Prediction model to determine natural frequency for integral abutment bridge: a simplified method [PDF]
, 2015 All bridges can be resonated with certain frequencies known as modal frequency. Different bridges will have their own natural frequencies depending on their types, parameters and configurations.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Reinforced concrete pier walls designed before the 1970s often incorporate lap splice in potential plastic‐hinge regions. Previous experimental tests indicate that most of pier walls experienced post‐yield lap splice failure, necessitating a modeling approach that captures not only lap splice strength but also deformation capacity.

Three‐Dimensional Analytical Model of a Free‐Standing Square Rocking Column
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT A three‐dimensional analytical two‐degree‐of‐freedom (2DOF) model is developed to describe the bounded rocking response of free‐standing rigid square columns subjected to bidirectional seismic excitation. The formulation extends Housner's classical planar theory by deriving the full three‐dimensional equations of motion for a column ...

Energy Science &Engineering, EarlyView.With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance

Energy Science &Engineering, EarlyView.This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

Effect of creep on time-dependent behaviour of prestressed concrete integral abutment bridge [PDF]
, 2014 A parametric study was conducted to assess effect of creep on long term behaviour of prestressed concrete Integral Abutment Bridge (IAB). Varying backfill soil types were provided behind the bridge abutment and the interaction was modelled using linear ...
