Non-linear dynamic analysis of stayed steel columns
Araujo, Ricardo R. de; Silva, José G. S. da; Vellasco, Pedro C. G. da S.; Andrade, Sebastião A. L. de; Lima, Luciano R. O. deThis work describes non-linear finite element simulations made on stayed system subjected to sudden impact loads. The study aimed to determine the influence of the prestress forces magnitude and its response with and without damping effects. Various cases where the load magnitude varied from 10% up to 100% of the stayed column load bearing capacity were investigated. The performed analyses enabled an evaluation...
A parametric analisys of composite beams with t-perfobond shear connectors
Vianna, Juliana da C.; Andrade, Sebastião A. L. de; Vellasco, Pedro C. G. da S.; Neves, Luís F. da C.This paper presents the design and push-out test results of T-Perfobond connectors. The shear connectors were made with two different geometries by varying the connector flange thickness. The TPerfobond connectors presented two web holes and were immersed into 120mm thick concrete slabs. Reinforcing steel bars were used inside the web holes to increase its structural performance. A numerical study was also made...
