Abstract In recent past, the authors developed an innovative modular system for low rise building made by structural sandwich panels. This system was conceived with the focus on the rationalization of the construction process and on the thermal efficiency of the building. Thus, the precast panels comprise two outer Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) layers, a thermal insulation material and Glass Fibre Reinforced Polymer (GFRP) connectors. Studies previously made by the aut...

This paper presents the results of fire resistance tests on carbon fiber-reinforced polymer (CFRP) strengthened concrete flexural members, i.e., T-beams and slabs. The strengthened members were protected with fire insulation and tested under the combined effects of thermal and structural loading. The variables considered in the tests include the applied load level, extent of strengthening, and thickness of the fire insulation applied to the beams and slabs. Furthermore, a previously developed nu...

This paper addresses the efficiency of thermal insulation layers applied to protect structural elements strengthened by fiber-reinforced polymers (FRP) in the case of fire event. The paper presents numerical modeling and nonlinear analysis of reinforced concrete (RC) columns externally strengthened by FRP and protected by thermal insulation layers when subjected to elevated temperature specified by standard fire tests, in order to predict their residual capacity and fire endurance. The adopted n...

The fire performance of reinforced reactive powder concrete (RPC) beams has raised much concern due to the sensitivity of these beams to high temperature and relatively lower fire resistance. To achieve the fire-resistance ratings as specified in building design codes, a fire insulation layer is often required. However, very limited research has been conducted on the effect of fire insulation on the fire resistance of reinforced RPC beams. Hence, using the commercial software ABAQUS, a three-dim...

Abstract Precast concrete sandwich panel (PCSP) is introduced to improve the thermal performance of solid concrete panels by sandwiching an insulation layer between the concrete layers or wythes. The two concrete layers are connected through the insulation using C-shape shear connectors. The shear connector makes these concrete wythes to act as one panel and allow it to be a load-bearing sandwich panel to carry lateral force. In PCSP, material and arrangement of connectors influence both thermal...

Abstract The effect of thermal insulation materials on the drying of structures has been studied in this paper. The drying times are especially important for structures having fresh concrete layers that have to be dried out before they can be coated and finished. The presented work includes numerical simulation studies carried out for general material properties of common thermal insulation materials. The simulation studies were carried out for typical concrete wall structures: Concrete sandwich...

Abstract Energetically critical points in thermally insulating building envelopes are caused by penetrations of building interior concrete slabs through the envelope insulation layers to create external balconies. A new highly insulating balcony thermal break element has been developed which enables both structural continuity and thermal insulation in the envelope’s insulation layer. The element is composed of combined structural and thermally insulating AFRP/GFRP loop and sandwich components. T...
