Internal pressure resulted from accumulated depth of placed concrete is imposed on vertical formworks such as walls and columns.
15 sty 2014 · Understanding the complex interactions of the building pressure field - the air pressure regime within and surrounding the building - helps explain the increasingly common failures related to: indoor air quality, sick building syndrome, building related illness;
24 sie 2023 · Civil engineering structures are designed to sustain various types of loads and possible combinations of loads that could act on them during their lifetime. Accurate estimation of the magnitudes of these loads is a very important aspect of the structural analysis process.
20 wrz 2018 · This paper gives a (p)review on a more advanced active control of properties of concrete, based on the application of external signals to trigger an intended response in the material, either in fresh or hardened state. Current practices in concrete industry that could be considered as active control are briefly summarized.
Form pressure is the pressure generated by fresh concrete as it is poured inside the formwork system during construction, and it is the decisive factor in formwork design, as the formwork must...
9 paź 2024 · Where, c min = minimum cover according to EN 1992-1-1 4.4.1.2; Δc dev = allowance in design for deviation according to 4.4.1.3; Now, we won’t dive deep into how to calculate c min and define Δc dev, because it’s an article itself.And most countries have the minimum values defined in textbooks for the different reinforced concrete elements, concrete types and environmental conditions.
20 mar 2014 · The available methods for calculating the formwork pressure for the flowable concrete and SCC are based on measuring the shear strength of concrete using different concepts, such as the setting time of concrete or the structural build-up at rest.
