Results also show that low amounts of shear reinforcement tend to eliminate the trend of decreasing shear strength with increasing height. When low levels of shear reinforcement are taken into account in the strength calculation (that is, V_n=V_c + V_(s,min)), ...
On the basis of the exposition on the calculation formula of shear capacity in the code for design of concrete structures(GB50010—2002),the placed condition of the minimum of stirrup reinforcement ratio is discussed.And the placed condition of the minimum of stirrup reinforcement ratio is put fo...
Minimum shear reinforcement for thick plates and two-way slabs Thick reinforced concrete plates of over 250 mm thickness usually exhibit brittle shear failure under concentrated loads. Potential punching failures in th... E Rizk,H Marzouk 被引量: 0发表: 2013年 Experimental validation of the minimu...
The minimum of the entered shear reinforcement can be controlled by two settings: Window 1.4 - Reinforcement Ratios - Minimum Shear Reinforcement Ratio Window 1.4 - depending on the standard, for example, for DIN EN 1992-1‑1 - Minimum Shear Reinforcement Please note that the minimum shear rei...
Steel plate Concrete (SC) has been used for the shield building in nuclear power plant AP1000 recently. However, the minimum shear reinforcement ratio for SC beams is unknown. This paper reports thatdoi:10.1617/s11527-015-0763-7Feng Qin...
The results of an experimental appraisal of the ACI Building Code provisions allowing the use of deformed steel fibres as minimum shear reinforcement in reinforced concrete beams are presented. Two types of hooked-end steel fibres of lengths 35 mm and 60 mm were used in the fibrous concretes ...
Minimum shear reinforcementReserve strengthShear capacitySafety marginThe Australian Concrete Code (AS 3600) went through a number of significant changes to the shear provisions in the last decade through the introduction of the modified compression field theory. However, there were some discrepancies ...
An appraisal of crimped and hooked-end steel fibres as minimum shear reinforcement in reinforced concrete beams made with two concrete grades is presented. Beams conventionally detailed with minimum shear reinforcement were used as control specimens. The fibre reinforced beams also showed varying degrees...
There are substantial differences in the maximum stress limits and minimum shear reinforcement requirements that are used in codes of practice. A database of 1287 shear test results was used to evaluate the requirements/limits that are used in the ACI318-02 Building Code, the AASHTO-LRFD Bridge...
This research aimed to study the minimum requirements of shear reinforcement for ultra high performance fiber reinforced concrete deep beams. The experimental results showed that increasing the provided vertical web reinforcement ratio has slight effect on the diagonal cracking strength and the ultimate ...
