Abstract: Interdependent infrastructure systems play a critical role in the normal operation and postdisaster emergency response in modern cities. However, they are vulnerable to earthquakes throughout their service life, resulting ...

Abstract: Substantial attention has been paid to precast structures due to their obvious advantages. While precast members connected by grouted sleeves are used in seismic regions, studies on the seismic performance of precast column ...

Abstract: Batter piles are often designed as foundation of high-rise structures to resist large lateral loads. The sizeable overturning moment of the superstructure will be transferred to the foundation so that batter piles are ...

Abstract: The depressurization method that is used to produce methane gas can increase the effective stress in hydrate-bearing sediments and induce deformation and settlement of reservoirs, which has adverse effects on safe and ...

Abstract: The epistemic uncertainty of geological condition, hydrological condition, and human factors causes the risk assessment result of metro construction to be imprecise. To reveal the epistemic uncertainty, a probabilistic ...

Abstract: Small-strain shear modulus (G0) is a fundamental property required in dynamic analyses. For sandy soils, G0 may be affected strongly by particle characteristics such as uniformity coefficient (Cu), mean particle size (d50), ...

Abstract: Two large-scale shake table experiments were conducted to study the seismic pile group–bridge soil system failure mechanisms and examine the role of soil crust in lateral spreading caused by liquefaction. Pile group–bridge ...

Abstract: A simplified mechanical model for investigating pile–pile horizontal vibration is developed by combining the Pasternak model and the Timoshenko beam theory, with the consideration of the influence of axial load at the head ...

Abstract: A significant increase in effective stress can be induced in hydrate-bearing reservoirs when the depressurization method is applied. A series of drained triaxial shear tests were performed on hydrate-bearing sediments with ...

Abstract: In this paper, we study the seismic behavior of pile group bridges in inclined liquefiable soil and reveal the failure mechanism by conducting large-scale shaking table tests. Two bridge models were supported by two ...
