effects of wind-borne debris. A building's response to the structural loads caused by wind is outlined, along with techniques for resisting wind. A chapter is devoted to wind tunnels and physical modeling to predict structural loads, cladding response, pedestrian experience, topographic effects, and snow deposition. A section of frequently asked questions, a glossary, and recommended reading make this material in this volume accessible to students and nontechnical members of project teams. Structural engineers and architects will find this book a useful aide in explaining wind-related issues to clients, builders, building officials, and owners. Students in structural and architectural engineering will welcome the clear, concise presentation of an important component of structural design.
