Abstract

Käesolevas lõputöös on lahendatud Taebla autode remondihalli teraskarkass hoone põhilised kandekonstruktsioonid. Projekteeritud hoone kandekonstruktsioon koosneb 6 m sammuga terasraamidest. Raami postide sammud on vastavalt 10 ja 8 m. Raami postidele toetuvad nelikanttorudest katusesõrestikud. Karkassi kandeskeem on koostatud arvestusega, et hoone karkassi jäikus tagatakse kandva profiilpleki abil, mis töötab ühe jäiga horisontaalse plaadina ehk diafragmana ja mille liikumist takistavad karkassi postide vahele paigutatud diagonaalsidemed. Selle skeemi järgi ei ole ette nähtud jäigastavaid lisasidemeid katuse tasapinnas. Katusesõrestike ülemiste vööde nõtkumist külgsuunas takistab kandev profiilplekk. Profiilplekki arvutus on teostatud RUUKKI Poimu programmiga, milles on diafragmaefekt arvesse võetud. Kuna profiilplekk on toetatud sõrestiku ülemise vöö peale kogu ulatuses tekib ülemises vöös lisaks pikijõule ka paindemoment. Lõputöös teostati arvutused teraskonstruktsioonielementide ristlõigete leidmiseks, raudbetoonist vundamentide dimensioneerimist lõputöös ei käsitletud. Katuse kandvaks profiilplekiks valiti Ruukki T130M-75L-930 klassiga S350GD+Z. Lahendatud ferm on koostatud nelikanttoru ristlõigetest küljepikkusega 50…80 mm. Nelikanttorud on seinapaksusega 3…5 mm. Nelikanttorude terase tugevusklass on S355J2H. Arvutatud postide profiiliks valisin 100×100×5 nelikanttoruprofiili. Kasutatava terase tugevusklass on S355J2H. Fermi sisejõudude arvutamiseks on kasutatud arvutiprogrammi Autodesk Robot Structural Analysis Professional 2019. Dimensioneeritud karkassi osad on esitatud töö graafilises osas.

Abstract [en]

The purpose of this thesis is to calculate the main steel structures of a warehouse building type. The thesis consists of five chapters, each of them deals with various aspects, that are affecting the calculation of steel structures. The first chapter is an introductory part. The introductory part is divided into three sections, in the first section different standards used in the work are described, in the second - used programs, the third part reveals the architectural design solution of the building. The second chapter describes loads that are affecting the building and calculation of combinations of these loads. The chapter consists of three sections. The first section includes the snow load calculation, the second - the effect of the wind load and the third takes into account the loads caused by the weight. The third chapter is also divided into two sections. In the first section described, the load-bearing sheet calculations, as it also gives the building stiffness. In the second section, the calculation of the load-bearing capacity of the elements and assemblies of the lattice is shown on the example of one truss. The fourth chapter reveals the calculation of a steel frame column and its support knot. The summary is written in fifth chapter. The goal of the thesis is achieved. The author recommends checking the structures according to the second calculation scheme, to decide which one is more efficient in terms of finances and time.
