Abstract
U ovom radu razmatrat će se okvirni nosač ukliješten na dva slobodna kraka. Nosač se sastoji od tri grede koje se razlikuju u dužinama (l1,l2 i l3) i aksijalnim momentima tromosti (Iy1, Iy2 i Iy3), nosač je također podijeljen u četiri segmenta gdje su grede zasebno opterećene vanjskim opterećenjima koja djeluju na čitav okvirni nosač. U prvom segmentu nosač nema vanjskog opterećenja, u drugom segmentu nosač je opterećen kontinuiranim opterećenjem q, u trećem segmentu nosač je opterećen silom F1 , te u četvrtom segmentu silom F2. Ovakav okvirni nosač statički je neodređen jer je broj nepoznatih vrijednosti u vezama veći od broja neovisnih jednadžbi koje se mogu raspisati za ovakav sustav. U ovom proračunu koristit će se svojstvo asimetrije gdje će se nosač rastaviti po simetrali na dva okvirna nosača, a vanjska opterećenja će se prenijeti, u jednoj varijanti, simetrično gdje će se za proračun koristiti metoda pomaka, a u drugoj varijanti asimetrično gdje će se za proračun koristiti metoda sila. U ovom radu korištenjem metoda sila i pomaka potrebno je odrediti u prvoj i drugoj varijanti reakcijske sile i momente u pojedinim karakterističnim točkama i nacrtati dijagram unutarnjih sila, te na kraju zbrojiti dobivene vrijednosti obije varijante kako bi se dobile vrijednosti sila i momenata u tim točkama za zadani okvirni nosač. Ovaj rad obuhvaća proučavanje literature i rješavanje raznih zadataka i sličnih primjera kako bi se steklo znanje pri rješavanju ovakve problematike.
Abstract (english)
The thesis was made through observation and analysis of a frame beam with two fixed supports on each side. Frame beam is made out of three beams that are different in lengths (l1,l2 and l3) and axial moment of inertia (Iy1, Iy2 and Iy3), frame is also separated into four segment in which each beam has its own external load which stresses entire frame beam. First segment there is no external loads, second segment is pressured by continuous load q, third segment is loaded with concentrated force F1 and finally the fourth segment with force F2. Frame beam is statically indeterminate because the number of unknown values of forces in reactions, internal or external, are larger than number of independent equations which express equilibrium condition. In this calculation property of symmetry is going to be used, where in symmetrically loaded version displacement method has to be used and in asymmetrically loaded version force method has to be used. In this final thesis using displacement method and force method it is required to calculate reaction forces and moments in characteristic areas and also draw diagram of internal forces and after its been done for each variant separately those two need to be added up to get total loads that stress the beam. This final thesis requires studying literature and practicing similar problems in order to get enough knowledge on working with these types of problems.
