In-plane cyclic behaviour of RC frames strengthened with composite sandwich panels
Autor: Christoph Fernandes Sousa, João R. Correia, Joaquim A. O. Barros
This paper presents an experimental study about the development of a sustainable and multifunctional composite sandwich panel for the rehabilitation of reinforced concrete (RC) buildings from the 1960s to the mid-1980s. For this purpose, the cyclic b

Autor: Christoph Fernandes Sousa, Felipe Melo, Inês Costa, Tiago Valente, Joaquim A. O. Barros
Publikováno v: RILEM Bookseries ISBN: 9783030765460
The present work describes an integrated approach that leads to the development of a new model capable of describing the tensile behavior (mode I) of fiber reinforced concrete (FRC), considering the orientation of the fibers, the fibers segregation a
