Introducing a row of holes at the neutral axis of a beam under pure bending effectively reduces the self weight of the beam. The amount of weight reduction... NK Naik,VK Ganesh - 《Composite Structures》 被引量: 2发表: 1993年 Replacing traditional stirrups by shear steel pate with high ...
The beams were tested in flexure in a specially designed fourpoint bend test fixture. The load versus displacement and surface strains at the apex of the beam were recorded to examine the response. It was observed that the debonded face sheet lifted off of the core and underwent a ...

This method is relatively simple and considerably enhances the bond of the mounted Glass fiber reinforced polymer reinforcements, thereby using the material more effectively. This paper provides a critical review of existing research in this area, identifies gaps of knowledge, and outlines directions ...
The largest beam was 250 mm wide, 600 mm deep and had a clear span of 3.1 metres. Test parameters included the concrete cover to the shear reinforcement cage, shear reinforcement ratio, longitudinal tensile steel ratio, overall beam depth, shear span-to-depth ratio and concrete compressive ...
Experimental and theoretical studies on shear strength of large reinforced concrete beams are presented. The shear strength of a reinforced concrete beam without shear reinforcement gradually decreases as an effective depth d of a beam i... Hong,Ki-Nam,Han,... - 《Journal of the Korean Society...
The results show that both the shear strength and the serviceability performance of deep beams are significantly improved by the use of prestressing and by the use of orthogonal web reinforcement. The following factors were also investigated: deep beam deformation, ultimate behaviour, various cracking ...
The research covered in this thesis is concerned with the effects of the behaviour and load carrying capacities of classes of steel beam structures with various shapes of web openings. A comprehensive investigation on non-composite and p... KD Tsavdaridis 被引量: 14发表: 2010年 ...
However, the effect of the compressive axial force on the plastic moment resistance is not considered. Moreover, for cases where the beam columns fail by elastic or elastic-plastic bulking mode, BS5950 method may provide overestimated prediction of member strength [5]. A considerable amount of ...
This paper reports the results of a testing program on ultrahigh-performance steel fiber-reinforced concrete beams. Eight prestressed concrete beams were tested in shear with the test variables being the shear span-to-depth ratio and the quantity and type of steel fibers. The results of the ...
