Contents and qualification goals:

Contents of the module are analysis and recalculation as well as repair and strengthening of existing solid structures.
After completion of the module, students will be familiar with the methods of structural diagnosis using computational and experimental methods. They are able to analyze existing solid structures with regard to their condition and load-bearing behavior and to plan and calculate the necessary strengthening measures. Reinforcement with the aid of textile concrete is also a focal point.
After completing the module, students will have in-depth knowledge of modern concrete technology in the construction of existing and new buildings, particularly with regard to the production, properties and areas of application of high-performance concretes with and without fiber reinforcement.

Teaching methods:

4 SWS lecture and 2 SWS exercise

Prerequisites for participation:   

The competences to be acquired in the modules of the basic studies (BIW1-01 to BIW1-11) and the basic subject studies (BIW2-02 to BIW2-06) are required.

Applicability:

In the undergraduate diploma program in civil engineering: Compulsory elective module in the main course of study, in particular for the specialization in structural engineering In the postgraduate course of study in civil engineering: Compulsory elective module, in particular for the specialization in structural engineering.

Requirements for the award of credit points:

Credit points are earned if the module examination is passed. The module examination consists of one written examination (240min).

Credit points and grades:

8 credit points can be acquired through the module. The module grade results from the arithmetic mean of the grades of the examination performances.

Frequency of the module:

Module is offered every academic year, starting in the winter semester.

Workload:

The total workload is 240 hours.

Duration of Module:

7th semester: 2SWS lecture Reinforcing of solid structures.
8th semester: 2SWS Exercise Reinforcement of solid structures
8th semester: 1SWS lecture High performance concretes
8th semester: 1SWS lecture and 1SWS exercise measurement and testing technology

Lecture

Introduction

  • Objectives (durability, reuse, strengthening)
  • Differences new / existing construction

Historical development in reinforced concrete construction

  • Development of concrete and reinforced concrete construction method
  • Typical historical solid construction
  • Development of standards
  • Historical building materials (steel, concrete)

Maintenance of structures

  • Condition development of structures
  • Preservation strategies

As-built analysis

  • Procedure
  • Investigation methods

Computational evaluation of the structural safety

  • Internal forces redistribution
  • Ultimate limit state method
  • Experimental structural safety assessment

Reinforcement of solid structures

  • Textile concrete

For copyright reasons, the information material accompanying the lecture is only accessible to the participating students. Login and password will be announced in the lecture. 

Exercise

The exercises will mainly deal with practical examples. It is shown how the analysis and evaluation of existing structures is carried out and which basic possibilities of further procedures exist. In addition to the technical possibilities, questions of economic efficiency and sustainability will be considered.

Voucher

No voucher is provided.

Exam

The lecture will be completed with a written exam (240min).
