Compared to other structural systems, cable-stayed bridges are marked by their exceptional architectural appeal. However, these bridges have several disadvantages – their deformability under asymmetrical or local loads the relatively significant...

Tunnelling is one of those disciplines that is extremely dependent on assumptions made in the design phase, which can then be subject to major deviations in the construction phase. These deviations can lead to major delays in the construction...

Construction companies lack junior staff for construction management. However, according to a Germany-wide survey of students, the profession lacks attractiveness. The conflict between the traditional job profile and the current desires of junior...

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...
