5 Study process : 1. Lectures, - Theory and - Examples. 1. Execises. 2. Homeworks. 3. Laboratory demonstrations. 4. Excursions. Multi-storey office buildings Commercial buildings Rowhouses Agriculture buildings Not in focus Not in focus Small apartment houses Multi-storey apartment houses Main focus Industrial buildings Sport halls

6 Learning Outcomes : Understands how the structure of wood reflects in its structural properties. Knows the wood-based structural products and how to use them in structural systems. Comprehends the design principles of large timber buildings and their structural components. Understands the design principles of joints in wood structures. Understands the value of architectural and building physical design of wooden buildings. Understands the fire-safety of timber structures.

7 Goal for everybody autumn , Analysis of structural system (prof Jari Puttonen) : 1. Drafting and design. P A R T S Loads Load bearing structures Joints and connections Stability 2. Modelling. 3. Analysing. 4. Design of joints.

8 Lectures, period I Friday : Introduction : Goal, content, studies. Special features of wood and timber structures. Advanced wood structures Sawn timber and GL timber : Structural systems. Curved structures, arches. Notches and holes. Connections. Specially in large halls. Composite structures Prof. Pekka Heikkinen ; Wood and architecture : - History. Respect. Inspiration. - Components, connections, industrial solutions. - Rules, control, architecture Plywood, LVL, CLT : Plates. Stabilizing plate structures Sandwich structures. Connections. Specially in multi-storey houses.

9 Lectures continues Space Trusses and Beam Shells : Modelling, analysis. Beam shells and plate shells. Folded structures. New cases ; Shanghai and Halti Mechanical joints : - Dowel theory by Johansen.
