1. 1. Structural Analysis Methods for the Assessment of Reinforced Concrete Slabs

   Författare :Jiangpeng Shu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge Deck; Finite Element FE Analysis; Shear and Punching; Structural Response; Reinforced Concrete Slabs; Multi-level Assessment Strategy;

   Sammanfattning : Reinforced concrete (RC) slabs are among the most critical parts of the load-carrying capacity of such structures as bridges and parking decks. Previous research indicated that the assessment methods used in current practices largely underestimated the load-carrying capacity. LÄS MER

3. 2. Concrete Bridges : Improved Load Capacity

   Författare :Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. LÄS MER

4. 3. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

   Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

   Sammanfattning : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.

7. 5. Control of Cracking due to Imposed Strains in Concrete Structures

   Författare :Dan Pettersson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulic engineering; Civil engineering; Friction.; Restraint; Shrinkage; Imposed deformations; Minimum reinforcement; Crack widths; Reinforced concrete; Crack development; Crack control; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : This thesis is concerned with crack control due to imposed deformations in concrete structures. The objective of crack control may either be to prevent cracking or to limit the crack widths. The aim here is to increase the knowledge in both fields for some common structures. Five papers are included and the three last concern crack development. LÄS MER
