Fracture Characterization of Masonry in Compression with Acoustic Emission Analysis and Numerical Modeling KU Leuven
Masonry under compression exhibits complex structural interactions among brick units and mortar joints which remains a true challenge to understand.
Its structural response is related to the relative mechanical properties of the bricks/blocks, the mortar and their interface. In this research, experimental and numerical analysis will be applied to deduce information on the fracture progress in masonry under compression. An extensive ...
The Determination of transport properties in carbonate rocks with high-resolution CT and NMR. KU Leuven
Continental carbonates are studied because of their reservoir potential. Especially with the recent discovery of microbialite and travertine oil fields in the Pre-Salt (offshore Brazil) and in the Namibe basin (Angola), the importance of continental carbonates as reservoir rocks for future hydrocarbon production was highlighted. Quaternary continental carbonates from quarries in Denizli (Turkey) and from Sütt# and Budakalász (Hungary) were ...
Objective and subjective assessment of rain noise in rooms covered by structural skins KU Leuven
There is a great motivation for architects to apply structural skins including ETFE cushions to cover large spaces such as sports halls, swimming pools, shopping malls, airports, and/or different atria. The incentive lies behind interesting material properties, namely little weight, transparency, thermal performance, and sustainability. In terms of acoustics, ETFE cushions also have very special characteristics which made them almost ...
Human echolocation inside buildings KU Leuven
Auditory information plays an important role in the perception of the architectural environment in which we reside, this is critical for visually impaired people. Acoustical signals are important for communication, but they also allow us to form a mental image of the structure of our surrounding, and of the sound sources in our vicinity. Moreover, an appropriate acoustical environment is crucial for our feeling of comfort and pleasantness. In ...
Acoustic Emission-based Assessment of Reinforcement Corrosion: Damage Monitoring and Bond Modelling of Corrosion Effects in Reinforced Concrete KU Leuven
Reinforcement corrosion is believed to be the major deterioration phenomenon in reinforced concrete (RC) structures, causing large direct and indirect financial costs. While tools for modelling and design of new RC structures are mature, methods for modelling and assessment of the remaining structural capacity of existing RC structures are much less developed. A prerequisite for the assessment of these structures is the development of ...
Development of a methodology for predicting the acousticperformance of built-up wall and floor systems at high frequencies KU Leuven
Lightweight systems such as cross-laminated timber elements, sandwich panels, gypsum board walls,... are emerging in building construction. Because of their relatively low weight and complex vibro-acoustic behaviour, achieving a sufficient level of sound insulation with such systems is however challenging. The aim of this research is to develop a sound transmission loss prediction method, which exhibits similar accuracy as a comparable ...
