NUMERICAL THERMAL ANALYSIS OF WIND TURBINE FOUNDATIONS WITH A FORCED CONCRETE COOLING SYSTEM
Wind turbine foundations belong to the category of massive concrete structures, in which controlling the temperature rise during the early stage of concrete hardening is of crucial importance for preventing cracks caused by thermal tensile stresses. This paper presents an example of a staged thermal analysis of massive wind turbine foundation withi...

OVERVIEW OF SCHOOL BUILDING CONDITIONS IN RURAL AREAS – LAZAREVAC MUNICIPALITY
Rural primary schools within the Municipality of Lazarevac represent a significant portion of the public building stock. Most of the buildings are single-storey with load-bearing masonry systems, built in the second half of the 20th century according to the technical regulations of that period, which did not seismic resistance, durability, and ener...

THE ROLE OF FINANCING AVAILABILITY AND TIMING IN CONSTRUCTION PROJECT PERFORMANCE
The construction sector plays an important role in economic development but is highly sensitive to financial constraints during project implementation. While existing studies mainly focus on the sources of financing, less attention has been paid to the availability and timing of financial flows throughout the project lifecycle. Delays in financial ...

DESIGN OF NEW REINFORCED CONCRETE ARCH BRIDGE OVER THE ĐETINJA RIVER
This paper presents the design of a reinforced concrete arch bridge over the Đetinja River canyon, part of the Užice bypass route in Serbia. The 292 m long structure features a main arch span of 162 m with a rise of 23,6 m (rise-to-span ratio 1/6,86), placing the deck approximately 90 m above river level. The rationale for selecting a relatively sh...

AI-BASED FINANCIAL RISK AND COST PREDICTION FRAMEWORK FOR CONSTRUCTION EXPERIMENTS: A CASE STUDY OF STEEL HALL ASSEMBLY
This study proposes an artificial intelligence-based framework for financial risk assessment and cost prediction in construction experiments, focusing on steel hall assembly processes. Construction experiments involving real-time monitoring technologies are associated with significant financial uncertainty. Proposed framework combines cost modeling...

NADZOR NAD RUŠENJEM ČELIČNE HALE: SLUČAJ HALE KONVERTORA I RAFINACIJE TOPIONICE U BORU
Rekonstrukcija objekta metalurgije, radi proširenja proizvodnog kapaciteta, nekad zahteva ojačanje, rušenje i građenje čelične i/ili armirano-betonske konstrukcije. Rušenje konstrukcije je rizičan posao, koji zahteva dosta iskustva. Kinesko preduzeće “Ciđin” (ZiJin) otpočelo je rekonstrukciju Topionice i Rafinacije ...

TESTING OF MASONRY WALLS FOR STRUCTURAL CONDITION ASSESSMENT AND MASONRY STRUCTURE DESIGN
The assessment of existing masonry structures requires reliable information on their actual material properties, stress state, stiffness, and load-bearing capacity. This paper presents a methodology for the investigation and characterization of existing masonry walls, combining visual inspection, laboratory testing of masonry units and mortar, and ...

LONG TERM DURABILITY OF CONCRETES PREPARED WITH CRYSTALLINE ADMIXTURES
Concrete is the most used construction material worldwide and material with the second greater consumption globally, just after water. However, durability of concrete is a major problem that minimizes the service life of structures. Concrete deterioration is almost always caused by reactants that penetrate the concrete matrix with water. Therefore,...

FROM CATASTROPHE TO RESILIENCE: FORENSIC INSIGHTS AND PREDICTIVE STRATEGIES FOR SUSTAINABLE INFRASTRUCTURE MAINTENANCE
Major infrastructure failures rarely originate from a single defect, but emerge when deterioration, unfavorable load paths, limited redundancy, increasing operational demand, and incomplete knowledge interact. This paper synthesizes forensic and life-cycle evidence from two collapses: the 2018 Polcevera Viaduct in Genoa and the 2021 Champlain Tower...
