In beams without stirrups the shear span/depth ratio was held constant at 3.6, 2.5, or 1.5 while the concrete compressive strength was varried from 3000 psi to about 15000 psi. Concrete strength was ...
Eighteen high strength full size concrete beams were tested under shear. The concretes used had nominal compressive strengths of 10,000 and 12,500 psi. The other design variables were shear span to depth ratio (a/d) and nominal shear reinforcement (vs). The shear span to depth ratio (a/...
Engineers have built structures with concrete strengths up to 11,000 psi by assuming the design rules developed for low strength concrete are also applicable to these new, higher strengths. This project investigated the suitability of the current American Concrete Institute shear design provisions for...

The contribution of the HPFRC material to wall shear strength was estimated to be in the order of 4.5√(f_c^' ) (psi). 展开 关键词: Civil engineering Shear strength and drift capacity of reinforced concrete and high-performance fiber reinforced concrete low-rise walls subjected to ...
In this study, a microcapsule-based self-healing sand was developed, and its performance during mixing and compaction, shearing, and recovery of shear strength was demonstrated. The cargo used for sand improvement, a hardening oil, tung oil, was encapsulated in calcium alginate capsules by the ...
The first stage of the program involved testing of fifteen high-strength concrete stub columns under concentric axial compression. The concrete compressive strength was about 69 MPa (10,000 psi). In addition, a large database including eighty-six similar tests conducted by other researchers was ...
Shear behavior of laboratory-sized high-strength concrete beams reinforced with bars and steel fibers Synopsis: This paper reports on an investigation on the behavior of high-strength concrete beams (with concrete compression strength equal to 11,600 psi or... SW Shin,JG Oh,SK Ghosh - 《Aci ...
Nineteen reinforced concrete deep beams with compressive strengths in the range of 41 MPa ≤ fc′ ≤ 59 MPa (6000 psi ≤ fc′ 8600 psi) were tested under two-point top loading. All the beams were singly reinforced with main steel percentage ρ = 1.23 percent and with nominal percentage of...
Compressive strength is defined as the maximum compressive load a body can bear prior to failure, divided by its cross sectional area. Ceramics typically have good tensile strengths and are used under compression e.g. concrete. Shear Strength ...
