This paper presents a new approach to calculate the elastic lateral-torsional buckling moment of I-beams with sinusoidally corrugated webs. The appropriate hand calculation methods to determine the elastic critical moment of corrugated web beams...

Based on shear tests on 16.5 m long prestressed concrete girders, the influences of load type, cross-section shape, degree of restraint, stirrup reinforcement and prestressing on the shear capacity are analysed. The experimental investigations...

Despite significant further developments in the verification methods in stage 2 of the recalculation guideline, some existing structures can still only be verified using scientific methods in stage 4 due to the higher traffic loads and the changed...

The article presents the verification procedures in stage 2 for the recalculation of existing bridges according to the current BEM-ING Part 2 and their further development. Based on the design models of BEM-ING Part 2 for shear and torsion, further...

Due to increasing traffic loads and different design rules in newer standards, significant deficiencies occur in the shear capacity check of existing prestressed concrete bridges. Therefore, verified analytical models based on realistic experimental...

With the expectation of achieving higher load-bearing capacity, the shear force verification is occasionally carried out at Level 4 of the recalculation guidelines in accordance with the formulation of the Canadian standard. Especially for existing...

In the present paper, advanced verification methods are investigated with regard to the evaluation of existing prestressed concrete bridges under shear force bending and additional torsion. The procedures are based on a more accurate analysis of the...

Cost targets are missed in 72 % of factory planning projects and time targets in 60 %. This is mainly due to inadequate communication and coordination between those involved in planning. To meet these challenges, new methods and tools must be used...

In recent years, temperature increases, temperature fluctuations and heavy rainfall events have led to an increase in extreme rock avalanches and landslides. In their runout areas, these lead to flow-like mass movements that endanger settlement...

In 2019, the bearing capacity of shaft grouted ductile piles in a typical Viennese soil, the Quaternary sediments, was investigated based on their load-deformation behavior as part of the research project „Unteres Hausfeld 2”. Large-scale tests...

For laboratory investigations, 3D laser scanning technology can now be used for more targeted examination of steel components. The principle of 3D laser scanning is that a laser beam is projected onto a surface by a scanner and the reflected rays...

Carbon-reinforced concrete offers new construction capabilities compared to classical steel-reinforced concrete. In order to exploit these, strategies are developed that aim at a material-minimised design and machine-aided manufacturing methods....

Carbon concrete as a material substitute for reinforced concrete must prove itself. The question arises as to how sustainable this building material combination is. In addition to the ecological perspective, this question can also be answered from...

Material modeling of concrete using modern numerical methods significantly accelerates the design process of structures. However, for multiscale modeling of such a heterogeneous material, the established homogenization methods are still very...
