  • Assessment of Seismic Behavior of an RC Precast Building
    Publication . Vitorino, Hugo; Batalha, Nadia; Sousa, Romain; Fernandes, Paulo; Varum, Humberto; Rodrigues, Hugo
    Past earthquakes brought attention to the poor performance of precast reinforced concrete structures. One of the problems observed in those structures is related to the beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is an important aspect that should be studied. The numerical analyses developed allowed the study of the effect that different connection properties have on the frequencies of vibration, members drifts, and seismic coefficients. The connection properties were modeled through a macro-element that considers the friction (between concrete–concrete and concrete–neoprene) and the steel dowels. The results showed that the friction between concrete elements and the consideration of the neoprene in the connection has a small impact on the drifts demands in the columns and seismic coefficient of the analyzed structure; on the other hand, the effect of the steel dowel on the drift demand and seismic coefficient is significant. The comparison of the models with different properties and connections allowed a better understanding of the factors with a higher impact on the results.

  • Introduction
    Publication . Gaspar, Florindo; Rodrigues, Hugo; Fernandes, Paulo; Mateus, Artur; Artur Mateus
    This first Conference on Automation and Innovation in Construction (CIA2019) aimed to be a reference forum for scientific discussion of technological developments in the field of innovation on automation in the construction industry. The conference started with several examples of BIM applications to different uses in the construction sector, from design to rehabilitation and maintenance, examples of robotics applied to constructions inspection have been shown, new methodologies and approaches to support decisions or the use of augmented reality and additive manufacturing in construction have been presented, namely, an example of application to space construction.
