Flexural Test of a Composite Beam Using Asymmetric Steel Section with Web Openings
Publication: Journal of Structural Engineering
Volume 135, Issue 4
Abstract
As the number of high-rise buildings increases, the floor-to-floor height has been considered as a significant component due to limited city areas. To reduce the floor-to-floor height, a newly developed composite beam using asymmetric steel section with web opening was proposed and experimentally explored. Shear connectors are not used for the proposed composite beam. Instead, longitudinal shear strength is obtained through the bond strength of the interface between concrete and steel, and the bearing strength of the opened web area. In this paper, the flexural behavior of the proposed beam was assessed using the simple beam test. For comparison, a slim floor beam was tested. A bare steel beam was also tested to evaluate resistance under construction loads. The proposed system showed satisfactory horizontal shear resistance and good composite behavior.
