Structural Behavior of Composite Floor System Using Cold-Formed Thin-Walled C Steel Channel Embedded Foam Concrete

In this paper, a new composite floor system using cold-formed thin-walled C steel channel embedment and foam concrete slab is developed. This type of features lightweight, high fire-resistant, anti-corrosion features, can be used for multi-story buildings, providing promising alternative the construction market. Two four-point bending tests were carried out to investigate flexural capacity failure modes slab. Based on test results, nonlinear finite element model was developed general software package ABAQUS. The validated results. Using model, parametric studies performed study key parameters affecting structural behavior system. Different such as density concrete, grade embedment, spacing investigated. Their contributions overall moment their effect discovered. experimental results FE design formulas ultimate slabs also which accurately predict capacity.
