Étude de marché

Une étude de marché est une activité d'exploitation marketing destinée à analyser, comprendre et mesurer le fonctionnement réel des forces à l'œuvre dans le cadre d'un marché. Il s'agit d'une activité typiquement mise en œuvre dans le cadre de la démarche du marketing management. Concrètement — une fois établi le périmètre à observer — cela recouvre l'étude des comportements, des appréciations, des besoins et des attentes des demandeurs et offreurs présents sur ce marché, ainsi que celles des conditions selon lesquelles ceux-ci agissent (ou non) pour réaliser les échanges correspondants à la satisfaction de leurs buts et intérêts. Les études de marché utilisent des techniques quantitatives telles que le sondage, les panels, et des techniques qualitatives telles que les entretiens individualisés, les réunions de groupes.

Thin UHPFRC slabs without conventional reinforcement as light-weight structural elements

Aurelio Muttoni, Dario Redaelli, Ana Spasojevic

Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) is a material characterised by significantly improved mechanical and durability properties compared to other concretes. In recent years, an important research effort has been made to identify appropriate structural forms and to provide practical design rules allowing efficient UHPFRC structures to be conceived. This paper presents the results of an experimental and theoretical study on the structural behaviour of thin UHPFRC slabs without conventional reinforcement. It is shown that these elements can provide high bending resistance, and, applied in an appropriate structural arrangement, lead to strong and light-weight structures that cannot be built with ordinary reinforced concrete. The favourable behaviour of thin UHPFRC members results from material mechanical properties: high compressive strength and significant ductility in tension of thin UHPFRC members lead to a ductile bending response, even when conventional reinforcement is not provided. It is demonstrated that the theory of plasticity can be safely used to assess the bending failure load for thin UHPFRC slabs. A practical expression is proposed to define the resistant plastic moment, allowing an easy estimation of the bending load-bearing capacity of thin statically indeterminate UHPFRC elements. The results are compared with experimental data on slabs of various thicknesses, showing good agreement.

Model-based interpretation of floor vibrations for indoor occupant tracking

Slah Drira, Yves Sylvain Gilles Reuland, Ian Smith

Information regarding occupant flows inside buildings is beneficial for applications such as thermal-load control, market research and security enhancement. Existing methodologies for occupant tracking involve data-driven techniques that rely either on radio-frequency devices, optical sensors or vibration sensors. Such data-driven techniques suffer from ambiguous interpretations, especially in presence of obstructions and varying floor rigidities. In this contribution, an occupanttracking strategy using footstep-induced vibrations is outlined. The goal is to incorporate information from physics-based models in the interpretation of vibration measurements. Using error-domain model falsification (EDMF) a single occupant is localized using the vibrations resulting from footstep impacts and using various shoe types. EDMF is a multiple-model approach that provides a set of candidate locations from an initial population of possible footstep locations. Model responses that contradict footstep-induced vibration measurements are rejected through incorporating several sources of uncertainty from measurements and modeling. Occupant-trajectory identification is then performed based on the candidate-location set for each detected footstep using a sequential analysis that combines information from consecutive footsteps. A full-scale case study is used to evaluate the methodology. Model-based occupant tracking that includes structural information and takes into account systematic errors and model bias has the potential to identify accurately single occupant locations in a full-scale structure.
