Comments on “Prediction on CO uptake of recycled aggregate concrete”, Frontiers of Structural and Civil

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1504-1506 doi: 10.1007/s11709-021-0782-0

Abstract: A methodology to compute the CO2 uptake of recycled aggregate concrete is proposed in the commented paper. Besides some typos in several formulas, it is found that the approach to estimate the specific surface area of the recycled aggregates is not correct. This issue has some impact in the conclusions of the commented paper. Therefore, aiming to improve the understanding, accuracy and findings of the commented paper, an alternative approach to estimate the specific surface area of the recycled aggregates, as well as an erratum of the formulas and revised conclusions are suggested.

Windborne debris damage prediction analysis

Fangfang SONG, Jinping OU,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 3,   Pages 326-330 doi: 10.1007/s11709-010-0067-5

Abstract: Windborne debris is one of the most important causes of the envelop destruction according to the post-damage investigations. The problem of windborne debris damage could be summarized as three parts, including windborne debris risk analysis, debris flying trajectories, and impact resistance of envelope analysis. The method of debris distribution is developed. The flying trajectories of compact and plate-like debris are solved by using a numerical method according to the different aerodynamic characteristics. The impact resistance of the envelopes is also analyzed. Besides, the process of windborne debris damage analysis is described in detail. An example of industrial building is given to demonstrate the whole method by using the observed data of typhoon Chanchu (2006). The method developed in this paper could be applied to risk assessment of windborne debris for structures in wind hazard.
