Lightweight structures, cementitious composites, sandwich panels


Conceptual design of lightweight fa├žade system for renovation and new buildings

The increasing energy and insulation regulations created a strong need for low-energy building solutions. In these regulations special attention is fixed on the U-values of walls (and roofs). By 2020 only net-zero new buildings will receive a building license, so U-values of 0,15 W/m2K are not unimagible. The required insulation thickness will thus strongly increase, leading to mechanical challenges on different levels.

In this context sandwich panels have gained a strong interest of the building industry. Sandwich panels are composed out of two thin and stiff face-elements, interconnected through a lightweight (insulating) core. They are generally characterized by a high bending stiffness and strength in comparison with their relatively low weight. Nowadays structural insulating panels (SIP) are already used to create some dwellings of two storeys. However due to the lack of knowledge on both the material as the structural level a secondary redundant bearing structure is added, which makes that these systems are not competitive to traditional building solutions.

The research in this thesis comprises the design and analysis of a sandwich loadbearing wall, both for renovation and new building issues. Focus will lie on optimising the structural performance by using high performance Textile Reinforced Cement (TRC) faces. First of all the mechanical behavior of the sandwich panels will be investigated. Analytical and numerical models will be elaborated to predict the structural behavior. To validate these models experiments are conducted. Besides these mechanical properties also the durability study is an important issue to look at.  To characterize the properties of the sandwich panels on the long term durability tests (freeze-thaw and heat-rain) and cyclic loading will be performed, this by means of freeze-thaw and heat-rain cycles. To be competitive to traditional building solutions these sandwich panels need be optimized, leading to the most cost-effective solutions. To fulfil strength and deflection criteria certain parameters need to be studied during this optimization procedure, f.e. number and place of supports, thickness of the faces, etc.
