ANALYSIS AND DESIGN OF MULTI CELL TYPE BOX GIRDER – AN ECONOMICAL ALTERNATIVE FOR LONG SPAN BRIDGES

ABSTRACT

In recent years, single or multi – cell reinforced concrete box girder bridges have been widely used as economic and aesthetic solution for today’s highway systems. The main advantage of this type of bridge lies in the high rigidity in torsion. This is due to the closed box–section and convenience in varying the depth along the span. High torsion stiffness gives them better stability and load distribution characteristics and also makes this form particularly suitable for Grade separations. This hollow section also can be used to accommodate services and has added advantage of less weight.
The paper includes case study of an upcoming bridge at “Surat”, Gujarat. The bridge superstructure is taken as multi cell type box girder. The parametric studies for alternatives of multi cell with three, four, and five cells have been incorporated. Study also includes effect on multi cell with and without inclined web. For analysis IRC-6 vehicle loading has been considered. The software modeling and FEM analysis is to be carried out and the results of moment and shear distribution for each cell would be compared with results form empirical methods. This paper is oriented to give the most effective alternative for upcoming bridge.

AIR POLLUTION CONTROL BY BIOLOGICAL TREATMENT

Abstract

Industrial air emissions are generally contaminated with one or more of
the air pollutants namely dust, fumes, gas, mist and vapor. There has also been increasing concern over the emission of hazardous air pollutants (HAPs), smog pre- cursors and odors from industrial facilities. Contaminants are commonly removed from industrial waste air by thermal treatment, activated carbon adsorption, or scrubbers. Thermal treatment includes direct flaring or catalytic oxidation. This is effective at high concentration of the organic pollutant. However, it becomes too costly when concentrations are low because a secondary fuel has to provide the majority of the energy required to oxidize the contaminant. In activated carbon adsorption, compounds are adsorbed on to the surface of the carbon, producing a very clean effluent. However, the amount adsorbed per unit mass of carbon is related to the concentration of the contaminant in the air. Low concentrations cause a low adsorption rate; therefore, the amount of carbon required per unit mass of contaminant becomes too large as concentrations decrease. Scrubbers are effective for removing many odors and other highly soluble compounds, but suffer from very high operational costs and the production of a secondary waste stream – compounds are transferred but not destroyed.

ACTIVE CONTROLS IN BRIDGE ENGINEERING

ABSTRACT

Bridges are the key elements in any road network. The Conventional design procedures for bridges are generally based on two requirements namely safety and serviceability. For the Safety concerns the bridges are designed by Strength approach, which ascertains that the strength of various elements is greater than the demand at extreme loading condition.

In the presence of seismic loads, the bridges designed with strength approach can sometimes be untenable both economically and technologically. To overcome this problem isolators are provided to isolate the seismic ground motions or passive energy dissipation devices are used to dissipate the vibration energy and reduce the dynamic response. Recent trends are to use newly developed active control devices which have unique advantages and provide more control authority and adaptivity when compared to alternative ways. Based on the changes of structural responses and external excitations, these intelligent systems can actively adapt their properties and controlling forces to maximize the effectiveness of isolation system, increase the life span of bridge and allow it to withstand the extreme loading effects. A purely active control system may not have proven reliability. In nutshell, an active control system incorporating devices like active tendon, bracing and mass dampers has an advantage of being a SMART system but suffers in terms of external energy utilization, destabilization and complication of system performance.

WATERSHED DEVELOPMENT

ABSTRACT

Water is the life line of all the development activities and for survival of plant and animal lives. Nevertheless, about 25% of the villages in India are deprived of potable water. About 75% water sources in rural areas do not meet the WHO standard and only about 28% of the
agricultural lands have assured source of irrigation. This situation is not because of scanty rainfall but due to inefficient use of precious precipitation.

In recent years India has looked to watershed development as a way to realize its hopes for agricultural development in rain fed, semi-arid areas. By capturing scarce water resources and improving the management of soil and vegetation, watershed development has the potential to create conditions conducive to higher agricultural productivity while conserving natural resources. This case study of the water shed development project at Chitrakoot (Madhya Pradesh), fits squarely into works on development strategies on less favoured lands – areas where agro climatic conditions are difficult or infrastructure and support services have been neglected. The analysis compares conditions in the study villages before and after the project was implemented. Quantitative analysis at the village level examines performance indicators such as changes in access to irrigation water, employment opportunities, soil erosion and conservation on uncultivated lands, drainage lines, social and economic upliftment of the inhabitants.

