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 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 ...

This research comprehends a study of the analysis procedures of the global stability in precast concrete structures, considering the effect of the semi-rigid connections. A Look over in the standards and directives of the ...

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 ...

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 reinforced concrete precast beams is strongly influenced by the flexural stiffness of its beam-column connections, wherein there is interdependence between the nonlinearity of the moment-curvature relationship ...
