Energy certification of new buildings was introduced in the Republic of Serbia as a mandatory procedure in 2012. In addition to civil engineers, eligibility to take the professional examination and issue Energy Performance Certificates (EPCs) is granted to architects, mechanical engineers, and electrical engineers who have completed at least 300 EC...

The CONNECT4C project promotes circular construction through the development of adaptable and reusable steel joints that combine structural robustness with the requirements of practical engineering design. The project focuses on innovative moment-resisting joint concepts incorporating components such as “long bolts”, “sliders&rdqu...

The paper presents the RELAR project, with the aim of improving the assessment of losses and the recovery process after an earthquake. The project is based on the application of machine learning methods and image recognition techniques to speed up the damage assessment process and increase the accuracy of remediation cost estimates. The limitations...

This paper presents an automated workflow linking a voxel-based block-in-matrix (BiM) ground model to PLAXIS 2D through its Python HTTP API, focusing on finite element (FE) simulation of tunnel excavation in such heterogeneous rock. Building on prior borehole-constrained ground model and conditional random field (CRF) matrix-variability studies, th...

The seismic performance of existing reinforced concrete (RC) buildings is a critical concern, especially for structures designed prior to the implementation of modern seismic design provisions. This paper presents the Japanese JBDPA Standard (2001) as a comprehensive framework for the seismic assessment of existing RC buildings. The methodology emp...

Kod vitkih konstrukcija, odvajanje vrtloga izaziva oscilacije upravne na pravac strujanja vetra. U ovom radu izvršen je proračun maksimalnih amplituda poprečnih oscilacija primenom Pristupa 1 Priloga E Evrokoda 1-4 (SRPS EN 1991-1-4), na primeru reflektorskog stuba visine 39.3 metra u fazi izgradnje, bez reflektorske opreme. Rezultati pokazu...

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...

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...

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...

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...
