Abstract: Reinforced concrete elements with a high longitudinal and transverse reinforcement ratio may present conflicts on both of them, resulting in reduced labor productivity poor job when assembling the transversal reinforcement, reducing its effectiveness. Thus, this research presents type internal as an alternative to mitigate conflict between bars. A total 5 reinforced wide beams were ma...

Over the past few decades, numerous studies have explored use of steel fiber (SF) as an alternative to transverse reinforcement rebars in reinforced concrete beams, either partially or completely replacing them. However, there are limited that investigated effect dosage and length on beam performance under torsional loads without rebars. In this study, experimental investigations were conducted...

Existing reinforced concrete (RC) members, designed in accordance with obsolete codes, are often characterized by high stirrup spacing. The collapse mechanisms generated spacing typically related to the buckling of longitudinal reinforcement and can be accentuated when corrosion takes place. In this paper, new refined material constitutive laws for steel, including inelastic reinforcement, impl...

This study aims at exploring ways of making the use of bamboo reinforced concrete beams simple, efficient and cost-effective for rural construction with Ghana as a case study. It is a comparative study of bamboo reinforced concrete beams with shear links made of different materials. The web materials considered were bamboo, rattan cane and steel. Sixteen (16) beams were tested to failure under ...

This paper deals with the effect of steel fiber amounts and interaction between amount stirrup ratio on shear behavior capacity reinforced concrete (RC) deep beams fibers. The experimental program was carried out twelve different (0, 30, 40, 65 kg/m3) ratios (0.1, 0.15, 0.25%). test results have shown that use fibers increased resistance (up to 55%), reduced crack width 11 times) deflection 57%...

The article discusses crossbow finds from the territory of historical Mazovia and Dobrzyń Land. These are mainly pieces spanning devices triggers. In latter category we have a lever stronghold (motte) in Lekarcice Nowe as well few bone antler nuts strongholds Czersk, Pułtusk, Warsaw, Wizna. Included among parts there is mechanism castle Liw. Furthermore, stirrups been recovered on Vistula river...

The components of the material structure that are important in calculating requirements iron because have a high value construction work. Iron such as reinforcing columns, beams, pile caps, sloofs, and others widely used for reinforcement. research aims to determine need stirrup reinforcement using method based on field data with Bar Bending Schedule (BBS) approach. BBS minimises waste so it on...
