Research

The Department of Solid Structures deals with questions on fundamental problems of reinforced and fiber-reinforced concrete, especially with regard to components made of ultra-high-strength concrete with combined reinforcement, masonry under seismic loading, and special areas of the foundation of offshore wind turbines.

The focus is on the following research topics:

• Tensile behavior of UHPC with combined reinforcement of fibers and steel bars.
• Bottle-shaped compression fields
• Compressive-transverse tensile strength of unreinforced/reinforced or combined reinforced concrete slabs
• Flexural strength of UHPC with combined reinforcement
• Shear force bearing behavior of UHPC with combined reinforcement
• Anchorage and spanning of non-prestressed reinforcement in UHPC
• Experimental and numerical investigations of reinforced UHPC components under pure torsion
• Punching shear behavior of slabs made of UHPC
• UHPC reinforcement in columns of normal strength concrete

Other research fields of the department include the topics:

• Nonlinear calculations of reinforced and prestressed concrete structures and comparison with tests on structural members.
• Structural members made of high-strength concrete (HPC) and ultra-high-strength concrete (UHPC)
• Applications of concretes in the foundation of offshore and onshore wind turbines
• Concrete structures for environmental protection
• Material models (e.g. multi-axial behavior of fiber reinforced concrete)
• System identification of reinforced and prestressed concrete structures
• Non-destructive testing methods
• Innovative production technology
• Cracking behavior of reinforced and prestressed concrete structures
• Earthquake resistance of concrete and masonry structures
• Composite construction
• Cracking problems in solid structures
• Supervision/monitoring of prestressed concrete bridges
