|1||Retrofitting of Existing RCC Buildings by Method of Jacketing Abstract – Many parts of the country have suffered earthquake in last three decades. In costal part of South India faced Tsunami. In first three earthquakes it was found that many of damaged structures were build in non-engineered masonry techniques. Unreinforced masonry structures are the most vulnerable during an earthquake. Normally they are designed for vertical loads and since masonry has adequate compressive strength, the structures behave well as long as the loads are vertical. When such a masonry structure is subjected to lateral inertial loads during an earthquake, the walls develop shear and flexural stresses. The strength of masonry under these conditions often depends on the bond between brick and mortar (or stone and mortar), which is quite poor. This bond is also often very poor when lime mortars or mud mortars are used. A masonry wall can also undergo failure in-plane shear, if the inertial forces are in the plane of the wall. Shear failure in the form of diagonal cracks is observed due to this. However, catastrophic collapses take place when the wall experiences out-of-plane flexure. This can bring down a roof and cause more damage. Masonry buildings with light roofs such as tiled roofs are more vulnerable to out-of-plane vibrations since the top edge can undergo large deformations. It is always useful to investigate the behavior of masonry buildings after an earthquake, so as to identify any inadequacies in earthquake resistant design. Studying types of masonry construction, their performance and failure patterns helps in improving the design and detailing aspects. In previous earthquakes many R.C.C buildings have also collapsed and are found unsafe due to faulty workmanship. Many other causes are responsible for major collapse and damage to the R.C.C structures. The review of the codes shows that there were five zones of earth quakes of Indian subcontinents, But its revision is now shoeing four zones of earth quake. Some part of Gujarat lies in zone V which has largest severity of Earthquake. So as the districts that are located on the boundary of Gujarat – Maharashtra like Nasik, Dhule, Nandoorbar lye in zone III of earthquake zone, zone III is second largest zone of earth quake in India. Therefore it seems to be an compulsion to have an review of the old RCC structures (Likely have completed their service period) in and around Nashik for the structural behaviour to avoid future inconvenience.
This project is just a similar attempt. A health building in the heart of Nashik city is being strengthened to overcome the future disorders. From the physical and experimental investigations it was concluded that the building either should be demolished or at least should be retrofitted with suitable technique to increase its service life.
It was then decided to implement RCC column jacketing technique due to its feasibility and ease for execution.
All the columns on both the floors are now suitably jacketed, the loose pockets of concrete that were investigated during the test are reconcreted, the faulty slabs are completely opened and the rusted reinforcement is replaced with new reinforcement as per the design requirement. And the slabs are recasted with M25 grade of ready mix concrete.

In this paper, we obtain a decomposition of intuitionistic fuzzy continuity in intuitionistic fuzzy topological spaces by using intuitionistic fuzzy w-continuity and intuitionistic fuzzy rw-continuity.||M.

AGVs are employed in nearly every industry, including pulp, paper, metals, newspaper, and general manufacturing. Transporting materials such as food, goods etc are also done. Fork truck vehicles operate just like Truck, truck without driver. In this thesis work, the stresses which appear in the lifting installation of a fork-lift truck at loading-unloading operations are investigated for given input data like load carrying capacity of truck, maximum pressure inside the cylinder, pallet dimensions. Firstly calculate the effects of various loads on the parts of the fork truck in terms of stresses and then compare calculated Stresses with material allowable stresses (yield stress/F.O.S).
After Comparison of Allowable Stresses with generated stresses, we perform FE Analysis and Compare theoretical stresses with FE generated Stresses. Once FE Analysis Results, theoretical Results and Allowable material stresses are compared. We conclude that whether there is a chance of Optimization or not?
If there is a chance of Optimization then reduce fork truck weight by changing various parameters and validate that design with the help of FE Tools.

So, optimizing surface roughness and metal removal rate using various CNC machining parameters including spindle speed (N), feed rate (f) and depth of cut (d) and insert nose radius (r). By developing a mathematical model in CNC milling on a hard steel specimen. And this mathematical model is developed with the help of the design of Matrix. Also CNC (Computer Numerical Control), in which the instructions are stored as a program in a micro-computer attached to the machine. The computer will also handle much of the control logic of the machine, making it more adaptable than earlier hard-wired controllers. This experimental study aims at response surface methodology has been applied for finding the effect on surface roughness and metal removal rate by various process parameters. And after that we can easily find out that which parameter will be more affect.||Hardik B. Patel & Satyam P. Patel|
