2. 1. Medieval Timber Roof Structures: Conceptual methods for investigation and evaluation of structural behaviour, with the horizontal thrust problem as an application

   Author : Carl Thelin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conservation; thrust; medieval churches; preservation; structural behaviour; base of the roof; roof truss; roof structure; horizontal support; FEM;

   Abstract : The medieval timber roof structures hidden in the attics of many Swedish churches represent the advanced building technology of the time. They are an important cultural heritage, their being bearers of information from a period regarding which other direct sources of information are scarce. READ MORE

4. 2. Probabilistic System Effects in Timber Structures

   Author : Martin Hansson; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

   Abstract : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. READ MORE

5. 3. Probabilistic Analysis and Reliability of Engineering Structures

   Author : Anders Olsson; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; roof truss; racking system; importance sampling; Latin hypercube sampling; reliability;

   Abstract : This thesis, consisting of six papers, concerns methods for probabilistic analysis of engineering structures. The work comprises evaluations of available methods, developments of new and improved methods, and applications of probabilistic analysis to engineering structures. READ MORE

6. 4. The human factor in structural engineering: A source of uncertainty and reduced structural safety

   Author : Martin Fröderberg; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural engineering Uncertainty Human error;

   Abstract : It is known that human errors are the cause of most structural failures. Extreme loads or material deficiencies are normally of secondary importance. This Project has studied the human factor in the design phase; how subjective decisions, individual knowledge and the use of advance tools and codes affect structural safety and structural design.
