I am delighted that the second scientific paper of my PhD research (in cooperation with my colleagues of the structural mechanic group of the University of Cagliari, Marco Zucca, Antonio Cazzani, Daniel Meloni, Emanuele Reccia) has been recently published in Thin-Walled Structures. This study shows how to model and understand the enhancement in structural behaviour of the edge corrugation in shallow spherical shells (such as the one designed by P. L. #Nervi in Rome - #flaminio dome), also taking into account non-linearities. If you are interested in our paper, you can download it for #free until the 7th of October 2023, using this link: https://lnkd.in/d-h3-zRr.

Excellent Handbook of Wood Science and Technology. The Wood and Mositure Chapter is a super good reference for understanding the fundamentals of wood and water interactions. #wood #mositure

At Oregon State, researchers like Erica Fischer, assistant professor and the John and Jean Loosley Faculty Fellow, are researching real world solutions to real world problems. Mass timber is a composite construction material of glued wood elements comparable to concrete or steel. It is, however, combustible. Fischer will be leading a study where rooms will be built with mass timber, furnished, and then lit on fire to study the effect on the structure. The research will help determine how to design mass timber structures that are safe. https://beav.es/TfU

I am pleased to share our latest paper published in the ACI Structural Journal titled ‘Structural Behavior of Low-Carbon and Functionally Graded Concrete One-Way Slab Strips’, co-authored by my wonderful supervisors: Dr. Josh Woods, PhD PEng, Dr. Evan Bentz, and Dr. Neil Hoult! You can read it at the following link: https://lnkd.in/eqYhhmAa This study investigates the structural performance one way slab strips made of lower carbon concrete and different types of functionally graded (layered) concrete in comparison to conventional concrete. Results indicated little to no structural behavioural differences between lower carbon and conventional concrete, as well as slight enhancements in stiffness from functionally graded concrete.

Hello everybody, I want to share an article [link](https://lnkd.in/eRgiVWvz) about the prediction of the physical-mechanical properties of roller-compacted concrete pavements under different service and mix conditions based on cement and water content. This research aims to propose multiple regression equations to calculate the physical-mechanical properties of RCC pavement under different services (grams of water vapor per kilogram of air) and mix conditions (cement content and water-cement ratio). Authors: Julián Pulecio-Díaz, Miguel Sol-Sánchez and Fernando Moreno-Navarro Further research on the subject is welcome!

POSIZIONI DI DOTTORATO – STRUCTURAL CONSOLIDATION INTERVENTIONS USING INNOVATIVE MATERIALS FOR THE PRESERVATION OF HISTORICAL AND MONUMENTAL MASONRY BUILDINGS Università degli Studi di Firenze Deadline: 12/07/2024 ore 12.00 The Italian historical and monumental built heritage, which represents an enormous socio-cultural and economic asset, is mostly comprised of buildings with load-bearing masonry structures. As is well known, the mechanical characteristics of this material depend on several factors, including the properties of the constituent materials, the brickwork, the quality of the structural connections, etc. However, its most peculiar characteristic is the low tensile strength compared to the compressive one. This often leads to buildings being vulnerable to applied forces, particularly seismic actions. Therefore, the analysis and development of specific intervention procedures are proposed, based on the use of composite and other innovative materials, to mitigate vulnerability of masonry structures. The research will be carried out through specific experimental investigations as well as the development of appropriate predictive models. https://lnkd.in/db4hieDk Ref.: Mario Fagone, mario.fagone@unifi.it

🎉 Exciting News Alert! 🎉 I'm thrilled to announce the publication of our research article entitled "Spatio-temporal characterisation of local scour around a circular bridge pier in cohesive soil with different clay/silt ratio" in the European Journal of Environmental and Civil Engineering! Our research focuses on the changes in the temporal evolution of local scour hole's characteristics as the clay/silt ratio increases. The investigation is conducted through physical experiments. The findings demonstrate that a clay content ranging around 7.5%-10% marks the threshold at which cohesive soil behavior begins to significantly influence the scouring process. Moreover, the results show that SRICOS-EFA method works well for predicting the temporal evolution of the maximum scour depth measured in laboratory. A special thanks to my co-authors and the research team for their dedication and expertise in bringing this study to fruition! 📖 For those interested, you can access the full article here:  https://lnkd.in/ek_i-py7 #AcademicPublication #Research #flumetest #scour #cohesivesoil #foundationdesign #bridgeengineering

With my colleague Dina Ali We accomplished our impressive paper focuses on the response of concrete shear wall reinforced by shape memory alloy (NiTi). Important findings were presented experimentally and numerically. The theses has been published in high ranked journal.

I want to invite you to read one of my latest publications about a new synthetic porous silica-based aerogel material (aMBx - aerogel modified bituminous materials) that we developed at Arizona State University (ASU) for the improvement of asphalt pavements. The pavement temperature gradient was found to be lower for aMBx-modified pavements along most of the entire structure. This concludes that the aMBx-modified asphalt pavements, with lower thermal conductivity (k), have lower thermal susceptibility and therefore are less prone to thermal cracking.
