It was evaluated the structural element by chemical characterization tests with different thickness of the concrete slab, estimating the temperature reached in each layer and, consequently, the resistance loss of the structural element. Metadata Mostrar registro completo.

However, chemical and physical changes occur in its components. Concrete, during exposure to elevated temperatures, is characterized by low thermal diffusivity and incombustibility, resulting a satisfactory performance against fire. Finally, the conclusions are provided and comments for improvements in the alvveolares of design and production of hollow core slabs, followed by suggestions for future work.

Autor Petrucelli, Natalia Savietto. The stability of the compound relates to its microstructure, so it is possible to verify the material degradation using advanced techniques of microstructural analyses. In this paper, it is described the pre-fabricated cellular slab inspection, an industrial building, which has undergone exposure to high temperatures emanating from a fire in the building ground.

Some features of this site may not work without it. So, it is briefly shown that the theory lajea to the development of calculations and verifications in the ultimate and service states, considering the bending behavior of the panels, the shear and the excessive deformation, and prestress losses that are of great importance for the final results.

Therefore, it creates a scheme to solve two numerical examples which come from a cross-section preestablished on the basis of tables published that are related to overload and long spans which the slab can achieve.

Laues this context, the use of materials tests, such as diffraction and fluorescence X-ray, proves attractive. Residual strength evaluation of hollow core slabs of reinforced concrete of an industrial building after fire.

Then compare the results obtained in the examples with the values that the tables showed and then do relevant comments. JavaScript is disabled for your browser. Resumo This work describes the procedures used in the manufacture and assembly of prestressed concrete hollow core slab systems, along with recommendations for presentation and implementation of projects in order to optimize the use of such elements and also its functionality, trying to keep the same quality and durability.
