STRUCTURAL
MECHANICS
Modelling and Analysis
of Frames and Trusses
Karl-Gunnar Olsson, Chalmers University of Technology, Sweden
Ola Dahlblom, Lund University; Sweden
This textbook in structural mechanics is based on the methodology of the finite element method. The
understanding of basic elements of structural mechanics - springs, bars, beams and foundations
- is gradually built up in one, two and three dimensions. Using these elements, it is demonstrated
how complex load-bearing structures can be modelled and analysed. Methods for linear as well as
geometric and material non-linear analyses are presented. In order to highlight the generality of
the described methodology, a short section that addresses other areas of applied mechanics such as
thermal conduction, moisture diffusion and groundwater flow is included.
Three key learning objectives are supported: (1) knowledge of the basic theory of structural mechanics;
(2) skills in modelling and analysis of structures and (3) ability to evaluate and improve the efficiency
of proposed structural configurations in a design process.
Key features:
• Deals with modelling and analysis of trusses and frames using a systematic matrix formulated
displacement method with the language and flexibility of the finite element method
• Element matrices are established from analytical solutions to the differential equations
• Provides a strong toolbox with elements and algorithms for computational modelling and numerical
exploration of truss and frame structures
• Discusses the concept of stiffness as a qualitative tool to explain structural behaviour
• Includes numerous exercises, for some of which the computer software CALFEM is used. In order
to support the learning process, CALFEM gives the user full overview of the matrices and algorithms
used in a finite element analysis
Structural Mechanics: Modelling and Analysis of Frames and Trusses is an ideal textbook for
undergraduate students. Computer programs that support the book can be downloaded for free at
www.structarch.org.
