WIND TUNNEL STUDY OF WIND-INDUCED LOADING ON AN ISOLATED SOLAR PANEL
Solar panels (SPs) are designed to withstand wind-induced loading, characterised by varying wind speeds and directions, as well as high turbulence. This paper examines force coefficient statistics—mean, standard deviation, 3-s gust and peak values—on an isolated SP model, using data from an experimental campaign conducted in the atmosph...

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...

PARTICLE SIZE AND DENSITY EFFECTS ON HEMP–LIME REINFORCEMENT EFFICIENCY
Hemp–lime composites are sustainable bio‑based materials with excellent hygrothermal performance and carbon sequestration potential, but their high porosity limits mechanical strength and broader use. This study examines the influence of fiberglass mesh reinforcement on the compressive behavior of hemp–lime composites with different par...

PROBABILISTIC ASSESSMENT OF AN EXISTING REINFORCED CONCRETE BRIDGE
This study presents a probabilistic assessment of an existing four-span reinforced concrete slab bridge, considering the stochastic variations of concrete strength and the yield strength of reinforcement steel. Although Eurocode permits probabilistic assessment of existing bridges, it provides limited practical guidance. Bending and shear limit-sta...

RESILIENCE-BASED SEISMIC DESIGN: FROM THEORY TO ENGINEERING PRACTICE
Current seismic building codes aim to protect life safety by allowing controlled damage to lateral-load-resisting systems. Although this approach prevents collapse, buildings may remain unusable and impose significant consequences on communities and infrastructure. Resilience-based seismic design seeks to reduce these impacts, yet challenges remain...

SAFETY ASSESSMENT OF EXISTING CONCRETE RAILWAY BRIDGES FOR 150-YEAR SERVICE LIFE
The sustainable rehabilitation of existing reinforced concrete railway bridges is gaining importance as transportation infrastructure approaches the end of its original design life. Reusing existing concrete substructures instead of complete replacement offers substantial environmental and economic benefits but requires robust assessment and target...
