Basic Design Requirements for Structures Subjected to Dynamic Action

Abstract

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).
