Abstract
Finite Element Modeling and Nonlinear Analysis on the Optimum Opening Location for Continuous Composite Beams with Web Openings
Highlights
As a transverse bearing component, composite beams have been increasingly widely utilized in civil and industrial infrastructure
In addition to the common research on ultimate bearing capacity and deformation capacity of composite beams with web openings, this study considers the influence of opening locations on the plasticity performance, vertical shear distribution and bending moment redistribution of continuous composite beams
1) With increasing load (Fig. 9b), the concrete slab at the web opening region bears most of the sectional shear force, while the steel beam bears a small part of the shear force
Summary
As a transverse bearing component, composite beams have been increasingly widely utilized in civil and industrial infrastructure. The continuous composite beam is a statically indeterminate structure, which means that the opening's influence is limited to some contents of the supported beams mentioned above and includes aspects such as the plasticity and plasticity development and internal force redistribution. These aspects have not been reported in more detail. In addition to the common research on ultimate bearing capacity and deformation capacity of composite beams with web openings, this study considers the influence of opening locations on the plasticity performance, vertical shear distribution and bending moment redistribution of continuous composite beams.
