Wind Loading of Structures, Third Edition
Holmes Structural Engineering “A fine text for a wind engineering course… A must for any wind engineer’s library. –Leighton Cochran, consulting engineer “The first book I recommend to the many customers I have who—as practicing structural engineers Wind not wind engineers—are in need of a comprehensive yet understandable reference text.” –Daryl Boggs, CPP, Inc Wind Loading of Structures “I highly recommend this book by Dr John Holmes for use in graduate and senior undergraduate studies, structural engineering design against wind actions, and other professional design Loading of practices.” –Kenny Kwok, University of Western Sydney Wind forces from various types of extreme wind events continue to generate ever-increasing damage to buildings and other structures. The third edition of this well-established book fills an Structures important gap as an information source for practising and academic engineers alike, explaining the principles of wind loads on structures, including the relevant aspects of meteorology, bluff- body aerodynamics, probability and statistics, and structural dynamics. Among the unique features of the book are its broad view of the major international codes and Third Edition standards, and information on the extreme wind climates of a large number of countries of the world. It is directed towards practising (particularly structural) engineers, and academics and graduate students. The main changes from the earlier editions are: • Discussion of potential global warming effects on extreme events • More discussion of tornados -
On Dimensionless Numbers
chemical engineering research and design 8 6 (2008) 835–868 Contents lists available at ScienceDirect Chemical Engineering Research and Design journal homepage: www.elsevier.com/locate/cherd Review On dimensionless numbers M.C. Ruzicka ∗ Department of Multiphase Reactors, Institute of Chemical Process Fundamentals, Czech Academy of Sciences, Rozvojova 135, 16502 Prague, Czech Republic This contribution is dedicated to Kamil Admiral´ Wichterle, a professor of chemical engineering, who admitted to feel a bit lost in the jungle of the dimensionless numbers, in our seminar at “Za Plıhalovic´ ohradou” abstract The goal is to provide a little review on dimensionless numbers, commonly encountered in chemical engineering. Both their sources are considered: dimensional analysis and scaling of governing equations with boundary con- ditions. The numbers produced by scaling of equation are presented for transport of momentum, heat and mass. Momentum transport is considered in both single-phase and multi-phase flows. The numbers obtained are assigned the physical meaning, and their mutual relations are highlighted. Certain drawbacks of building correlations based on dimensionless numbers are pointed out. © 2008 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Fluid-Structure Interaction in Bluff-Body Aerodynamics and Long-Span Bridge Design: Phenomena and Methods
Fluid-Structure Interaction in Bluff-Body Aerodynamics and Long-Span Bridge Design: Phenomena and Methods G. Morgenthal CUED/D-STRUCT/TR.187 University of Cambridge Department of Engineering Technical Report No. CUED/D-Struct/TR.187 Fluid-Structure Interaction in Bluff-Body Aerodynamics and Long-Span Bridge Design: Phenomena and Methods by Guido Morgenthal Magdalene College August 2000 Introduction Page 3 ABSTRACT The interaction between a fluid flow and an embedded elastic bluff body is extremely complex. Different response modes and flow phenomena exist depending on the flow characteristics, the body geometry and the structural properties like stiffness and damping. This poses a particular challenge to the development of analytical and numerical models and renders experimental methods still the most reliable tool. This report aims at introducing the various phenomena and at reviewing the most important analytical and numerical methods of analysis. It is largely based on a literature survey which has been carried out in preparation for a PhD degree on numerical methods for fluid-structure interaction analysis in long-span bridge design at the University of Cambridge.

Module 6 : Lecture 1 DIMENSIONAL ANALYSIS (Part – I) Overview
NPTEL – Mechanical – Principle of Fluid Dynamics Module 6 : Lecture 1 DIMENSIONAL ANALYSIS (Part – I) Overview Many practical flow problems of different nature can be solved by using equations and analytical procedures, as discussed in the previous modules. However, solutions of some real flow problems depend heavily on experimental data and the refinements in the analysis are made, based on the measurements. Sometimes, the experimental work in the laboratory is not only time-consuming, but also expensive. So, the dimensional analysis is an important tool that helps in correlating analytical results with experimental data for such unknown flow problems. Also, some dimensionless parameters and scaling laws can be framed in order to predict the prototype behavior from the measurements on the model. The important terms used in this module may be defined as below; Dimensional Analysis: The systematic procedure of identifying the variables in a physical phenomena and correlating them to form a set of dimensionless group is known as dimensional analysis. Dimensional Homogeneity: If an equation truly expresses a proper relationship among variables in a physical process, then it will be dimensionally homogeneous. The equations are correct for any system of units and consequently each group of terms in the equation must have the same dimensional representation. This is also known as the law of dimensional homogeneity. Dimensional variables: These are the quantities, which actually vary during a given case and can be plotted against each other. Dimensional constants: These are normally held constant during a given run. But, they may vary from case to case. Pure constants: They have no dimensions, but, while performing the mathematical manipulation, they can arise. -
