MABY4400 Structural Analysis and Design Emneplan

The course gives the students the necessary fundamental understanding of the principles used in the design of large complex structures. An important goal of the course is to give the students knowledge and experience of how to use the finite element method (FEM) correctly in design calculations, with emphasis on non-linearities in structural engineering. In particular, the course will give the students a deeper understanding of the non-linear behaviour of structural materials, where the students will gain both theoretical and practical insight. Other important topics addressed are dynamic wind and earthquake loads, and the background for modern standards and how uncertainties in load and material calculations are taken into account in the design process.

New exam spring 2020:

The project assignement (A and B) will be individual, i.e. (not in group of 2-3)

The oral exam is cancelled and the individual project assignment will be the only assessment (exam).

The exam can be appealed.

[Originally

Type of assessment:

1) Individual oral exam, weighted 60 %

2) Project report, prepared by groups of 2-3 students, approx. 20-30 pages, including a presentation - weighted 40 %.

All assessment parts must be awarded a pass grade (E or better) in order for the student to pass the course. Students must be awarded an E or better on their project report to be allowed to take the oral exam. Individual questions about the project report will be also be asked in connection with the presentation of the report. In the event of a resit or rescheduled exam, oral examination may be used instead. If oral exams are used for resit and rescheduled exams, the result cannot be appealed.

Assessment part : 1) and 2) cannot be appealed.

The teaching consists of lectures, exercises (written assignments or computer-based assignments) and project work. The exercises are linked to the topics taught. The project assignment is to be carried out in groups of 1-3 students and concerns FE-analysis and design of a structure. The report forms part of the assessment for the grade awarded for the course. Detailed guidelines for the project assignment will be published in Canvas.

The course deals with selected topics relating to the durability and service life of large structures such as bridges, quays and offshore installations with service life requirements of more than 50 years. Reinforcement corrosion is decisive for the service life of concrete structures. Thus, degradation and damage caused by corrosion is an important topic in the course, but other relevant degradation mechanisms are also addressed. The course provides in-depth studies in topics such as:

• degradation and damage caused by corrosion
• modelling of transport and degradation mechanisms for reinforced concrete
• service life calculations and service life design of concrete structures
• condition assessments, remaining service life and service life extension of existing concrete structures.

Admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge:

The student:

· has advanced knowledge of relevant degradation mechanisms for steel and concrete and consequences for the service life and load-bearing capacity of structures.

· has in-depth knowledge of strategies, methods and calculation models used to achieve the prescribed service life (working life) of reinforced concrete structures.

· has in-depth knowledge of the structural consequences of reinforcement corrosion on the load-bearing capacity of concrete structures.

· is capable of assessing various measures to extend the service life and of using various calculation methods and models to estimate the remaining service life and capacity of existing concrete structures.

Skills:

The student is capable of:

· designing structures that fullfill the Eurocode requirements for durability and service life.

· carrying out service life predictions for concrete structures in marine environments.

· assessing the condition of and estimating the remaining service life and capacity of a relevant concrete structure.

· proposing measures to extend the service life of and repair methods for a relevant concrete structure

· carrying out capacity control of a damaged concrete structure or component.

General competence:

The student is capable of:

· acquiring new knowledge in the field and communicating it orally and in writing.

· understanding and analysing scientific publications on the topic of durability and service life of concrete structures.

· applying theories in practice based on scientifically justified choices of relevant solutions.

The teaching consists of lectures and exercises. In addition, the students will carry out a major project assignment in which they perform analyses and calculations of the service life and capacity of a concrete structure (or components thereof) exposed to relevant degradation mechanisms. The project assignment shall be presented in the form of a scholarly report. Detailed guidelines for the project assignment will be published on Canvas.

The development of sustainable, innovative building solutions relies on information from many sources and advanced calculations with good visualisations. It is not possible to achieve this without using building information modelling (BIM) and processes adapted to the use of digital tools. The course supports the operational use of the knowledge and skills that the students have acquired in the other courses in the programme.

The course provides a thorough review of the concept of BIM. It provides an overview of the development of digital programs, principles and processes and shows how BIM-based solutions can be used in different contexts. The course focuses on topics such as digital planning for the whole service life of a building (cradle to grave), BIM-based design and building processes, and BIM as a driving force for innovation and sustainability. The teaching emphasises cooperation with business and industry in the form of active enterprises, professional environments and research communities in the Oslo region.
