Study of castellated beam using stiffeners a revieweSAT Journals
Abstract Now-a-days the use of castellated beam has been admired due to its beneficial functions like light in weight, easy to erect, economical and stronger. The castellated beam is manufactured from its parent solid I beam by cutting it in zigzag pattern and again joining it by welding, so that the depth of the beam increases. Hence, due to increase in depth of beam load carrying capacity of the parent I section is increased with same quantity of material. The increase in depth of castellated beam leads to web post buckling and lateral torsional buckling failure when these beams are subjected to loading. There are many other modes of failure like formation of flexure mechanism, lateral torsional buckling, and formation of vierendeel mechanism, rupture of the welded joint in a web post and shear buckling of a web post which needs to be taken care of. Study shows that use of stiffeners in the web portion of beam helps in minimizing these failures. Therefore, a detailed study in respect of number of stiffeners, size of stiffener and there locations in the web portion of castellated beam needs to be carried out. Hence, in the present paper an attempt has been made to review existing literature, concerned with strength of beam using stiffeners. The literature survey indicates that use of stiffeners in web portion of castellated beams helps in increasing the strength and also minimizing the deflection. Researchers have suggested using stiffener along the edges in order to reduce the stress concentration along openings.. Key Words: openings, castellated beam, cellular beam, stiffener, thickness.
SHEAR PERFORMANCE OF FIBER REINFORCED SELF COMPACTING CONCRETE DEEP BEAMSIAEME Publication
The self-compacting concrete (SCC) is the newest innovating category of high performance concrete. The shear behavior of Fiber Reinforced Self-Compacted Concrete (FRSCC) deep beams was investigated. The experimental program consisted of twelve simply supported beams tested up to failure under four-point load. The key parameters covered in this investigation were steel fibers ratios (0.0, 0.50, 0.75 & 1.00%) and the effective shear span to depth ratio; a/d that varied from 0.6 to 1.0. Also, the main flexure reinforcement ratio was variable (1.0, 1.60 and 2.20 percent). In addition, vertical and horizontal web reinforcement effect was investigated. The mid-span deflection, cracks, reinforcement and concrete strains of the tested beams were recorded and compared. Test results pointed out that the steel fibers enhanced the cracking load, ultimate capacity, displacement and energy absorption of the tested FRSCC deep beams.

Structural Analysis and Design of Castellated Beam in Fixed ActionAM Publications
The depth is the most important parameter which governs the sectional property of the section. For the serviceability moment of inertia plays very important role and moment of inertia of I-section is directly proportional to the third power of the depth. Research on cellular beams with circular web openings is very limited and is less developed than Cellular beams which may be attributed to the fact that cellular beams are more complicated to analyze due to their continuously changing section properties around the cell.
Analysis of Prestressed Concrete Girder for Bridgesijtsrd
Today bridge building has gained worldwide importance. Bridges are the key elements in every road network and the use of pre stressed girder bridges is becoming more and more popular in bridge construction due to their better stability, service friendliness, economy and durability, aesthetic and structural appearance. Typically reinforced concrete construction, steel construction or steel composite construction is used. In the case of high spans, reinforced concrete construction is uneconomical due to the larger span. , the cross section is used more efficiently than the reinforced concrete cross section. Pre stressed concrete is used for long span bridges with a span of more than 10 m. Conventionally, when calculating bridges, the superstructure and substructure are analyzed separately. The superstructure is usually a grid made up of main girders, transverse membranes and a deck slab. a grid of linear elements The columns of the main girders are anchored. The superstructure is examined according to IRC 62014 and according to IRC 182000 for unconsidered gravitational loads and moving vehicle loads. Reduction of the stress level and also of the deflection compared to the straight tendon profile. Avinash Kumar Vidyarthi | Dr. P. K.

Behavior Of Castellated Composite Beam Subjected To Cyclic Loadsirjes
The purpose of this study is to determine the behavior of beam-column sub-assemblages castella
due to cyclic loading. Knowing these behaviors can if be analyzed the effectiveness of the concrete filler to
reduce the damage and improve capacity of beam castella. Test beam consists of beam castella fabricated from
normal beam (CB), castella beams with concrete filler between the flange (CCB) and normal beam (NB) as a
comparison. Results showed castella beam (CB) has the advantage to increase the flexural capacity and energy
absorption respectively 100.5% and 74.3%. Besides advantages, castella beam has the disadvantage that
lowering partial ductility and full ductility respectively 12.6 % and 18.1%, decrease resistance ratio 29.5 %
and accelerate the degradation rate of stiffness ratio 31.4%. By the concrete filler between the beam flange to
improve the ability of castella beam, then the beam castella have the ability to increase the flexural capacity of
184.78 %, 217.1% increase energy absorption, increase ductility partial and full ductility respectively 27.9 %
and 26 %, increases resistance ratio 52.5 % and slow the rate of degradation of the stiffness ratio 55.1 %..

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
