Abstract

The objective of this study is to analyze the differences in structural behavior between conventional composite beams and shallow floor beams, using the performance of a steel beam as a reference. For this comparison, experimental data and numerical simulation results were used for models of beams subjected to four-point bending. The tests included both conventional composite beams and shallow floor beams, both utilizing hollow core slabs, as well as numerical simulations of the isolated steel beam. It is important to note that in all models, the same steel profile was used with the same span between supports. The comparisons focused on the initial stiffness and ultimate strength of the beams. The results showed that the conventional composite beam exhibited the best performance, being the most rigid and achieving the highest ultimate load. Regarding the shallow floor beam, it was observed that its behavior, in terms of both stiffness and strength, also surpassed that of the isolated steel beam, highlighting the significant contribution of the hollow core slab to the improvement of structural performance.

Patricia Tavares de Souza Spavier, Universidade de São Paulo - USP

Patricia Tavares de Souza Spávier is a civil engineer who graduated from São Paulo State University Júlio de Mesquita Filho (UNESP) in 2013. With a strong interest in structural engineering, she continued her academic training at the School of Engineering of São Carlos at the University of São Paulo (USP), where she obtained a master's degree in Civil Engineering with an emphasis on Structural Engineering in 2016. Her master's thesis, titled "Theoretical and Experimental Analysis of Shallow Composite Floors Composed of Steel Beams and Hollow-Core Concrete Slabs," explored the behavior of composite systems, focusing on the interaction with precast concrete elements.

Continuing her academic journey, she completed her Ph.D. in Civil Engineering, also at USP, in 2020. During her doctoral studies, she developed a dissertation titled "Experimental and Numerical Analysis of the Connection between Partially Encased Composite Columns and Steel Beams without Interruption of the Encasing Concrete," in which she investigated the interactions between structural components, contributing to the advancement of knowledge in the field of composite structures.
