| Abstract [eng] |
Master thesis contains detailed structural part project of the pedestrian footbridge in Mažeikiai. Including analysis of requirements for new building constructions governed by the substantive legal requirements. Footbridge natural fluctuation frequencies in vertical and horizontal projections has to be established. Briefly described essential technological processes for assembly main steel beam of footbridge. Professional risk during assembling was evaluated. The structures design part is based on the construction design Eurocodes and national annexes LST EN 1993-2 Eurocode 3: Design of steel structures - Part 2: Steel bridges, LST EN 1992-1 Eurocode 2: Design of concrete structures - Part 1-1: General rules and rules for buildings and STR 2.05.05: 2005 and annex 5 to this regulation. Axial forces and natural frequencies in elements identified by a special Robot Structural Analysis 2015 software. Structures sensitive to dynamic effects require a dynamic analysis. Having clearly defined the nature of the action of loads inducing oscillations, structures are often designed in a manner allowing the avoidance of possible resonance. Established values of the natural frequencies were compared with the range of intolerable values specified in LST EN 1991-2:2006 Eurocode 1: Actions on structures - Part 2: Traffic loads on bridges. |
