Numerical Approaches

In a space frame, there exist in- and out-of-plane bending, axial, and torsional vibrations. The analysis of complex vibrations in such structures has relied mostly on numerical approaches. In this study, a wave-based analytical approach is applied to obtain solutions to vibrations in space frames. Both free and forced wave vibration responses are obtained, with bending vibrations modeled using the Timoshenko theory. A two-story steel space frame is built to validate the analytical results, and good agreements have been reached between the analytical and experimental studies. The effect of torsional rigidity adjustment on the accuracy of predicted vibrational responses in structures involving rotationally nonsymmetric cross sections is also examined.

This study investigates the dynamic performance of a large-span suspended steel space frame-glass composite floor (SSSF-GCF). Both the ambient vibration and the human-induced vibration of the floor were experimentally measured to identify vertical dynamic characteristics and evaluate vibration serviceability of the floor. Although vertical dynamic characteristics of the floor based on the global simplified finite element (FE) model of the structure agree well with those identified via experimental modal analysis, the global simplified FE model significantly underestimates vertical vibration amplitudes of the floor due to the coupled effect between two layers. Accordingly, an equivalent local FE model of the floor system was proposed and updated via adjusting the vertical stiffness of the interstory hanging pillars. It is shown that the equivalent local FE model can well predict both the dynamic characteristics and human-induced vibration response of the floor. Finally, the effect of the damping ratio on the acceleration response of the floor was numerically demonstrated with the verified local FE model.

RESUMENEn ocasiones se producen patologías que aun siendo singulares como es el caso que se presenta, ya se han producido anteriormente, y pese a ello, no se ha sabido transmitir las enseñanzas de esas tipologías de daños, y vuelven a repetirse. Se quiere hacer resaltar que los estudios de daños han de servir para implementar en la normativa los requerimientos necesarios para alejarnos de situaciones de riesgo.Se presenta el colapso de una cubierta espacial metálica con barras de acero inoxidable de sección circular con uniones simplemente ensambladas en sus extremos en una barra que hace las veces de nudo.Palabras clave: Pandeo local y global; cubierta espacial metálica; siniestros; patologías recurrentes.ABSTRACTNon common pathologies can be presented occasionally and recurrently as in this case study. This happens especially because of a lack of knowledge transmission. Most damage studies must serve to prepare standards and documents to avoid risk situations.It is presented the collapse of a space frame roof with circular stainless steel bars with joints of stainless steel which threads the extremes of the space frame bars.Key words: Local and global; buckling space frame roof; disasters; repeated pathology.
