Continous beam model subjected to dynamic load in design and construction of building structures

This paper study about caculating floor plate and formwork floor plate are modeled as continuous beams subjected to dynamic loads in the textbooks of reinforcement structure, steel structure and construction engineering. Proposed, compared and calculated some beams subjected to dynamic loads with frequency ω, beam with other connecting boundary, beam with cracked etc to determine their displacements and inner forces. There are some eigensolutions which have been showed that, when have cracked the frequency always be smaller than have not. The results of these displacements an inner forces following considering models are more reality than models in common use.
