This book provides the latest developments in the field of engineering structures, with particular emphasis on experimental testing, numerical modelling and simulation, and structural health monitoring, as presented at the 1st International Conference on MOdelling, TEsting and MOnitoring of Engineering Structures (MOTEMOES), held in Piacenza, Italy, on July 9-10, 2026. It covers a broad blend of topics, which includes steel structures and connections, reinforced concrete and cements, masonry, timber, geo-materials, FRP/FRCM/TRM/SRG for structural rehabilitation, computational and experimental fracture mechanics, computer-aided design and manufacturing, electro-thermal modelling of composites, analysis and testing of natural fiber reinforcement systems, probabilistic modeling of materials and structures, non-destructive testing NDT, health monitoring in existing structures, failure of materials and structures, durability, etc.
