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...
Steel and concrete composite building structures an economical approach
Costa, Catarina; Costa-Neves, Luís F.; Lima, Luciano R. O. deSteel and concrete composite structures are becoming a more and more common solution for buildings, since its structural efficiency and fast erection methods make its use economically competitive. A parametric study dealing with steel and concrete composite structures for typical office buildings braced horizontally and with regularly spaced columns is presented. The varying parameters are the type of column la...
Influence of chord axial load on the stiffness and resistance of welded “t” joi...
Matos, Rui M. M. P. de; Costa-Neves, Luís F.; Lima, Luciano R. O. deThe use of structural hollow sections is currently growing very fast, being of major importance an accuracy assessment of the analytical approaches available to these elements, namely their connections. These elements are mainly used in truss structures where the connected members are submitted to important axial forces. In this paper some results concerning Square Hollow Section (SHS) welded “T” joints will be...
