Sekundarni naslov: Full strength connections in seismic resistant buildings
Sekundarni povzetek: In this thesis we analyzed the response of joints, which were designed as a full strength. Different configurations of joints have been designed. All joints were reinforced with added ribs. We analyzed the overall response of joints, which means the position of the center of compression, forces in bolts, bending the end-plate and the emergence of contact pressure between end-plate and column flange. We also analyzed the influence of the level of bolt preload on the response of joints. Based on the changes in the thickness of the end plate, we studied the development of contact pressure and, consequently, changes in bolt forces. In real situation, these compressive axial forces in columns are present, so we analyzed their impact on the response of the joint. In the joint, designed with haunch we analyzed the response of the joint in which we changed the haunch’s stiffness. We have also performed the analysis, where we changed the column profile. Column flanges were additionally reinforced by adding backing plates. In calculating the design value of yield stress of dissipative elements, factor 1,1 is used. It captures the effects of steel hardening. We performed the analysis, where we presented a numerical model where steel hardening was consider. We determined if factor 1,1 is appropriate. Based on the findings, we made recommendations for designing full- strength bolted column-beam joints in seismic resistant buildings.

Povzetek (ePrints): V diplomski nalogi smo analizirali odziv spojev, ki so bili zasnovani kot polno nosilni. Kot polno nosilne so bile zasnovane različne konfiguracije spojev. Vsi spoji so bili ojačani z ojačitvenimi rebri. Analizirali smo celoten odziv spojev, kar pomeni lego nevtralne osi, velikosti sil v vijakih, upogib čelne pločevine in pojav kontaktnih napetosti med čelno pločevino in pasnico stebra. Analizirali smo tudi vpliv prednapetja na odziv spoja. Na podlagi spremembe debeline čelne pločevine smo preučevali razvoj kontaktnih napetosti in posledično spremembe na sile v posameznih vrstah vijakov. Dejansko so v stebrih prisotne tlačne osne sile, zato smo analizirali njihov vpliv na odziv spoja. Pri spoju, zasnovanem z vuto smo preučevali vpliv togosti vute. Izvedli smo tudi analize, kjer smo zamenjali profil stebra. Na območju spoja smo uporabili podložne ploščice in analizirali njihov vpliv na odziv. Spoj smo aplicirali tudi na primer vmesnega stebra in spremljali odzive. Pri izračunu projektne vrednosti meje tečenja za disipativne elemente je uporabljen faktor 1,1 , ki zajame vplive utrjevanja. Izvedli smo analize, kjer smo v numerični model podali utrjevanje in na podlagi odziva spoja analizirali, ali je faktor 1,1 ustrezen. Na podlagi zaključkov smo podali priporočilo za projektiranje polno nosilnih vijačenih spojev steber-prečka.
