Numerical Modelling of Buildings
Numerical modelling is a process whereby computers are used to reproduce the behavior of buildings.
Standard numerical modelling techniques use the finite element method, with linear elasticity analyses performed to reproduce non-complex structures.
However, to reproduce certain specific behaviors of structures, such as instability (buckling), cracking, contact between structures and long-term behavior, non-linear models must be used. INGPHI has the tools and knowledge required to perform all these different analyses, which are particularly useful for establishing the safety level of structures, predicting their behavior in the case of seismic activity, analyzing vibrations and predicting long-term behavior.
BIM – Working Methods and Applications
BIM stands for Building Information Modelling, a comprehensive system for modelling information (or data) for buildings.
More than anything else, it is a working method, a collaborative process between construction operatives based around a digital model. This 3D database contains smart and structural data that can be used for analyses, checks, plans, visualizations and the optimization of projects, with the scale ranging from the smallest details to whole neighborhoods, including buildings, bridges and infrastructure connecting them.
UHPFRC and fiber reinforced concrete applications
Fiber reinforced concrete contains steel, synthetic or natural fibers randomly distributed within the cementitious matrix. The fibers help controlling cracking of the concrete. In particular, UHPFRC (Ultra High-Performance Fiber-Reinforced Concrete) is a material with a compact cementitious matrix reinforced with short steel fibers. UHPFRC is known for its outstanding mechanical performances. It is characterized by a very high compressive strength and a hardening and softening behavior in tension. Moreover, UHPFRC has a very low permeability which makes it very durable when exposed to water and deicing salts.
With its remarkable properties, UHPFRC is appropriate to strengthen and protect existing structures as well as for new structures.
Building façades represents a major challenge in contemporary architecture. That’s why the firm’s team has engineers specialising in the field. In the context of sustainable development, the design of façades is intimately linked to a building’s energy performance, and façades are also becoming increasingly varied, expressive and complex.
