A System for the Optimal Design of Composite Floor Systems Composed of Tubular Trusses

Resumo

The use of composite steel and concrete systems has grown significantly over the past decades, due to their fast construction process, as they reduce the need for formwork and optimize steel and concrete usage. These systems are usually designed with solid-web beams; however, other competitive alternatives are available, such as using tubular trusses. This study aims to present a system for the optimal design of composite floor systems composed of tubular lattice girders, with or without concrete infill. The program was developed in the MATLAB platform using the AppDesigner tool. An interactive and intuitive interface was created to simulate different floor configurations, considering various truss topologies, load cases, and slab design criteria. As a result, floor systems will be optimized using optimization algorithms, providing the optimal topologies for the analyzed floor systems.
