Steel frames are used in many commercial high-rise buildings, as
well as industrial structures, such as ore mines and oilrigs.
Enabling construction of ever lighter and safer structures, steel
frames have become an important topic for engineers.
This book, split into two parts covering advanced analysis and
advanced design of steel frames, guides the reader from a broad
array of frame elements through to advanced design methods such as
deterministic, reliability, and system reliability design
approaches. This book connects reliability evaluation of structural
systems to advanced analysis of steel frames, and ensures that the
steel frame design described is founded on system reliability.
Important features of the this book include:
* fundamental equations governing the elastic and elasto-plastic
equilibrium of beam, sheer-beam, column, joint-panel, and brace
elements for steel frames;
* analysis of elastic buckling, elasto-plastic capacity and
earthquake-excited behaviour of steel frames;
* background knowledge of more precise analysis and safer design
of steel frames against gravity and wind, as well as key
discussions on seismic analysis.
* theoretical treatments, followed by numerous examples and
applications;
* a review of the evolution of structural design approaches, and
reliability-based advanced analysis, followed by the methods and
procedures for how to establish practical design formula.
Advanced Design and Analysis of Steel Frames provides students,
researchers, and engineers with an integrated examination of this
core civil and structural engineering topic. The logical treatment
of both advanced analysis followed by advanced design makes this an
invaluable reference tool, comprising of reviews, methods,
procedures, examples, and applications of steel frames in one
complete volume.
Autorentext
Professor Li received his PhD in Structural Engineering at Tongji University in 1988. That same year he started working at the University as a lecturer in Structural Engineering, and over the next six years he worked his way up to Associate Professor, and then Professor in 1994. His research interests lie mainly in the behavior and design of multi-storey steel buildings, the fire-resistance of steel structures and the dynamic identification of structures. He is an active member on the Editorial board of five International journals covering areas of research in steel and composite structures, structural engineering and materials, computational structural engineering, and advanced steel construction. He is the author of four books in Chinese, and over eighty research papers.
