This research had the purpose of evaluating the relationship between the physical and mechanical properties of Cambará wood extracted from three distinct sites: Vera, Mucajaí and south of Rondônia. The possibility of ...

The construction sector stands out as responsible for the emission by third of the total greenhouse gases emitted by mankind. The processes of extraction and manufacture of the raw materials, necessary to obtain the concrete, ...

Nowadays the manufacture of I beams of bridges with section of multiple beams is made in the place using the preforming. However if these beams were prefabricated they could have more quality in executive aspects, in ...

The present work carried out a theoretical-experimental study of a transverse reinforcement arrangement for slabs with lattice-reinforced joists. The objective of the research was to investigate both its structural behavior ...

In this dissetation exploratory models are used to examine the behavior of semi - rigid pillar - beam connections with shear key. This type of connection is ordinary in Brazil prefabricated concrete structures. Thus, the ...

The steel-concrete composite columns are characterized by the combination of steel profiles and structural concrete to form a single, tough section. Among the composite columns, the one of the filled type stands out, ...

Self-compacting concrete (SCC) must simultaneously exhibit high fluidity, cohesion and absence of segregation. However, the maintenance of these properties in the fresh state requires a greater consumption of binders and ...

This work aims to document the production process and characteristics of the new Brazilian prestressing steel CP-210 RB, as well as evaluating its use viability and to indicate design guidelines for the application in the ...

The calculation of flexible or rigid mat foundation is difficult to perform because it is a matter of analyzing a plate resting on the ground, subjected to the external actions and the reactions of the soil. Following a ...

This work is an unpublished survey on the analysis of the use of a prestressed concrete constructional system with greased corbels in smooth slabs in multi - storey buildings in Brazil, according to the new norm NBR 6118: ...
