Bio
Pavlo Vehera was born in 1991 and is currently residing in Ukraine. From 2007 to 2011, he studied at Lviv Polytechnic National University, earning a bachelor's degree in civil engineering. He continued his studies from 2011 to 2013, obtaining a master's degree and successfully defending his thesis on strengthening reinforced concrete eccentrically compressed columns with CFRP materials. After completing his master's, Pavlo entered postgraduate studies, which he finished in 2017 with a thesis on the shear bearing capacity of reinforced concrete beams strengthened with FRCM materials under load.
Since 2017, he has been teaching at the Department of Building Constructions and Bridges at Lviv Polytechnic National University. Pavlo Vehera became the head of the Scientific Society of Students, Doctoral Candidates, and Young Researchers at the university in 2019. To date, he has published over 50 scientific articles, with 22 of them indexed in Scopus and WoS. He is also the author of two utility model patents in Ukraine.
Pavlo Vehera has been involved in national grant-funded research, including projects on strengthening reinforced concrete structures with composite materials and methods for calculating structures under real operating conditions. He was awarded the Cabinet of Ministers of Ukraine Scholarship for young scientists for 2020-2022 and was named the best young scientist at Lviv Polytechnic University in 2021. In 2022, Pavlo received the academic title of associate professor at the Department of Building Constructions and Bridges, and in 2023, he became a laureate of the Regional State Administration and Regional Council Award for employees of scientific institutions and higher education institutions in the Lviv region.
Research on the Effectiveness of Strengthening Methods of Reinforced Concrete Beams on the Shear by Composite Materials, Considering the Load Acting on the Constructions
This project focuses on analyzing experimental data from investigations of shear behavior in reinforced concrete beams strengthened with the FRCM system under load. The main experimental research was conducted at Lviv Polytechnic National University, with some results already published. The study involved variables such as the presence of internal transverse reinforcement, different methods of strengthening with varying amounts of P.B.O. fabric, and different levels of active load. The goal of this project is to present and analyze the results, identify the strengths and weaknesses, and determine further research needs through scientific seminars and consultations with international researchers.
A secondary objective is to create mathematical models for these tests, an area not yet explored. This will involve reviewing existing studies and modeling with modern software. The outcome will be computer models of the experimental studies and expanded models based on feedback, leading to an algorithm for practical structural strengthening applications.
The final goal is to refine a calculation model for shear-strengthened reinforced concrete beams, based on current building codes, and to develop methods for calculating crack openings, stiffness changes, and deflections. This will provide a comprehensive analysis of the test samples. Consultation with other experts will enhance the quality of this research. Ultimately, this work will improve my skills and contribute to the reconstruction of Ukraine, setting a foundation for future research and enhancing scientific standards in the country.
