Design and construction calculation of a regulation gate on a river dam

Namen magistrskega dela je izvesti analizo nosilnosti in dimenzioniranje jeklene konstrukcije regulacijske zaklopke na prelivnem objektu visokovodnega zadrževalnika Selška Sora. Jeklena konstrukcija je dimenzionirana skladno s standardom DIN_19704 ter Eurokod 3 in je izdelana iz materiala S355J2+N. V izračunu se je upoštevala obtežba vode v normalnem načinu obratovanja. Izvedla se je tudi analiza in izračun dvižni sil, ki imajo neposreden vpliv na samo nosilnost konstrukcije zaklopke. V okviru izračuna jeklene konstrukcije je bila izvedena analitična analiza posameznih elementov konstrukcije ter numerična analiza s pomočjo programskega paketa PrePoMax. Z potrebe določitve dvižnih sil zaklopke je bila izvedena analiza večfaznega toka vode čez zapornico.The purpose of the thesis is to carry out a load capacity analysis and dimensioning of a steel structure of a regulation flap gate at the overflow facility of the Selška Sora high-water reservoir. Steel structure is designed in accordance with DIN 19704 and Eurocode 3 standards and is made of S355J2+N structural steel. The calculation considers the water load under normal operating circumstances. The gate lifting forces, which have a direct influence on the load bearing capacity of the steel structure have also been analysed and calculated. The calculation of the steel structure involved an analytical analysis of individual structural elements and a numerical analysis using the PrePoMax software package. In order to determine the gate lifting forces, a multiphase water flow analysis across the flap gate was carried out
