Basic Design Requirements for Structures Subjected to Dynamic Action

Thiago Porto, Beatriz Mendoça, Lucas S. Carvalho


The existence of industrial equipment such as crushers, grinders, compressors, sieve shaker and dryer, generate vibrations in structures. As a result, displacements, velocities and accelerations appear and cause discomfort during normal human activities, operational and / or operational problems in mechanical equipment. It is, therefore, a limit state, with the definition of permissible limits in the structure to displacement, velocity and acceleration. These values are recommended by equipment manufacturers and / or international standards. This work establishes the basic requirements that must be known in the design of concrete structures subjected to dynamic actions derived from industrial equipment. In this paper, a ball mill and a dryer are discussed as case studies. For the numerical modeling of the proposed problem, was used the Finite Element Method (FEM).
