Analysis of the Effect of Passive Vibration Control on Planar Truss Structures Subjected to Resonant Loading

Resumo

With scientific advances in Civil Engineering, construction processes have significantly evolved in terms of materials, methods, and technologies, enabling the execution of increasingly slender structures. In this context, trusses have stood out due to their lightness and high load-bearing capacity, being widely used in various engineering applications. However, such structures are often subjected not only to static loads but also to dynamic actions, such as vibrations induced by resonant loading, which can compromise their stability, functionality, and service life. In light of this, the present project proposes the development of a computational algorithm, using the Java programming language, capable of analyzing the effects of applying passive vibration control in planar truss structures subjected to dynamic excitations. The algorithm was integrated into Lacker, a software still under development by the research group of the Federal Institute of Maranhão, which aims to provide a suitable computational environment, especially regarding input structure and data processing, for dynamic structural analysis and the implementation of a new passive control module. The algorithm’s functional validation was carried out through comparison with consolidated results found in the literature, based on studies recognized in the field addressed by this study.
