TL;DR: In this article, the role of polypropylene fibers (PP) at elevated temperature in self-compacting cement paste samples was investigated by backscattering electron microscopy (BSE) and mercury intrusion porosimetry (MIP).

TL;DR: In this paper, full-scale tests are conducted to determine the ultimate bearing capacity of continuously jointed segmental tunnel linings, considering changes of the surrounding environment, and the design of tested linings and loading schemes are described.

TL;DR: In this article, a comprehensive methodology and framework for aggressive inspection and condition based predictive maintenance of a shield tunnel consisting of prefabricated lining rings is presented, which consists of six components: maintenance purposes, data, modeling and simulation, documentation, managerial schedule, and inspection/maintenance behaviors.

TL;DR: In this paper, the structural bearing capacity of stagger joint assembled shield tunnel linings is investigated in an unloading situation, which combines engineering practices relevant to the current urban metro with circumferential disturbances.

TL;DR: In this paper, a stochastic multiscale computational model for predicting the mechanical properties of fiber reinforced concrete (FRC), subjected to tensile loading, is proposed, which involves the microscale, the mesoscale and the macroscale.
