Analysis and Development of Advanced Sandwich Elements for Sustainable Buildings
Building industry represents nearly 40 % of primary energy consumption in most countries registered in the International Energy Agency. This makes the building sector the highest energy consuming sector in industry worldwide. To fulfil energy reduction objectives, European Union (EU) countries and companies are looking for solutions to lower the energy demands from the building sector. Therefore, ambitious targets for energy consumption of new buildings are being implemented, and by the year 2020 nearly zero energy buildings will become a requirement in the EU. As a consequence of these requirements as well as general requirements for increased efficiency and sustainability, the building sector is experiencing a growing demand for modular, lightweight building elements having a high degree of insulation, a long life time, a low CO2 emission, a low consumption of raw material, and an attractive surface with minimum maintenance. The need for improvement, innovative structures and production methods therefore grows. In this challenging environment, precast thin-walled High Performance Concrete (HPC) Sandwich Panels offer an interesting solution to all actors involved in the value chain of the building, from the architects and the manufacturers to the end owners. However, the literature available with respect to analysis and/or design of thin-walled HPC sandwich panels is scarce. The goal of this work was to develop a framework for analysis and optimization of the precast thin-walled High Performance Concrete Sandwich Panels. The present framework was led at three levels. The first level experimentally investigated material and mechanical properties of shear connectors, insulation layer and HPC. Material characterization included assessment of time dependent strength, fracture properties, stiffness and shrinkage for HPC. In a second stage, the structural level was described to study the influence of the various constituents of the sandwich panel on the behaviour of the panel under shear and bending loading. The ...
