EFFECT OF SHEAR SPAN RATIO ON THE FRACTURE OF DEEP BEAMS
Doboku Gakkai Ronbunshuu E, 2006 せん断スパン比(以下，a/d)が小さく，せん断補強筋を有するディープビーム部材を対象に，a/d，せん断補強筋比，有効高さをパラメータとして，単純梁を用いた鉛直載荷実験を行い，せん断抵抗に関する検討を行った．その結果，a/d≦1.0とa/d=1.5では終局時の破壊の形態が異なることが，デジタルカメラやひずみの計測を詳細に行うことにより明らかとなり，a/d≦1.0のせん断破壊では，圧縮力が主体となるためせん断補強筋はほとんど効果を発揮しないが，a/d=1.5ではひび割れ幅の抑制効果があることからせん断補強筋が十分に効果を発揮することが分かった．また，本研究におけるせん断耐力評価式は実験値を概ね評価できることが分かった．

Theoretical Study of Shear Wrinkles in Web Span
JAPAN TAPPI JOURNAL, 2011 抄紙機や輪転機などの連続走行紙（巻取紙）の搬送において，紙要因によるシワのトラブルはその発生メカニズムが判然としないため対応に苦慮する場合が多い。そこで，シワがローラに乗り上げて折ジワにつながる前段階としての剪断ジワが，紙要因で発生する条件について，紙の走行性の観点からFEMを用いて理論的な考察を行った。その結果，配向角の傾きやテンションのプロファイルといった紙由来の要因により，走行紙の横移動を生じる可能性があることが判明した。これは，張力が負荷されることによって紙が駆動ローラ上で剪断変形し，その状態のまま摩擦搬送されることによって起こると考えられる。さらに，紙の張力と横移動によって生じた剪断ジワが，ローラ上に乗り上げて折ジワへと成長する過程を解析する手法についても検討を行った ...

Seismic axial collapse of short shear span reinforced concrete shear walls
, 2020 This thesis addresses the seismic behaviour investigation of reinforced concrete (RC) shear walls in a low-to-moderate seismicity region which faces its own class of challenges inherited from non-seismic construction practice. In the current global norm of shear wall research in high seismicity region, discussions on slender walls in tall buildings and