GREEN HOUSE EFFECT

ABSTRACT

Have you ever thought of what keeps our planet warm enough to sustain life on it. Ya, the instant idea came to your mind must be “SUN” but the inside story tell us something different.

The gaseous blanket surrounding the earth from dangerous ultraviolet radiations coming from the sun. The atmosphere plays an vital role in maintaining the heat balance on the earth by absorbing the infrared radiating received from the sun and re-emitted by the earth. This is what we call “GREEN HOUSE EFFECT”.

The earth is heated by the sunlight and some of the heat that is absorbed by the earth is radiating back into space. Some of the gases in the lower atmosphere acting like glass in a green house, allow the radiation but do not allow the earth to re-radiate the heat into space. In other words we can say that these gases in the atmosphere are transparent to sunlight that strongly absorbs infra-red radiation which earth reflect back as heat A part of the heat so trapped in theses atmospheric gases is reemitted to the earth’s surface resulting in heating of earth’s atmosphere.

In fact the ‘Green House effect’ are responsible for keeping our earth warm to sustain life on it. If the concentration of these gases are very less the temp will drop to 00 C, if there concentration became very high the heat trapped by them will be more, which may threaten the existence of life on the earth.

Geo Textile and Geo synthetic

ABSTRACT

In the present scenario the importance of smart construction materials with various applications is growing rapidly. Soil reinforcement is not a new concept but the principles are already existing in nature and demonstrated by animals, birds & plants. The scientific basis for the modern concept of soil reinforcement lies in idealization of the problem of soil reinforcement in the form of each soil reinforced by high strength thin horizontal members.
This paper focuses the use of Geosynthetic materials like steel, concrete, glass fiber, rubber, aluminum, thermo-plastics, as reinforcing materials. Also the paper focuses the generic classification of the geosynthetics, their functions and their applications in Railways, Airports, hydraulic structure, marine engg. Structures, landslides, etc.

SYNTHESIS OF ZEOLITES FROM FLY ASH

ABSTRACT

Proper utilization of fly ash has become a pressing issue today. Large quantity of fly ash is produced by the coal fired thermal power plants throughout the world, In India, more than 90 million tons of fly ash is being generated annually with 65 000 acres of land being occupied by ash ponds. The World Bank has cautioned India that by 2015, disposal of coal ash would require 1000 square kilometers or one square meter of land per person. Currently coal based thermal power plants contribute 70% of power production in the country generating a massive amount of fly ash. This is causing tremendous impact on environment in India
In view of high cost of disposal and environmental pollution, the gainful utilization of fly ash to maximum extent is of vital importance. Therefore, development of a technique for the treatment of coal fly ash is indispensable to the recycling and utilization of waste matters.
In the present project an attempt has been made to synthesize zeolite from waste coal fly ash, and utilize this treated fly ash as catalyst for industrially important processes like catalytic cracking of n-heptanes.

ENERGY RECOVERY AND ELECTRIC POWER GENERATION FROM MUNICIPAL SOLID WASTE

ABSTRACT

The enormous increase in the quantum and diversity of waste materials generated by anthropogenic human activity and their potentially harmful effects on the general environment and public health, have led to an increasing awareness, world-wide. Therefore, and urgent need to adopt scientific methods for safe disposal of waste and recovered valuable energy from it. There is and obvious need to minimize the generation of wastes and to reuse and recycle them, the technologies for recovery of energy from wastes can play a vital role in mitigating the problems.
Besides recovery of substantial energy, these technologies can led to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner while meeting the pollution control standards.
This paper gives some basic information about Municipal Solid Waste (MSW) and its utilization for Energy Recovery, besides a method for enough estimation of power generation potential from MSW through the main conversion process. It is also shown that, in general, 100 tones of MSW can generate about 1.0-1.5 MW power.
