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 ...

This research deals with the behaviour of grouted dowels used in beam-to-column connections in precast concrete structures. The research focuses primarily on the theoretical and experimental analysis of the resistance ...

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 ...

In this paper, the results of the proposed ductile precast concrete end-diaphragm beams for the transverse seismic resistance and protection of the substructure of slab-on-girder concrete bridges, tested at the facilities ...

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 ...

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 present work aims to investigate the web post buckling resistance of composite cellular beams. For this task, geometrical and physical non-linear analyses are developed in the ABAQUS® software. The computational model ...

The big surge in use of systems for flat slabs gave up the search for freedom in the definition and organization of architectural interior spaces in buildings. The design and construction of buildings on flat slabs, which ...

Although an increasing demand on precast concrete structures exists, there is a lack of tools for the safe design of precast connections in many situations. This research focuses on the study of semi-rigid beam-column ...
