A Numerical Study of Wave Propagation and Cracking Processes in Rock-Like Material under Seismic Loading Based on the Bonded-Particle Model Approach

open access: yesEngineering, 2022
An earthquake is usually followed by a considerable number of aftershocks that play a significant role in earthquake-induced landslides. During the aftershock, the cracking process in rocks becomes more complex because of the formation of faults.

Bidirectional Loading History for Seismic Testing of 3D Frame Joints

open access: yesCivilEng, 2021
Beam-column-joints (BCJ) in reinforced concrete (RC) frames are known to be critical against seismic actions. Hence, several researchers have conducted related investigations.

Effect of Seismic Loading on Variation of Pore Water Pressure During Pile Pull-Out Tests in Sandy Soils

open access: yesJournal of Engineering, 2021
Experimental model was done for pile model of L / D = 25 installed into a laminar shear box contains different saturation soil densities (loose and dense sand) to evaluate the variation of pore water pressure before and after apply seismic loading.

Experimental study on the influence of seismic subsidence of loess under bidirectional loading modes

open access: yesEarthquake Research Advances, 2021
Water content, dry density, void ratio, depth of soil layer, and seismic loading may all exert influence on the seismic subsidence of loess. Many scholars have carried out seismic subsidence tests of loess to simulate the stress on soil using ...

A Review-Behavior of Reinforced Concrete Exterior Beam-Column Connections under Cyclic Loading [PDF]

open access: yesE3S Web of Conferences, 2021
In many seismically active regions worldwide, massive reinforced concrete (RC) structures built before the 1970s existed. These older RC buildings, in countries having seismic history, were designed for gravity loads only.

Proposal of fatigue assessment method for piping under seismic loading (About the use of effective strain range for loading sequence effect)

open access: yesNihon Kikai Gakkai ronbunshu, 2021
A loading sequence effect on fatigue life was investigated for piping under seismic loading. A fatigue assessment method which can consider the loading sequence effect conservatively was proposed using the effective strain range.
