Basic Principles of Steel Structures Design

普通高等教育“十四五”规划教材

本书根据《钢结构设计标准》(GB 50017—2017）和《门式刚架轻型房屋钢结构技术规范》（GB 51022—2015）等几本钢结构相关的规范进行编写。本书通过讲述平台钢结构、轻型门式刚架、重型工业厂房（包括角钢屋架和吊车梁）、大跨屋盖结构、多高层建筑结构、钢管结构这几类工程中常用房屋建筑钢结构的设计方法，介绍了与钢结构相关的常用中国规范的基本设计条文和原则。本书最大程度地让留学生和双语教育的中国学生了解并掌握中国钢结构设计的一般要求和基本方法。

This book consists of 9 Chapters. The content of Chapter 1 includes the introduction,characteristics,application scope,development and classification of steel structures. Chapter 2 discusses material properties of steel structures,including mechanical properties of structural steel and its influencing factors,and the types and choices of steel and section steel. In Chapter 3,several possible failure modes of steel structures and their characteristics are illustrated. Chapter 4 introduces the basic methods of the steel structures design. Chapter 5 introduces connection types of steel structures,focusing on the calculation and construction requirements of welded connections and bolted connections. Chapter 6 introduces the behavior of the axially loaded component,describing the section strength,stiffness,overall stability and local stability calculation. Additionally,the design method of the axially loaded component is also illustrated in Chapter 6. Chapter 7 introduces the behavior of flexural member,focusing on section strength,stiffness,overall stability calculation,local stability design and stiffener design. Chapter 8 introduces the behavior of compression-flexural and tension-flexural members,focusing on section strength and stiffness calculation. The overall stability and local stability calculation of compression-flexural members are also illustrated. Chapter 9 briefly introduces the seismic performance of steel members and steel structure joints.
