Chair of Solid Construction

The Chair of Concrete Structures offers courses in the civil engineering degree programs leading to the Bachelor of Science (B.Sc.) and Master of Science (M.Sc.) degrees.

The modules in the Bachelor's degree course cover the fundamentals of design and construction in reinforced concrete construction as well as an introduction to prestressed concrete construction. The Master's degree course focuses on prestressed concrete construction and special areas of solid construction. In addition, courses are offered in the fields of bridge construction, structural design in existing structures and FE applications in solid construction. Construction site excursions are regularly organized to extend and deepen the courses.

Further opportunities for in-depth study exist within the framework of student research projects and final theses. These are often related to current research topics being worked on at the Chair of Concrete and Masonry Structures. Furthermore, practical tasks with a scientific approach are offered.

SWR Aktuell in conversation: How at risk of collapse are bridges in Germany?

After the partial collapse of the Carola Bridge in Dresden, the question arises: What is the state of bridges in the country? Many were built after the Second World War and may not be designed for today's traffic. Bridge researcher Torsten Leutbecher's assumptions also point in this direction. However, the professor of solid construction at the University of Siegen gives the all-clear in an interview with SWR Aktuell: "You can't deduce from this that collapses are regularly associated with them. After all, we also have a parallel system for monitoring buildings". Changes such as cracks are detected at an early stage during regular checks so that a collapse like the one in Dresden can be avoided. SWR Aktuell presenter Gerald Pinkenburg spoke to bridge researcher Leutbecher about what such inspections look like and how safe they are - also with regard to cost-cutting measures from politicians.

Shear cracking tendency and shear load-bearing behavior of prestressed bending beams made of steel fiber-reinforced ultra-high performance concrete

In contrast to reinforced concrete components with shear reinforcement, there is still no generally recognized model for components without shear reinforcement that can be used to consistently capture the load-bearing mechanisms under shear loading. A comparison of different approaches and model concepts shows that the load-bearing components of the uncracked concrete compression zone, from crack interlocking or crack friction and from the dowel effect of the longitudinal reinforcement are interpreted and weighted differently.

Rotational capacity of plastic bending crack joints in combined reinforced UHPFRC bending beams

The rotational capacity of plastic zones characterizes the ductility of reinforced/prestressed concrete bending beams and enables the redistribution of stresses in statically indeterminate structures. It is not easy to transfer existing models for predicting the rotational capacity of reinforced/prestressed concrete bending beams to UHPFRC bending beams, as UHPFRC bending beams are generally additionally reinforced with steel fibers.

Services

With its expertise and technical equipment, the Chair of Concrete and Masonry Structures is available to the construction industry, public building authorities and civil engineering firms. The range of activities covers the entire field of structural and civil engineering. A particular focus is the integration of innovative high-performance materials.
