Effect of shear span-to-depth ratio on shear strength components of RC beams
Engineering Structures, 2018Abstract The additive model of shear strength of reinforced concrete (RC) members, i.e. shear strength (V) is equal to the sum of the contribution from concrete (Vc) and that from transverse reinforcement (Vs), has been widely accepted in the literature and engineering practice.

Indirect Loading on Beams with Short Shear Spans
ACI Journal Proceedings, 1977A study of the effect of loading and supporting conditions on the behavior and ultimate shear strength of beams with short shear spans is presented. Previous experimental work by the authors has been extended to include a shear span-to-depth ratio = 2. The overall findings of the investigation are summarized.

Shear Behavior of Large-Scale Post-Tensioned Girders with Small Shear Span-Depth Ratio
ACI Structural Journal, 2010Although there have been several studies on the shear behavior of prestressed concrete beams, these generally focused on shear capacity rather than shear deformation. The present study investigated the shear deformation of large-scale reinforced I-shaped girders and post-tensioned prestressed concrete girders with a small shear span-depth ratio of 2.5.

Experiments on thin airfoils spanning a transonic shear flow
1976A wind tunnel was built at the California Institute of Technology to provide two uniform coflowing streams at Mach numbers of 0.6 and l.4 with a plane mixing layer in between. Preliminary studies were made of this free shear layer, indicating a region of self-similar behavior and general agreement in growth rate with previous studies.

Experimental Investigation of Trapezoidal Profile Sheeting under Varying Shear Spans
Applied Mechanics and Materials, 2016Composite construction method has been mainly popular due to its faster, lighter and economical methods in high rise buildings. Composite deck slab consisting of two different components, concrete being good in compression placed at the upper portion and the cold form profiled sheeting being good in resistance to tension is placed at the bottom of the ...

Deep Beam Behavior Affected by Length and Shear Span variations,”
ACI Journal Proceedings, 1971THE RESULTS OF AN INVESTIGATION OF 12 REINFORCED CONCRETE DEEP BEAMS ARE DESCRIBED IN WHICH THE VARIABLES A/D AND L/D ARE SYSTEMATICALLY VARIED AND OTHER MAJOR VARIABLES ARE KEPT CONSTANT. THE EFFECTS OF CHANGES IN A/D AND L/D ON FAILURE, DIAGONAL CRACKING, STEEL STRAINS AT THE SUPPORTS, MAXIMUM CRACK WIDTHS, AND MIDSPAN DEFLECTIONS ARE SUMMARIZED ...

SEISMIC PERFORMANCE OF PRESTRESSED CONCRETE COMPOSITE SHEAR WALL WITH MEDIUM SHEAR SPAN RATIO
A new type of prestressed concrete composite shear wall is put forward. This shear wall consists of double precast concrete slabs with steel trusses and prestressed steel and concrete-filled between the two slabs. The cracking resistance of precast slab is improved due to the prestressed steel and the thickness of this precast slab was reduced to 35 mm.openaire +1 more source
Punching Shear Behavior of Slabs With Varying Span-Depth Ratios
ACI Structural Journal, 1990The results of an experimental investigation of the punching shesr strength of reinforced concrete slabs with varying span-depth ratios are summarized. Ten axisymmetric slabs were tested. The slab thickness was kept constant while the support diameter was varied to produce different span-depth ratios.
