Experimental Study on Alignment of Lapped Bars in Tension Region in Fiber Reinforced Concrete Beams
- SoumyaChandran P, Linjesh Sebastian
Abstract
Lap splices are widely used in masonry structures because of limited lengths of rebars combined with relative ease of construction and cost when compared to other splicing methods. Major design codes encourage staggering lapped joints in tension by imposing a penalty on lap length depending on the proportion of bars lapped at the same section .Staggering lapped joints increases the complexity of detailing and steel fixing, and may require additional resources and slow construction on site. An experimental program has been conducted in order to investigate the flexural behaviour of concrete beams by changing the alignment of tension reinforcement lap splice. A test series of four simple beams containing different lap splice length is been going to conduct in this investigation. The beams are of 2000 mm total length and 180*230 mm cross section. The parameters included in the experimental program are the splice length and the bar diameter 12mm. A traditional volume fraction of hooked steel fibers was adopted for FRC. The beam which is lapped in staggered manner without leaving a gap is found to fail at 110.6kN with a deflection of 11.95mm.Which has got good load carrying capacity as compared to other beams. As compared to control specimen the beam which is lapped in staggered manner without leaving a gap (B3) is found to have an increase of 13.38% of ultimate load and 62% of increase of deflection and first crack is formed at load of 40kN has got an increase of increase of 33.5%.

Strengthening of RC Beam with Web Bonded Steel Plates
- Swetha K S, Rona Maria James
Abstract
Structures may be required to improve the structural behaviour and repair of damaged structures to restore structural performance for economical reasons. Steel plates are one of the most common materials for strengthening of reinforced concrete beams; it is very effective for increasing the flexural and shear capacity of reinforced concrete beam. From various studies it was understood that web bonded steel plates affects the crack patterns of the beams significantly and the position of web bonded steel plates significantly influences the stiffness and flexural capacity of plated beams. The critical gap in research is to study the flexural capacity of RC beam with web bonded steel plates by varying the plate thickness and to find the effective thickness of steel plate based on flexural capacity and crack pattern and to study the flexural capacity and crack pattern of RC beam strengthened with web bonded steel plates having effective plate thickness by varying plate depth. This paper deals with an experimental program conducted on the flexural capacity of RC beam without strengthening and 5 RC beams strengthened with web- bonded continuous steel plates. The control specimen and the beam with web bonded steel plates of 4 mm thick, 3 mm thick and 1.6 mm thick were tested by using loading frame. The results are compared based on the parameters ultimate load, deflection, and load at first crack and the effective thickness of steel plates is found out and beams strengthened with web bonded steel plates of various widths are studied based on the same parameters. The test results confirmed the effectiveness of web bonded continuous steel plates for strengthening of RC beams. From the comparative study it is obtained that, the beam with web bonded steel plates having 4mm thickness and 80mm width shows higher strength, lower deflection and higher load at first crack as compared to other specimens.

Experimental Investigation on Two Way RC Slabs with Textile Reinforced Mortar
- Anjali P V, Biju Mathew
Abstract
Textile-reinforced mortar (TRM) is a cement-based composite material that consists of high-strength fibers in the form of textiles combined with inorganic matrices, such as cement-based mortars. The application of textile-reinforced mortar (TRM) as a means of increasing the flexural capacity of two-way reinforced concrete (RC) slabs is experimentally investigated in this study. In this paper, the effectiveness of textile-reinforced mortars (TRMs), the strengthening configuration on the basis of different orientation and the role of initial cracking in the slab is to be investigated experimentally. Here, a new type of textile (nylon-based textile) is used as strengthening material. Also Polymer-modified cementitious mortars were used as binding material for the textile sheets. For this purpose three large scale RC slabs were casted and tested under point loading in loading frame equipment. It is concluded that TRM increases the cracking load and hence the flexural capacity of two-way RC slabs, also the strengthening configuration plays an important role in the effectiveness of the technique.

Comparative Study On Bond Strengths Of Reinforcing Bars Embedded In Conventional And Geopolymer Concretes
- Kambham Amani, Dr Y.Ramalinga Reddy
Abstract
Conventional concrete and Geopolymer concrete has been investigated thoroughly in recent times with respect to mechanical strength properties throughout the world. However, that is related to structural behavior of these concretes which needs to be taken up urgently in order to make them acceptable in field applications by practicing engineers. In this regard, studies to bond strength of reinforcing bars with concrete are of greater significance. The attainment of satisfactory performance in bond, when efficiently developed enables the concrete and steel to form composite structure which is the most important aim of reinforcement in RCC structural members. Bond stress in RC members arises due to anchorage of bars in Tension or Compression; anchorage bond problem is merely of determining of the length of embedment required to resist the withdrawal of reinforcing bars. Earlier investigations in conventional concretes and GPCs for straight bars proved that GPCs has better performance than conventional concretes in case of bond. Hence, in the present study it deals about the experimental and numerical work relating to the finite element modeling using ANSYS version 15.0 to correlate the bond strength of straight bars and L-bends/ 90̊ bends in geopolymer concrete with that in conventional concrete cubes using Pull out test as per Indian codal provision IS 2770:1967.Standard test specimens with respect to compressive strengths were casted and tensile strength of the rod has been found out for using the data to model in ANSYS version 15.0 and the model developed is validated with experimental data of straight bars and L-bends on geopolymer concrete and conventional concrete.

Verification Of Reynolds Number By Density Method
- Mr.Sreenivasulu Reddy, Dr.Y Ramalinga Reddy
Abstract
The laminar and turbulent flow the density of fluid plays vital role in classification of flows. In present study an attempt made to verity the Reynolds number by varying the density of flowing fluid. A in this study fine filament of dye is introduced in to the flow of water through the glass tube where different types of flow are seen at its entrance. At low velocities the dye filament appeared as straight line through the length of the tube and parallel to its axis, characterizing laminar flow. As the velocity is increased the dye filament becomes wavy throughout indicating transition flow. On further increasing the velocity the filament breaks up and diffuses completely in the water in the glass tube indicating the turbulent flow. Keyword: Reynolds number, Laminar Flow, Turbulent flow, density, relative density ×

- Dr.Y Ramalinga Reddy, Mr.Sreenivasulu Reddy
Abstract
Rainfall and runoff are main substantial constitute sources of water for storage and recharge of ground water in the water shed. Evaluation of availability of water is most essential by understanding the rainfall and runoff pattern. The surface water resources are available in the watershed from national highways and state highways. The present study is done form an area about 160km2 in national highway is the main catchment area of the basin and same considered for runoff model. Runoff keeps rivers and lakes full with water but also changes the landscape by the action of erosion. Only about 35% of the precipitation ends up in oceans and seas, other 65% is absorbed into soil and remaining is evaporate. Lake Sediment removal is usually undertaken to deepen a lake and increase its value to enhance irrigation practices and fishery etc. Keyword: Rainfall, Runoff model, Ground water, Lakes ×
