Abstract

The structural robustness of reinforced concrete buildings subjected to accidental actions is nowadays a relevant research topic in the engineering community. During the years, considerable work was aimed to the evaluation of the structural robustness of monolithic reinforced concrete buildings, with scarce attention to precast concrete systems. In this context, the building may be able to withstand the gravity loads after the loss of a load-bearing element, such as a column, through the role played by the tying reinforcement, as stated in the current Eurocodes and Unified Facilities Criteria guidelines. In this paper, a simplified numerical approach is described considering both mechanical and geometrical nonlinearities for the structural robustness assessment of precast concrete buildings. Nonlinear static and dynamic responses of precast concrete frames with dry beam-to-column connections are validated against available experimental tests in the current literature. Finally, practical suggestions and future requirements are discussed aimed to improve the structural robustness of precast concrete systems
