NEWMARK ALGORITHM FOR DYNAMIC ANALYSIS WITH MAXWELL CHAIN MODEL

Acta Polytechnica, 2021
This paper investigates a time-stepping procedure of the Newmark type for dynamic analyses of viscoelastic structures characterized by a generalized Maxwell model. We depart from a scheme developed for a three-parameter model by Hatada et al.

Co-seismic landslide hazard assessment of Uttarakhand state (India) based on the modified Newmark model

Journal of Asian Earth Sciences: X, 2022
Co-seismic landslides are the most dangerous geological hazards in seismically active mountainous regions. These landslides cause damage to roads, drainage pipelines, buildings, agriculture, and loss of human lives.

Predicting seismic landslide hazard in the Batang fault zone of the Qinghai-Tibet Plateau

Shuiwen dizhi gongcheng dizhi, 2021
The Batang fault on the eastern Qinghai-Tibet Plateau has strong activity since the Holocene, where the geomorphology and geological structure is complex, and the historical earthquakes occurred frequently, which induced abundant landslides. For the long-

Vibration Response Evaluation under Shock-Type Loading with Emphasis on Finite Element Model Updating

Shock and Vibration, 2020
In some cases, impulse- or shock-type excitations as the dynamic loading are inevitable, and obtaining proper response with the well-known numerical methods is not easy. This paper focuses on dynamic response estimation against short-time loading with an
