The Faculty of Engineering at the University of Kerbala discusses in a scientific study the structural behaviour of self-pressed concrete box beams with openings in place via an electronic application.
The study, submitted by the student, Saif Ali Hassan, aims at identifying the behaviour of hollow cords made of self-stacking concrete containing non-reinforced or reinforced on-site slots using reinforced carbon steel strips through the implementation of laboratory and theoretical work by the ABACOS program.
The discussion deals with a non-linear analysis using the Abacus finite element analysis program to perform the numerical verification of hollow self-pressed concrete lintels with or without the presence of non-reinforced or reinforced site holes using strips of reinforced carbon plastics.
The thesis indicates that there is a good convergence between the practical and theoretical results in terms of final load, maximum deviation, and load deviation curves, in addition to this the pattern of strengthening the bottom edge by reinforced carbon strips was the best in terms of maximum strength of hollow lintels containing close holes on the cushions or in the middle of the lintel, when compared to the non-reinforced lintels.
