Structural engineering
B - 6 Accuracy of measuring systems
The construction industry is in a state of change. Whereas in the past structures were inspected at regular intervals and measures were taken in the event of damage, in the future there will be a shift to predictive maintenance. This involves the continuous collection of measurement data and the use of prognosis models to predict the development of the condition of the structure. These prognosis models require a sufficient degree of accuracy of the measurement systems.
In a project/diploma thesis, approaches for the evaluation of the measurement quality (accuracy/precision and measurement uncertainty) are to be compared.

B - 5 Numerical investigation on the lap-splice length between Glass-Fiber-Polymer (GFRP) reinforcement and stainless steel reinforcement in concrete (applies to project work and master thesis)
Fibre-reinforced polymers (FRP) are used very successfully in many areas of technology and also facilitate particularly efficient, lightweight and economical components in the field of civil engineering. For instance, FRP reinforcements are characterized by high tensile strength, insensitivity to corrosion and very low thermal conductivity. Besides, have no electrical conductivity neither. Carbon fibre reinforced polymer (CFRP) and GFRP reinforcements can be advantageously used especially for slender, highly stressed concrete components and in aggressive environments. Experimentally verified knowledge of the composite load-bearing behaviour is required in order to design anchorage and lap lengths safely and more economically. The potential of these innovative materials shall be exploited.
In the scope of the ZukunftBAU project 0533_FVK_Verankerung, overlap tests between GFRP reinforcement and stainless steel reinforcement in concrete slabs were carried out. The bond strain and crack distribution were measured with distributed fibre optic sensors (DFOS). In this work, numerical simulations will be performed to validate the experimental results. A strategy shall be developed taking into account the property of nonlinearity of concrete and bond, the real boundary conditions and the dimensions of the specimens.

B - 3 Reinforcement optimization
Mathes Beratende Ingenieure GmbH is a successful engineering company in the design of structural engineering projects e.g. in the field of university, hospital, school or museum buildings. In the stressful daily engineering routine, assumptions and generalizations are often used for the design of the individual components, which lead to high reinforcement contents. These reinforcement contents may not be necessary from a structural point of view.
The task is to determine positions for a project or for a component from several projects where steel can be saved mathematically. The main focus should be on positions where the greatest savings potential exists from an economic point of view. As a result of the work, strategies or design templates should also be developed that make it easier for an engineer to apply the findings in everyday life and thus, if necessary, to design even more economical structures.
For the work our experienced engineers would be gladly available for questions. A workplace can also be set up in our Dresden office.

B - 2 Variant investigation bracing
Mathes Beratende Ingenieure GmbH is a successful engineering company in the planning of structural engineering projects, e.g. in the field of university, hospital, school or museum buildings. In most cases, the existing staircase or elevator cores are used for the bracing of buildings. However, for buildings with perforated facades, these wall plates with openings, for example, can also be used for the verification of the bracing.
The task is to investigate different bracing variants for a current project, e.g. by means of a 3D model. Manual secondary calculations also serve as plausibility checks. As a result of the work, the variants are to be compared in order to find the most economical solution. The required calculation and modeling effort should be included in this evaluation.
For the work our experienced engineers would be available for questions. A workspace can also be set up in our Dresden office.

B - 1 Design planning
Mathes Beratende Ingenieure GmbH is a successful engineering company in the planning of building construction projects, e.g. in the field of university, hospital, school or museum buildings. At the beginning of each project there is always the design phase with different variant investigations.
In the design phase, students have the opportunity to participate in current projects and to carry out various comparisons of variants, e.g. concerning the static systems or the execution of individual components.
If you are interested in participating in such a design process, we would be pleased to develop a suitable task for your project or diploma thesis together with you and a responsible person at the Institute for Solid Construction. This task can then be specifically adapted to the problems and projects currently at hand.
For the work our experienced engineers would be gladly available for questions. A workstation can also be set up in our Dresden office.
