CALCULATION FOR ROOF CONSTRUCTION OF SPORTS HALL IN BRIJEŠĆE

Zadatak diplomskog rada, iz kolegija Drvene konstrukcije II, je bio izračun krovne konstrukcije sportske dvorane u Briješću. Tlocrtne dimenzije dvorane su 22,85 x 33,90 m. Krovna konstrukcija je izvedena kao jednostrešno krovište sa referentnom visinom objekta 10,37m i srednjim nagibom krovne plohe 6°. Glavni nosači su tipski lijepljeni lamelirani nosači izvedeni kao zakrivljeni lamelirani nosači sa rasponom 22,10m. Materijal glavnih nosača je lijepljeno lamelirano drvo kvalitete GL24h. Sekundarni nosači su podrožnice, kvaliteta materijala podrožnica je puno drvo C24.Prostorna stabilizacija krovišta je izvedena kao sustav mekih dijagonala Ø27 mm kvalitete čelika S235. Analiza djelovanja na konstrukciju izvršena je prema normama HRN EN. Za proračun i dimenzioniranje podrožnica, glavnih nosača i horizontalnih spregova, korištena je norma HRN EN 1995-1-1. Unutarnje sile, reakcije i progibi, dobiveni su u programu Robot Structural Analysis Professional 2014, a grafički prilozi napravljeni su pomoću programa AutoCAD 2016.The task of the graduate thesis, from the course of Wooden Construction II, was to calculate the roof construction of the sports halls in Briješće. The floor plan dimensions of the hall are 22.85 x 33.90 m. The roof structure is constructed as a monopitched roof with a reference height of 10.37 m and the average roof pitch of 6 °. The main girder are type-glued laminated girder constructed as curved laminated girder with a range of 22.10 m. The material of the main girder is glued laminated quality wood GL24h. Secondary girder are purlin, the quality of purlin material is a solid timber C24. Spacious roof stabilization is performed as a system of soft diagonals of Ø27 mm steel quality S235. The constructional performance analysis was calculated out according to HRN EN standards. The HRN EN 1995-1-1 standard was used to calculate and dimension the purlin, main girder and horizontal joints. Inner forces, reactions and deflection were calculated in the Robot Structural Analysis Professional 2014 program, and the graphical attachments were created using the AutoCAD 2016 program
