Foreshocks, Aftershocks and an Earthquake Swarm Detected by the Micro-earthquake Observation

Foreshocks, Aftershocks and an Earthquake Swarm Detected by the Micro-earthquake Observation
application/pdf 昭和38年2月9日,上高地付近に小区域地震(気象庁発行の地震速報によればM=5.8)が起こつた.たまたま震央より約20kmの距離にある黒部第四ダムにおいて,HES 1-0.2(最高倍率50,000倍)による観測が行なわれていたので,6倍の前震,多数の余震がに測された.余震は20日頃,一応おさまつたかに見えたが,2月末から同じ地域に再び微小地震が頻発しはじめ,3月1日には1日間の発生回数が211以上に達した.マグニチュードは,本震を除いて,すべて3.5以下で典型的な微小地震群である.これらの地震群について調査を行なつたが,従来知られている,もっと大きな余震群や群発地震と比べて,ただ大きさを異にするだけで,ほぼ同じ発生様式を示していることが判つた.

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

Earthquake 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.

Experimental Study on the Lateral Response of Large‐Scale Unbonded Steel‐Mesh‐Reinforced Rubber Bearings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional unbonded elastomeric bearings (ULNRs) are cost‐effective but prone to sliding during earthquakes due to their limited shear deformability. Unbonded Steel‐Mesh‐Reinforced Rubber Bearings (USRBs) offer a solution with increased deformation capacity.

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

Earthquake 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).

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

Earthquake 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 ...
