This work is an unpublished survey on the analysis of the use of a prestressed concrete constructional system with greased corbels in smooth slabs in multi - storey buildings in Brazil,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

Considered as a modern method of construction (Modern Methods of Construction, or simply MMC), the hybrid construction system presents several advantages over other systems. It combines the benefits of precast construction ...

The use of prestressed hollow core slabs has increased significantly and, consequently various productive methods have emerged. These methods do not employ machinery such as extruders or slip former machine. In this research, ...

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 ...

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 ...

There is no consensus in the estimation of the number of native species coming from the Amazon Forest, and it is necessary to study the technological properties of tropical wood species for the rational use of this ...

The use of waste in the construction industry is gaining more space in the scientific universe and a very discussed point is the real durability and possibility of using the materials developed. The real contribution of ...

The prestressed hollow core slabs present uncertainties regarding the evaluation of the resistance to the resistant shear force. This is because several parameters influence the shear-resistant mechanism of prestressed ...

The aim of this paper was the validation of the monolithic equivalence applied to precast columns with grouted splice sleeve connections, wherein spliced precast prototypes have been compared with continuous monolithic ...
