After successful completion of the course, students are able to

• Identify wood mechanics
• chose and apply wood based products and composites depending on the demand of the project
• structurally model and verify linear structural elements both manually and with software support according to EC5 for ultimate load, serviceability load and fire
• include aspects of machining, assembly and durability in the process of the design

The lecture comprises the following topics:

• basics in wood mechanics
• fundamentals of mechancis of market-relevenat wood products (1D, 2D)
• connection-systems: introduction, characteristics, mechanical behavior
• construction elements and systems: introduction, characteristics, mechanical behavior
• structural design and dimensioning according to the current standards with the focus of completeness (servicability limit, ultimate limit, fire)
• Introduction to numerical simulation tools (commercial structural analysis software) for the design of timber structures
• special topics (durability, errection and assembling)

During the exercises part, 6 individual examples regarding modeling and design strategies of timber elements and structures are discussed. To each of these 6 topics an input presentation (mandatory) will be given. Based on these presentations home exercises related to these topics have to be worked out in groups of three students.

For home exercises the commercial structural analysis software RFEM and RX-Holz (Dlubal Software Company) is used. A student version (free of charge) and further information can be found at the following link:

For personal respective practical training, after an introductory lecture six pieces of homework with issues from the theoretical course have to be realized in collaboration with other students

Die folgenden Änderungen gelten ab 21.1.2020 für die Holzbau 1 VU:

• Die mündliche Prüfung ist nicht mehr an den positiven Abschluss des Übungsteils geknüpft. Studierende können damit bereits vor Bekanntgabe der Ergebnisse der Übung sicher sein, dass sie zur Prüfung antreten können. Da die Einstiegsfrage weiterhin Teil der mündlichen Prüfung ist, empfehlen wir allerdings vor dem Antritt die Übung zu absolvieren.
• Bei der mündlichen Prüfung wird nur mehr der aktuelle, reduzierte Fragenkatalog geprüft. Die Einstiegsfrage bleibt an das Semester gebunden in dem die Übung absolviert wurde, da sie dem Zweck der Kontrolle dient ob die Übung selbst gemacht wurde.
• Bei der Übung werden weiterhin nur mehr 4 Beispiele behandelt.

Oral exam with one question to the homework as entry to the oral exam and two questions from the list of questions

recommended prior knowledge:

Baustofflehre + Mechanik + Festigkeitslehre + Baustatik+ Tragwerke-Baukonstruktionen
