Structural Effects of Vertical Non‐Skeletal Elements (NSEs) With Rocking Mechanisms

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper introduces the structural effects provided by vertical non‐skeletal elements (NSEs), such as claddings and partitions, with vertical slotted holes at their supports to enable rocking as the frame undergoes significant lateral deformation.

Numerical Simulations of 5‐Story Building Using Wood Light‐Frame Shear Walls and Post‐Tensioned Cross‐Laminated Timber Rocking Wall Dual Systems

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study explores the seismic performance of a five‐story prototype building using different configurations of a dual lateral force‐resisting system (LFRS) combining post‐tensioned cross‐laminated timber rocking walls (PT‐CLT‐RW) with conventional wood light‐frame shear walls (LiFS).

Deteriorated Hysteresis Behavior of Reinforced Concrete Bridge Columns With Lap‐Spliced Circular Hoop Reinforcement

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Five lap‐spliced circular hoop (CH) concrete bridge columns, designed in accordance with the current Japanese bridge design code and Taiwan bridge design practice, were tested in this study to investigate the effects of longitudinal reinforcement and aspect ratios on deteriorated hysteresis behavior.

A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

open access: yesEnergy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Characteristics Analysis and Stage Division of Class Ⅰ Gas Hydrate Deposit Developed by Vertical Well and Depressurization Based on Numerical Analysis

open access: yesEnergy Science &Engineering, EarlyView.
The production process can be divided into two stages according to the relationship between the gas production rate and the decomposition gas rate. The ratio of cumulative decomposition gas to cumulative gas production can be used to evaluate the contribution of the gas hydrate layer.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Characteristics of Gravity Flow Deposits in the Benin Basin (Benin) and Implications for Oil and Gas Exploration

open access: yesGeological Journal, EarlyView.
This study reveals that the underexplored Benin Basin features a narrow shelf and steep slope, which promoted the development of multi‐phase, stacked channel‐lobe complexes. These gravity flow deposits, further enhanced by bottom current reworking, reveal a significant undiscovered Upper Cretaceous stratigraphic play with considerable petroleum ...
