Aging buildings, congested infrastructure and rising performance demands are increasing the need for reliable, efficient strengthening solutions. This presentation highlights a modern retrofit approach for reinforced concrete structures that combines high-performance FRP composites with thin UHPC overlays to boost flexural, shear and confinement capacity with minimal thickness, rapid installation and high durability. Built around an intuitive three-step framework – Assessment → Strengthening → Validation – the session reviews key design principles from ACI 440, 562 and 318, and introduces MAPEI Structural Design (MSD), a cloud-based tool for streamlined, code-aligned FRP and UHPC calculations. Real-world case studies – including UHPC column jacketing, FRP beam strengthening and composite bridge girder rehabilitation – demonstrate design rationale, construction sequencing and performance outcomes, offering engineers practical insight into delivering reliable, durable and low-disruption retrofit solutions.

Presenter:

Luca Albertario Luca Albertario is a Regional Product Line Manager at MAPEI S.p.A. in Milan, Italy, leading the Building & Structural Strengthening line for North and South America. A civil engineer specializing in structural design, he has been with MAPEI since 2011, focusing on composite strengthening systems, concrete repair and masonry rehabilitation. He works closely with engineering and product teams to support major projects, guide R&D and oversee development of the MAPEI Structural Design software. Luca has contributed to post-seismic assessments and rehabilitation efforts in Italy and abroad, with experience spanning concrete, masonry, timber and steel structures. He is an active member of ACI Committees 440 (FRP) and 239 (UHPC) and frequently provides technical training to support the adoption of advanced strengthening solutions.
