【簡介】 Provides structural engineers with the knowledge and practical tools needed to perform structural designs for wind that incorporate major technological, conceptual, analytical and computational advances achieved in the last two decades.With clear explanations and documentation of the concepts, methods, algorithms, and software available for accounting for wind loads in structural design, it also describes the wind engineer's contributions in sufficient detail that they can be effectively scrutinized by the structural engineer in charge of the design.Wind Effects on Structures: Modern Structural Design for Wind, 4th Edition is organized in four sections. The first covers atmospheric flows, extreme wind speeds, and bluff body aerodynamics. The second examines the design of buildings, and includes chapters on aerodynamic loads; dynamic and effective wind-induced loads; wind effects with specified MRIs; low-rise buildings; tall buildings; and more. The third part is devoted to aeroelastic effects, and covers both fundamentals and applications. The last part considers other structures and special topics such as trussed frameworks; offshore structures; and tornado effects.Offering readers the knowledge and practical tools needed to develop structural designs for wind loadings, this book: Points out significant limitations in the design of buildings based on such techniques as the high-frequency force balanceDiscusses powerful algorithms, tools, and software needed for the effective design for wind, and provides numerous examples of application Discusses techniques applicable to structures other than buildings, including stacks and suspended-span bridges Features several appendices on Elements of Probability and Statistics; Peaks-over-Threshold Poisson-Process Procedure for Estimating Peaks; estimates of the WTC Towers' Response to Wind and their shortcomings; and moreWind Effects on Structures: Modern Structural Design for Wind, 4th Edition is an excellent text for structural engineers, wind engineers, and structural engineering students and faculty.

內容簡介 Theory and Design for Mechanical Measurements provides a well-founded, fundamental background in the theory and practice of engineering measurements. Designed to align with a variety of undergraduate course structures, the book offers a rigorous treatment of the subject with a flexible pedagogical framework for use in graduate studies, independent study, or professional reference. It integrates the necessary elements to conduct engineering measurements through the design of measurement systems and measurement test plans, with an emphasis on the role of statistics and uncertainty analyses in that process. This International Adaptation offers new or expanded material on several topics, mostly under Fundamentals of Measurement, Systematic and Random Errors and Standard Uncertainties, Sensors and Actuators. Along with extensive coverage of device selection, test procedures, measurement system performance, the book includes practical discussion on real-world methods and techniques. The current applications of measurement theory and design are presented with examples, case studies, and vignettes. The updated end-of-chapter material includes significant number of new problems. 產品目錄 TABLE OF CONTENTS 1 FUNDAMENTAL OF MEASUREMENTS 1.1 Introduction 1.2 General Measurement System 1.3 Experimental Test Plan 1.4 Calibration 1.5 Standards 1.6 Presenting Data 1.7 Loading Effects 1.8 Applications of Measurement Systems Summary Nomenclature References Problems 2 STATIC AND DYNAMIC CHARACTERISTICS OF SIGNALS 2.1 Introduction 2.2 Input/Output Signal Concepts 2.3 Signal Analysis 2.4 Signal Amplitude and Frequency 2.5 Fourier Transform and the Frequency Spectrum Summary References Suggested Reading Nomenclature, Problems 3 MEASUREMENT SYSTEM BEHAVIOR 3.1 Introduction, 3.2 General Model for a Measurement System 3.3 Special Cases of the General System Model 3.4 Transfer Functions 3.5 Phase Linearity 3.6 Multiple-Function Inputs 3.7 Coupled Systems Summary References Nomenclature Subscripts Problems 4 PROBABILITY AND STATISTICS 4.1 Introduction 4.2 Statistical Measurement Theory 4.3 Describing the Behavior of a Population 4.4 Statistics of Finite-Sized Data Sets 4.5 Hypothesis Testing 4.6 Chi-Squared Distribution 4.7 Regression Analysis 4.8 Data Outlier Detection 4.9 Number of Measurements Required 4.10 Monte Carlo Simulations 4.11.
