Abstract

Töö „Ühelöövilise tööstushoone põhielementide lahendused kahe hoone pikkuse korral“ sisaldab pealkirjas nimetatud hoonete projekteerimiseks vajalikke kandepiirseisundi arvutusi ja esitleb elementide valitud lahendusi. Elementideks on vundamendid, postid, katusesõrestikud, otsaseina talad, katuse serva pikisidemed ja tavapäraselt kasutatavad seinte jäikusdiagonaalid. Hoone poste vaadeldakse kahe arvutusskeemi kohaselt, milleks on konsoolpost ja alt pöördumatu ning ülalt liigendkinnitusega post. Teine versioon on ehituslikult odavam lahendus nii posti enda kui vundamendi osas. Esimene lahendus on traditsiooniliselt sobilik pikkadele hoonetele, teise kasutamine on mõeldav lühemate hoonete puhul, kus katus mingil viisil piisavalt jäigaks saadakse. Katust jäigastava lahendusena on töös pakutud varrassidemed katuse pinnas, mille kasutusvõimalusi on uuritud ka pikema hoone puhul ning leitud, et see võiks olla reaalne ka hoone plaaniliste mõõtude suhte 1:5 korral. Erilise mahuna lisanduvad jäikusdiagonaalid ja pikisidemed sõrestike vahel, mille tulemusel on võimalik hoida ehituskuludest kokku, sest odavam on investeerida mõlema hoone puhul katuse jäigastamiseks sidemetesse kui suurema mahulisi raudbetoonist konstruktsioone rajada. Arvutused on tehtud nii käsitsi kui kasutades üldlevinud programmi ARSA. Arvutuste tulemusena on valitud betoonkeha mõõdud ja armeering, töös esitatakse lõpplahenduse kontroll.

Abstract [en]

The Solutions of the Basic Elements of a Single-Span Industrial Building in the Case of Two Building Lengths contains calculations of bearing-state conditions necessary for design of the buildings mentioned in the title and presents the chosen solutions of the elements. The frame bridges of the buildings are the same, but the lengths have the five-fold difference. For long buildings, the traditional console post work schedule is used. However, in the case of a short building, the work scheme provides for the articulated postal support. The axial dimensions for a shorter building are 24 * 24 m and for a longer building 24 * 120 m. The clean height of both rooms is 10 meters from the floor. The highest elevation of the roof framing is expected to be 1/10 of the span, i.e. 2.4 m. The paper contains the dimensioning of reinforced concrete foundations and posts, the choice of a load-bearing profile sheet, the design of the arched girder and the control of rods, the control of the horizontal and diagonal rods of longitudinal and side walls and the potential roof framing for both buildings. In addition, the action of horizontal framing on posts has been investigated, where the sufficient stiffness of the roof structure can be regarded as a permanent support of the post. As the roof reinforcing solution, the author of the research proposed rod joints in the roofing surface, the use of which has also been investigated in the case of a longer building, and it appeared to be realistic in 1: 5 ratio for planned dimensions of the building. The rigidity diagonals and longitudinal joints between the framing add special volume, thus reducing the cost of construction, as it is cheaper to invest in the roof reinforcement joints as a basis than to build larger voluminous reinforced concrete structures.
