QUANTITATIVE ANALYSIS OF ADDITIONAL TEMPERATURE STRESSES IN CONTINUOUSLY WELDED RAILS: INFLUENCE OF BRIDGE EXPANSION LENGTH
In this paper, the influence of bridge expansion length on the distribution of additional temperature stresses in continuously welded rails is investigated. Using a representative railway viaduct as a case study, the effects of thermal interaction between the track and the bridge are analyzed. The research focuses on the design phase, particularly ...

AUTOMATIZATION OF STRUCTURAL DESIGN OF ANEMOMETRIC GUYED MASTS USING SAP2000 MATLAB OAPI
This paper presents the application of a MATLAB-based framework that automates the modelling, analysis and design of anemometric steel guyed masts via the SAP2000 Open Application Programming Interface (OAPI). The design procedure is carried out in accordance with the current generation of Eurocode standards. The efficiency of the OAPI is demonstra...

REDUCING CARBON EMISSIONS THROUGH CIRCULAR USE OF WASTE GLASS IN CEMENTITIOUS MATERIALS
The use of finely ground waste cathode ray tube (CRT) glass as a partial replacement for cement directly links the principles of circular economy with the reduction of carbon dioxide emissions. Instead of ending up in landfills, glass is returned to the production cycle as a pozzolanic material, reducing the need for extracting natural resources an...

TORSION AND WARPING CONSTANT FOR STEEL I BEAMS WITH BATTEN PLATES
A reliable calculation method for torsion constant (IT) and warping constant (Iw) of I section with batten plates is presented. As welding of the batten plates transforms the cross section from an open to a two-cell closed one, the associated torsion theory becomes rather complex. St. Venant torsion theory of thin-walled closed sections is extended...

A CAD-BASED REFINED ZIG-ZAG THEORY FINITE ELEMENT FRAMEWORK USING GMSH SOFTWARE
A computational framework for the structural analysis of laminated composite plates is presented. The framework combines geometry and mesh generation in Gmsh software with a Refined Zig-Zag finite element solver written by the author. The imported mesh provides the discretization of the computational domain, while the laminate definition, material ...

METHODS FOR DETERMINING MASONRY COMPRESSIVE STRENGTH: FROM EXPERIMENTS TO AI APPROACHES
The compressive strength of masonry walls represents one of the key mechanical characteristics of masonry structures. Its determination goes beyond a simple consideration of the properties of individual materials and depends on the complex interaction between masonry units, mortar, assembly geometry, and loading conditions. This paper presents a sy...

IZAZOVI OCJENJIVANJA POTRESNE OTPORNOSTI POSTOJEĆIH ZGRADA
Potresi koji su 2020. godine pogodili Zagreb i Petrinju pokazali su visoku seizmičku ranjivost postojećeg fonda zgrada u Republici Hrvatskoj, posebno starijih zidanih građevina izgrađenih prije uvođenja suvremenih protupotresnih propisa. U radu su prikazani osnovni elementi procjene seizmičkog rizika, problematika identifikacije kritične tipologije...
