In-Plane Shear Behavior of Unreinforced Masonry Walls Strengthened with Fiber Reinforced Polymer Composites

by Sanaa El Malyh, Azzeddine Bouyahyaoui, Toufik Cherradi, Ancuta Rotaru and Petru Mihai

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 2, Page # 360–367, 2020; DOI: 10.25046/aj050247

Abstract:

Unreinforced masonry (URM) wall is one of the oldest types of walls used around the world. During earthquakes, URM walls present a real danger to life safety due to their behavior characterized by a brittle failure caused by their feeble shear resistance to in-plane loads, which make their strengthening necessary. Numerous studies had been used…

Analysis of Fuzzy Data for the Selection of Ingredients of the Polymer Composition by Technical Functions in Quality Management

by Ilya Vasilyevich Germashev, Tatyana Petrovna Mashihina, Evgeniya Vyacheslavovna Derbisher, Vyacheslav Evgenyevich Derbisher and Mikhail Alexeevich Kharitonov

Advances in Science, Technology and Engineering Systems Journal, Volume 4, Issue 3, Page # 88–99, 2019; DOI: 10.25046/aj040313

Abstract:

The task of fuzzy mathematical modeling of the composition of a polymer composition is singled out and formulated, as one of the types of chemical-technological systems for creating the theoretical foundations for managing the physicochemical properties of the material produced from this composition. Fuzzy data on the technical functions and concentration of individual ingredients that…
