Sustainable Steel and Timber Constructions
Master course at Czech Technical University in Prague /
C12 Timber structures
1. week Introduction to advanced timber structures
History of building construction (timber framed houses, roof and wall structures, bridges), wood as a structural material (technical and non-technical characteristics), potential of timber in building sector.
2. week Wood properties
Structure of wood (macro-, micro-, submicro-), natural features in sawn timber, shrinkage, creep, loss of strength, evaluation of structural properties.
3. week Structural timber and glulam
Grading, mechanical properties, poles and round timber, solid timber, structural timber with special properties (KVH, DUO/TRIO). Glulam production and properties, structural use of glulam.
4. week Wood based panels
Panels based on wood pieces (fibres, strands and veneers) and also wood boards. Detailed description of cross laminated timber - production, load- carrying behaviour, modelling and verification ( plates, walls and joints).
5. week Limit states design – structural members
Reliability assessment (deterministic, semi or fully probabilistic). Design of members according to Eurocode 5 (stress in one direction, combined stresses, with varying cross-section or curved shape). Stability of members.
6. week Limit states design – connections
Connections with metal fasteners (nails, dowels, bolts, screws, connectors, punched metal plate fasteners). Design according to Eurocode 5.
7. week Limit states design – components, assemblies and composite structures
Glued thin-webbed or thin-flanged beams, roof and floor diaphragms, timber-concrete composite floors, strengthening of timber members.
8. week Planar and spatial timber structures
Beams, portal frames, arches, trusses, bracing, serviceability limit state criteria, 2nd order theory. Space grid and shell structures.
9. week Timber frame houses
Methods of construction, design models, connections between elements.
10. week Timber bridges
Types and sizes, structural systems, bridge decks, connections and details, dynamic effects, maintenance. Design according to Eurocode 5.
11. week Fire resistance of timber structures
Behaviour of timber and wood-based materials in fire. Fire resistance of timber members and joints. Design according to Eurocode 5.
12. week Durability of timber structures
Natural durability of timber, deterioration mechanisms, hazard and durability classes, Timber structures in aggressive environments.
13. week Reserve
Seminars:
· Design of column and beam of a heavy timber frame structure.
· Design of moment resisting connection.
· Design of beam reinforced by glued-in rods.
· Design of timber-concrete composite floor of a multi-storey building.
