Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Estimating Arias Intensity From Response Spectrum

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...

Longitudinal combined seismic mitigation systems and optimal control for long span triple-tower suspension bridges

Advances in Bridge Engineering
Compared with the two-tower suspension bridge, the seismic response of the middle tower is crucial for the seismic design of triple-tower suspension bridges. A finite element model was developed for a suspension bridge.

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Machine Learning‐Driven Classification and Production Capacity Prediction of Tight Sandstone Reservoirs: A Case Study of the Taiyuan Formation, Ordos Basin

Energy Science &Engineering, EarlyView.
On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...
