“…Serviceability limit state is the deciding state for design of a number of structures (see for e.g. Kamiński, Pawlak 2011;Juozapaitis et al 2013;Majcher et al 2014). Bearing in mind stability problems of steel structures, the buckling of slender members can reach high values, which may adversely affect the use of the structure.…”

The paper deals with the analysis of reliability of a hot-rolled steel IPE-beam designed according to Eurocodes. A beam at its ultimate limit state is considered. The load acting on the beam consists of permanent and long-term single variation actions. The beam is loaded with end bending moments about the major principal axis. The beam is susceptible to lateral torsional buckling between the end supports. Reliability of the beam is assessed using probabilistic analysis based on the Monte Carlo method. Failure probability is a function of the random variability of the loadcarrying capacity and the random variability of load effects. The variability of the load-carrying capacity is influenced by the variability of initial imperfections. Imperfections are considered according to experimental research. Numerical studies showed that the failure probability is significantly misaligned. High values of failure probability were obtained for slender beams, for beams loaded only by permanent load action, and for beams loaded only by long-term single variation load. In further studies the values of partial safety factors of load and resistance were calibrated so that the failure probability had a target value of 7.2E-5. Relatively high values of partial safety factors were obtained especially for beams with high slenderness.

“…The use of rigid cables is one of the methods for ensuring the stiffness of the suspension bridge and for reducing kinematic displacements (Grigorjeva et al, 2010a;Juozapaitis et al 2010Juozapaitis et al , 2013. The simplified methodology for calculating the classical symmetric single-span bridge with rigid cables is provided in (Grigorjeva et al, 2010a).…”

Suspension bridges are characterized by exceptional architectural expressions and excellent technical and economic properties. However, despite all advantages, suspension bridges have a few negative features. Suspension bridges with flexible cables share excessive deformation caused by the displacement of kinematic origin. In order to increase the stiffness of suspension bridges, an innovative structural solution refers to rigid cables used instead of the flexible ones. The paper describes a methodology for calculating an asymmetric single-pylon suspension bridge with rigid cables considering installation features. Also, the article presents the numerical simulation of the bridge and determines the accuracy of the proposed methodology.

“…The employment of rigid cables is one of the most effective ways to make a suspension bridge stiff enough (Grigorjeva, Juozapaitis, & Kamaitis, 2010a;Juozapaitis, Idnurm, S., Kaklauskas, Idnurm, J., & Gribniak, 2010;Juozapaitis, Kliukas, Sandovič, Lukoševičienė, & Merkevičius, 2013). Variations in the ratio of cable rigidity to girder stiffening may result in a reduction of the vertical displacements of the bridge and assist in providing rigidity for the complete structure.…”

The article presents the results of the numerical analysis of the asymmetrical one-pylon suspension bridge built-in rigid cables. The models for the suspension bridge with the cables of different rigidity are analyzed by comparing vertical displacements, bending moments and strains in the structural members of the bridge. The numerical analysis was performed by examining the bridge under symmetrical and asymmetrical loading and different erection methods. The stress-strain state of a single asymmetrical pylon with the cables of different rigidity and the rational relationship between cable rigidity and girder stiffness has been established.
