Advanced Parametric Modelling of Pyramidal Trusses

Resumo

Trusses are an affordable and easy solution for engineers, especially when spanning large distances. It is notorious that several aspects of trusses influence their behavior. By accounting for material and geometric non-linearities, this study examines the behavior of pyramid trusses under vertical load. Practical applications make these structures valuable as either a primary or secondary component. This study looks at how elastic and inelastic
stability of pyramidal trusses are influenced by factors like focus height, base radius and number of bars. Therefore, it will be possible to identify the ideal stability and strength configurations for pyramidal trusses. The advanced nonlinear analyzes intend to use results from the literature or obtained via other softwares in the calibration of the proposed numerical models. It will be possible to perceive under what conditions the pyramidal truss presents gain and loss of rigidity, indicating alternatives for designers that envisage such structure shape.
