Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Seismic Behavior of Precast Prestressed Concrete Frame with Hinge-Relocated Mortise–Tenon Connections

Buildings
To satisfy the easy-construction demands of precast concrete (PCa) frames after an earthquake, a PCa frame with mortise–tenon (MT) connections is proposed in this paper.

Geophysical implications from relocations of Tibetan Earthquakes; Hot lithosphere

Geophysical Research Letters, 1991
ISC locations for earthquakes beneath Tibet indicate a random distribution of events down to a depth of about 50 km. This distribution would be expected from a relatively cool crust which would allow the seismo‐genic zone to extend to such depths. A detailed investigation of the Tibetan earthquakes, with magnitude greater than 5.5 from 1964 to 1986 ...

Improved procedure for determining the ductility of buildings under seismic loads [PDF]

, 2018
Displacement ductility is a parameter that characterizes the seismic response of structures. Moreover, displacement ductility can be used in order to determine whether a structural design, performed according to a specific seismic code or not, may ...
