EARTHQUAKE ANALYSIS OF THE LOWER SAN FERNANDO DAM USING ELASTIC, EQUIVALENT LINEAR AND BOUNDING SURFACE PLASTICITY MODELS

Journal of Engineering, 2003
Uncoupled behaviour of a dam undd, earthquake loading is investigated. Three constitutive models are used:. The linear-elastic model where soil properties; shear modulus and damping ratio are strains ar d cycle independent.-The equivalent linear model ...

Reliability Analysis of a Filtering Reducer under the Discrete Space Environmental Shocks

Advances in Mechanical Engineering, 2014
Dynamic reliability analysis of a filtering reducer is performed by accounting for discrete shocks from the space environment. Gears are considered as the lumped mass and meanwhile the meshing between different gears is equivalent to a dynamic system ...

Dynamic Behavior and Force Analysis of the Full Vehicle Model using Newmark Average Acceleration Method

, 2020
In this study, the dynamic interaction between road and vehicle is modeled. For this purpose, a full vehicle model with eight degrees of freedom is considered. The equations of motion of the whole system are derived by the D'Alambert method and numerical

Construction of a Joint Newmark–Runout Model for Seismic Landslide Risk Identification: A Case Study in the Eastern Tibetan Plateau

Land
The key to seismic landslide risk identification resides in the accurate evaluation of seismic landslide hazards. The traditional evaluation models for seismic landslide hazard seldom consider the landslide dynamic runout process, leading to an ...

A physics-based integrated sem-newmark model for regional-scale coseismic landslide assessment

, 2019
Coseismic landslides are one of the most catastrophic effects of earthquakes. Realistic prediction of coseismic landslides is crucial for the design of key infrastructure and to protect human lives in seismically active regions.

Modeling and Monitoring of the Dynamic Response of Railroad Bridges using Wireless Smart Sensors [PDF]

, 2015
Railroad bridges form an integral part of railway infrastructure in the USA, carrying approximately 40 % of the ton-miles of freight. The US Department of Transportation (DOT) forecasts current rail tonnage to increase up to 88 % by 2035.
