Prestressed precast concrete hollow core slabs used as floor is becoming increasingly current in Brazil. Being quickly assembled and with competitive price, this solution provides an efficient section given by the reduction ...

The floors consist of hollow core slabs are being increasingly used in Brazil, because it can overcome large spans, have a low self-weight, allow fast assembly, require no shoring in many situations and are more economical ...

This work shows a calculation sequence to determine and detail the longitudinal and transverse reinforcement of prestesses beams with pre-composed section. All procedures are done in a way that meets all the requirements ...

The increasing of using precast concrete panels, lack of standardization, lack of studies on precast concrete panels and its connections devices on Brazil, has led to the need of manual and design criteria of precast ...

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 ...

The use of prefabricated elements has become increasing in Brazil, This paper describes the study and the procedures for construction and erection of a building system works on a pavement. Within the concept of technological ...

This work presents design and executive procedures for pre-cast slabs with unidirectional ribs, which are one of the most used construction elements for small buildings in the country, discussing aspects related to ...

This research deals with the experimental investigation of time dependent deformations in partially precast floors with composite beam-and-block floor systems made with reinforced concrete lattice joist through the measurement ...

The behaviour of prestressed precast beams is directly affected by the rotational stiffness of the end connections. Although the prestressed beam presents a linear behaviour in service, the effective behaviour of the precast ...

The present research deals with the study of continuity in slab-beam-column connections in precast concrete structures, wherein an experimental investigation about the contribution of longitudinal reinforced bars, passing ...
