This paper presents the findings of an experimental data on the effects of inclined shearreinforcement in reinforced concrete (RC) beam. Two types of shear reinforcement of RC beamwere investigated, conventional stirrups (vertical links) and inclined shear reinforcement (45degrees of inclined shear reinforcement). The RC beam with conventional stirrups wasdesignated as a control specimen. The RC beams with different types of shear reinforcementwere tested for shear under four-point loading system. Comparisons were made between bothtypes of RC beam on load-deflection, load-steel strain, load-concrete strain behaviour and modeof failure. The theoretical and experimental were calculated by using conventional formulation inaccordance to EC 2 in order to verify the experimental results. From the results, it was observedthat the RC beam with 45 degree inclined shear reinforcement improved structural performancein shear by approximately 20% and thus prolong the shear failure behaviour as compared to theRC beam with vertical links.

The Finite Element Analysis

Abstract: Understanding the response of concrete structural components such as beams, columns, walls during loading is indispensable for the development of safeand efficient structures. The present report deals with the non-linear static analysis of a Reinforced Concrete (RC) beam, having dimensions 4000mmX400mmX 250mm, with 4 nos. of 16mm diameter bar as main reinforcements, 8mm diameter at 200mm c/c as shear reinforcement, with two faces of the beam as fixed modeled and analyzed when subjected to two point loads at one-third span from each fixed support using the Finite Element Analysis software Ansys. The behavior of the analyzed beam has been observed in terms of flexural behavior, load-deflection responses, and crack pattern for various loading conditions until failure load. Keywords: Finite element analysis, ANSYS, flexural behavior, Reinforced Concrete (RC) beams, material non- linearity, shear reinforcement.

This paper presents a study of shear behavior of reinforced concrete beam. Generally, shear reinforcement of concrete beam consists of rectangular shape stirrups. when replacing the traditional stirrups by continuous spirally and triangular shape stirrup’s the increase shear carrying capacity of spirally shape stirrups. The spirally shape stirrups reduce the labor cost as well as crack pattern. In this research paper the theoretically shear carrying capacity of rectangular shape stirrups as per design IS456:2000 and experimental shear carrying capacity of rectangular shape stirrups is obtained and that value compared to the spirally and triangular shape stirrups. The present experiment carries 27 beam having cross section 700mm x 150mm x 150mm each set consist 9 beam of rectangular, spirally and triangular shape shear reinforcement with spacing 70mm, 90mm, 110mm. all the beam was tested using four-point loading after 28 days curing. The test result include shear carrying capacity, load-deflection curve, crack pattern. Take a test after 28 days the spirally shear reinforcement improved shear carrying capacity as well as ductility of beam compared to the rectangular and triangular shape stirrups. Hence spiral shear reinforcement shows better result as well as crack performance also deflection at mid span.

Cyclic Loading Tests

Cyclic loading tests simulating the effects of a severe earthquake were conducted on an interior reinforced concrete beam-column joint. The unit had been designed according to
the requirements of the draft (1980) SANZ concrete design code except that the horizontal shear reinforcement in the joint core was deliberately made only 78% of that required by the draft SANZ code. The joint core hoops commenced to yield in the first loading run up to the beam flexural strength and with subsequent loading runs degradation of stiffness and strength occurred due to damage concentrating in the joint core. It
was evident that the draft SANZ code is not conservative in its approach to the design of shear reinforcement for interior reinforced concrete beam-column joints.

Curve Patterns

The purpose of this study was to understand the deflection behavior of reinforced concrete beams using GFRP bar as flexural reinforcement and GFRP sheet as shear reinforcement. The tested beams with dimensions of span length were 3000 mm, width of 150 mm and height of 250 mm of concrete quality f'c.25 MPa. The beams use GFRP bar 3D13 as flexural reinforcement and U-wrap GFRP sheet 50 mm wide with a distance of 100 mm. U-wrap GFRP sheet shear reinforcement is only installed in shear spans. The beam is loaded with two concentrated loads monotonically until it collapses. The test results show that the loaddeflection relationship of GFRP bar reinforced concrete beams with external shear reinforcement of U-wrap GFRP sheet shows two linear curve patterns. The results of the analysis show that the ACI-440.1R-06 approximation equation can be used to accurately predict the deflection in the middle of the GFRP bar reinforced concrete beam with external shear reinforcement from U-wrap GFRP sheet.
