ABSTRACT The main concern of this paper is remark to engineering graduating students how the lack of basic applied concepts of structural mechanics may lead usual structures to collapse. First of all, a location of the theme on technical literature is performed and fundamental tools are summarized, such as Newton's laws and conditions of equilibrium based on geometrical considerations. Real cases of collapses had been collected in news published in the Internet where the equilibrium failed because primary concepts were not respected. Conclusions are presented in a way of helping the future engineers to be aware about the responsibility involved in the design and preventive maintenance of structures as well as the understanding of the aspects of conception, essential to a successful career.

    ABSTRACT: The main concern of this paper is to show, both geometrically and mathematically, how to check if a three-dimensional truss (or space structure, SS) is always kinematically stable (geometrically determinate), irrespective of the number of support bars. Investigations were made on the so-called square-on-square double-layer grid (MAK81), but different layouts may be similarly analysed as well. A few of such structures have collapsed recently in Brazil, and the second and third authors have been investigating the causes of those collapses. On the other hand, the first author has been more concerned about the conceptual model of truss designing and it seems that one of the reasons for those collapses could be related to this paper subject.
