Concrete-filled stainless steel tubular (CFSST) columns are
increasingly used in modern composite construction due to their
high strength, high ductility, high corrosion resistance, high
durability and aesthetics and ease of maintenance. Thin-walled
CFSST columns are characterized by the different strain-hardening
behavior of stainless steel in tension and in compression, local
buckling of stainless steel tubes and concrete confinement. Design
codes and numerical models often overestimate or underestimate the
ultimate strengths of CFSST columns. This book presents accurate
and efficient computational models for the nonlinear inelastic
analysis and design of CFSST short and slender columns under axial
load and biaxial bending. The effects of different strain-hardening
characteristics of stainless steel in tension and in compression,
progressive local and post-local buckling of stainless steel tubes
and concrete confinement are taken into account in the
computational models. The numerical models simulate the axial
load-strain behavior, moment-curvature curves, axial
load-deflection responses and axial load-moment strength
interaction diagrams of CFSST columns. The book describes the
mathematical formulations, computational procedures and model
verifications for circular and rectangular CFSST short and slender
columns. The behavior of CFSST columns under various loading
conditions is demonstrated by numerous numerical examples. This
book is written for practising structural and civil engineers,
academic researchers and graduate students in civil engineering who
are interested in the latest computational techniques and design
methods for CFSST columns.
Performance-Based Optimization of Structures introduces a method to
bridge the gap between structural optimization theory and its
practical application to structural engineering. The
Performance-Based Optimization (PBO) method combines modern
structural optimisation theory with performance based design
concepts to produce a powerful technique for use in structural
design. This book provides the latest PBO techniques for achieving
optimal topologies and shapes of continuum structures with stress,
displacement and mean compliance constraints. The emphasis is
strongly placed on practical applications of automated PBO
techniques to the strut-and-tie modelling of structural concrete,
which includes reinforced and prestressed concrete structures.
Basic concepts underlying the development of strut-and-lie models,
design optimization procedure, and detailing of structural concrete
are described in detail. Alternative approaches to topology
optimization are also introduced. The book contains numerous
practical design examples illustrating the nature of the load
transfer mechanism of structures.

Steel and composite steel-concrete structures are widely used in
modern bridges, buildings, sport stadia, towers, and offshore
structures. Analysis and Design of Steel and Composite Structures
offers a comprehensive introduction to the analysis and design of
both steel and composite structures. It describes the fundamental
behavior of steel and composite members and structures, as well as
the current design criteria and procedures given in Australian
standards AS/NZS 1170, AS 4100, AS 2327.1, Eurocode 4, and
AISC-LRFD specifications. Featuring numerous step-by-step examples
that clearly illustrate the detailed analysis and design of steel
and composite members and connections, this practical and
easy-to-understand text: Covers plates, members, connections,
beams, frames, slabs, columns, and beam-columns Considers bending,
axial load, compression, tension, and design for strength and
serviceability Incorporates the author's latest research on
composite members Analysis and Design of Steel and Composite
Structures is an essential course textbook on steel and composite
structures for undergraduate and graduate students of structural
and civil engineering, and an indispensable resource for practising
structural and civil engineers and academic researchers. It
provides a sound understanding of the behavior of structural
members and systems.
