Advances in Civil Engineering, 2022 Most of the prediction models for the shear capacity of FRP bar reinforced concrete beams without web reinforcement in current codes are reported to be conservative and do not consider the effect of span-to-depth ratio.

Experimental study on seismic behavior of reinforced concrete shear walls with low shear span ratio
Journal of Building Engineering, 2022 Abstract Shear span ratio (SSR) is a key factor affecting the structural and seismic behavior of shear walls. Existing experimental studies on the seismic behavior of shear walls with SSR less than 1.0 are limited. In order to study the seismic behavior of squat reinforced concrete (RC) shear walls, 16 specimens (of which four specimens were ...

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 ...

Shear resistance of SFRSCC short-span beams without transversal reinforcements [PDF]
Composite Structures, 2016 Abstract Corrosion of steel reinforcements, especially stirrups, is considered as one of the most common reasons that shorten the service life of the reinforced concrete structures. This study aims to replace the stirrups of the beams by means of a tailor made steel fiber reinforced self-compacting concrete (SFRSCC).

Shear Performance of Horizontal Joints in Short Precast Concrete Columns with Sleeve Grouted Connections under Cyclic Loading. [PDF]
PLoS ONE, 2016 In this study, two short precast concrete columns and two cast-in-situ concrete columns were tested under cyclic loads. It was shown that the sleeve grouted connection was equivalent to the cast-in-situ connections for short columns when the axial ...

Shear performance of poplar LVL beams with a hole in bending-shear spans
StructuresYes To investigate the shear performance of poplar laminated veneer lumber (LVL) beams with holes in bending-shear spans, six specimens were designed and tested by four-point bending tests. Among these, five specimens were provided with a single hole of varying diameter-to-height ratio in the bending-shear span and two of these beams were also ...
