Abstract
Diplomová práca sa zaoberá návrhom, respektíve vytvorením protinávrhu k existujúcej konštrukcii, diaľničného mosta na diaľnici D1 v úseku Jánovce – Jablonov v okrese Levoča na Slovensku, ktorý premosťuje miestnu komunikáciu. Hlavným cieľom práce bol návrh, analýza a posúdenie nosných prvkov mostovky. Pre účely tejto práce sa vypracovali tri varianty premostenia. Pre podrobnú analýzu sa vybral variant, kde nosnú konštrukciu mostovky tvoria dodatočne predpäté tyčové prefabrikované nosníkmi zmonolitnené spriahnutou železobetónovou doskou. Analýza zvoleného variantu bola prevedená na dvoch matematických modeloch. Prvý model bol priestorová 3D dosko-stenová konštrukcia. Tento model slúžil zistenie čiara priečneho roznosu ostatného stáleho zaťaženia a premenného zaťaženia. Druhý, rovinný 2D model, slúžil na zistenie účinkov dotvarovania, zmršťovania a relaxácie výstuže od dlhodobých účinkov zaťaženia v definovaných časových uzloch. Výstupy z vyššie uvedených modelov poslúžili na analýzu a posúdenie nosných prvkov mostovky a návrh predpínacej a betonárskej výstuže.
This master thesis is focused for design, respectively for creating counterproposal of existing structure of Motorway Bridge located at D1 motorway between Jánovce and Jablonov in district Levoča in Slovakia. This bridge is over a local road. The main aim of this thesis is design, analysis and assessment of bearing elements of bridge deck. For purposes of this thesis was created three variants of bridge deck. Detailed analysis was performed on bearing construction from post-tensioned precast beam with monolithing concrete slab. Two mathematic models were used for analysis of chosen variant. First model was spatial 3D shell construction. The purpose of this model was determinate cross spreading line of other constant load and live load. Second, flat 2D model, was for determination creep and shrinkage appeared from long-term load. These effects were observed in at advanced defined time nodes. Outcomes from upper mentioned model were used from design and assessment of bearing elements of bridge deck, design prestressed reinforcement cables and concrete reinforcement rods.
