Design of pre-cast two-column bents using strut-and-tie models and nonlinear fi...
Carvalho, Lucas; Pimentel, Mário; Arêde, António; Pouca, Nelson Vila; Delgado, Pedro; Pinto, José RuiThe collapse of the Cypress Street Viaduct during the 1989 Loma Prieta earthquake raised awareness to the seismic design and detailing of the connections between cap beams and columns. Current standards require a considerable amount of transverse reinforcement inside the joints, leading to reinforcement congestion and constructability problems. Moreover, some design rules are rather unclear and the link to the ...
Numerical modelling and strut-and-tie concepts for seismic design and assessmen...
Carvalho, Lucas; Pimentel, Mário; Delgado, Pedro; Arêde, António; Pouca, Nelson Vila; Pinto, José RuiPrecast structures are more common in zones not affected by earthquakes or affected by low - to moderate-intensity earthquakes; the application of precast structures in zones of higher seismic intensity is unusual due to the seismic performance uncertainty of these structures. Concerning precast bridges, special attention needs to be paid on the column to cap-beam connections, as well as the methods to anchor t...
Risk Factors for Delayed Discharge Due to Social Factors: A Retrospective Study
Martins, Miguel; Mesquita, António; Carvalho, Lucas; Martins, Francisca; Silva, Mariana; Leitão, Helena; Nunes, MiguelIntroduction: The hospital setting faces a rate of bed occupation by patients whose discharge is limited by other factors apart from clinical needs. This urges the need for an early identification of the patients at risk of delayed discharge due to social factors in order to reduce expenses and to add value that converts itself into the patient health. The aim of this study was to identify the demographic and c...
