| Abstract | |
This study aims to investigate the contribution of the steel bars to the flexure capacity and to promote the composite behavior in partially encased composite beams. The study includes an experimental investigation of partially encased beams under bending in four points and a numerical simulation using the computer package DIANA® to collect data from the behavior of partially encased composite beams with longitudinal reinforcement. Four models of partially encased composite beams were tested and two variables were analyzed: rate of longitudinal reinforcement in concrete and position of stud bolts. The experimental results showed the efficiency of the junction between reinforcing bars and stud bolt to the increase the bending capacity of the partially encased beam and to obtain the steel-concrete interaction. The numerical simulation has good agreement with the experimental results. (AU) | |
