The need for sustainable, environmental friendly, energy efficient construction materials could justify the interest on fibre cement board produced from recycled waste cardboard. Waste cardboard has a low production cost and could show an appropriate compatibility with hydrated cement particles. ...

The durability of concrete repairs is often limited due to restrained drying shrinkage. In this study, recycled tire rubber is used to develop deliberately low elastic modulus and highly ductile ECC repair material so as to alleviate repair failure induced by restrained drying shrinkage. Emphasis...

Membrane action of reinforced concrete (RC) beams is one of the primary mechanisms that enhances progressive collapse resistance of frames and influences the robustness of a structure under an unforeseen overload event. Compressive membrane action increases both the capacity and stiffness of long...

Output-only modal identification is needed when only structural responses are available. As a powerful unsupervised learning algorithm, blind source separation (BSS) technique is able to recover the hidden sources and the unknown mixing process using only the observed mixtures. This paper propose...

Multi-storey buildings made of cross-laminated timber panels (X-lam) are becoming a stronger and economically valid alternative in Europe compared with traditional masonry or concrete buildings. During the design process of these multi-storey buildings, also their earthquake behaviour has to be a...
Coupled Outdoor and Indoor Airflow Prediction for Buildings Using Computational Fluid Dynamics (CFD)
submitted by napimbreon 14 hours ago
The objective of this study is to investigate the accuracy of Computational Fluid Dynamics (CFD) for simultaneously predicting the outdoor and indoor airflows of single-cell and multi-storey buildings. Empirical models and two existing wind tunnel experimental data are used for validation. This s...

Wind loading and windborne debris (missile) impact are the two primary mechanisms that result in window glazing damage during hurricanes. Wind-borne debris is categorized into two types: small hard missiles; such as roof gravel; and large soft missiles representing lumber from wood-framed buildin...

The relation between basic and drying creep in tension compared to basic and drying creep in compression was investigated. The results obtained can be summarized as follows. Basic creep in compression is significantly more important than basic creep in tension. This difference increases with decr...

The mechanism of Alkali Carbonate Reaction (ACR) in concrete made from fine-grained, argillaceous dolomitic limestone coarse aggregates remains controversial. ACR distress is described as an increase in volume caused by the crystallization of brucite during the dedolomitization process. However, ...

Cracks induced by rebar corrosion are among the most important causes of performance deterioration in reinforced concrete elements. Even though several methods have been developed to detect the amount and location of corrosion-induced cracks, the sensitivity to small closed cracks located well be...
