IMPROVEMENT OF AN ANALYTICAL MODEL FOR DETERMINING THE LOAD-CARRYING CAPACITY OF TIMBER-STEEL CONNECTIONS WITH DOWEL-TYPE FASTENERS
The second generation of Eurocode 5 is in preparation and has not yet been adopted, so the calculation of the load-carrying capacity of timber-steel connections is based solely on the rules of the first generation. Currently, load-carrying capacity is determined using expressions for thin or thick steel plates. For cases in between, linear interpol...

REKONSTRUKCIJA ZIDANE KONSTRUKCIJE HOTELA: ASPEKTI SEIZMIČKOG PRORAČUNA I MERA OJAČANJA
Rad se bavi rekonstrukcijom zidane konstrukcije postojećeg hotelskog objekta sa aspekta seizmičkog proračuna i definisanja adekvatnih mera ojačanja. Analizirani su postojeće stanje konstrukcije, identifikacija kritičnih zona i procena nosivosti prema aktuelnim propisima. Poseban fokus je na modeliranju zidane konstrukcije i uticaju nepravilnosti na...

UKLANJANJE GLAVNOG RASPONA SUPERSTRUKTURE STAROG SAVSKOG MOSTA-PROJEKTANTSKI I IZVOĐAČKI ASPEKTI
Stari savski most bio je ratni most u centru Beograd, izgrađen 1942. godine od strane Nemačkog Rajha, radi održavanja veze preko reke Sava, nakon rušenja Mosta kralja Aleksandra. Prvobitno namenjen kao privremena konstrukcija za vojni transport, služio je kao glavni tramvajski most do 2020. godine. Uzimajući u obzir stanje čelične konstrukci...

MACHINE LEARNING-BASED PREDICTION OF CONCRETE COMPRESSIVE STRENGTH FOR STRUCTURAL ENGINEERING APPLICATIONS
The increasing availability of experimental data in civil engineering has created new opportunities for the application of artificial intelligence techniques in structural engineering research. Machine learning approaches provide powerful tools for identifying complex relationships between material composition and mechanical properties. In this stu...

REPRESENTATIVE MODULUS OF SUBGRADE REACTION FOR STRUCTURAL DESIGN OF INDUSTRIAL FLOOR SLABS – A CALIBRATION-BASED APPROACH
The Winkler model is the most widely used approach for the structural design of industrial floor slabs because of its simplicity and implementation in commercial software. However, selecting a representative modulus of subgrade reaction remains a major source of uncertainty. Conventional methods usually derive this parameter from predicted settleme...

NONLINEAR ANALYSIS OF (UN)BRACED STEEL FRAMES SUBJECTED TO HORIZONTAL LOAD
This paper presents a 2D nonlinear analysis of the load-carrying capacity of unbraced and concentrically braced steel frames subjected to lateral loading. The study was conducted using the incremental ("step-by-step") analytical method and finite element analysis. The effects of material and geometric nonlinearities, axial force, and brace cross-se...

PROJEKTOVANJE DRVENIH KONSTRUKCIJA PREMA EVROKODU 8: KLJUČNE IZMENE U DRUGOJ GENERACIJI
Razvoj poglavlja o drvenim konstrukcijama u Evrokodu 8 pokazuje postepeni prelazak od veoma konzervativnog pristupa ka savremenom konceptu seizmičkog projektovanja zasnovanom na duktilnosti i disipaciji energije u spojevima i vezama. U EC8 druge generacije uvrštena su pravila za nove inženjerske drvene proizvode, uvedena je detaljna klasifik...

STATIC TENSILE FACTORY ACCEPTANCE TESTING OF THE OVM.ST15-47 PARALLEL-STRAND HANGER SYSTEM FOR THE NEW SAVA BRIDGE IN BELGRADE, SERBIA
This paper presents the full-scale static tensile factory acceptance testing of the OVM.ST15-47 parallel-strand hanger system intended for installation on the New Sava Bridge in Belgrade, Serbia. Each tested hanger assembly consisted of 47 seven-wire prestressing strands, with a nominal tensile strength of 1,860 MPa and a nominal cross-sectional ar...
