Sir,
I am searching for a paper presentation topic on construction challenges for bridges in hilly areas. It's urgent since I need it for my upcoming seminar.
I would therefore request you to kindly send me a ppt of this topic as soon as possible.

Thanking You. ....etc

Abstract:
In this seminar the analysis of soil-structure interaction effects and of multiple support excitation on the seismic response of long-span cable-supported bridges are presented. The purpose of this seminar is to provide a better understanding of the dynamic performance of cable supported bridges under earthquake excitation, considering the spatial variability of the ground motion and the complex phenomena of soil-bridge interaction, so that such effects can be included in the design and rehabilitation process. Amplification of struct ....etc

Abstract:
This seminar is intended to evaluate the applicability of Nonlinear Static Procedure by implementing the Displacement Coefficient Method to bridges. For comparison purposes, the Nonlinear Dynamic Procedure (or nonlinear time-history analysis), which is considered to be the most accurate and reliable method of nonlinear seismic analysis, is also performed. A three-span bridge of 97.5 meters (320 ft) in total length was analyzed using both the Nonlinear Static Procedure/Displacement Coefficient Method and nonlinear time-history. Nine ....etc

Bridges are lifeline structures. They act, as an important page link in surface transportation network and failure of bridges during a seismic event will seriously hamper the relief and rehabilitation work. There are many cases of damage of bridges in the past earthquakes all over the world. Due to their structural simplicity, bridges are particularly vulnerable to damage and even collapse when subjected to earthquakes. The fundamental period of vibration of a majority of bridges is in the range of 0.2 to 1.2 second. In this range, the structur ....etc

Philosophers, thinkers, intellectuals all appeal, please build bridges and not walls between different communities, nationalities, countries, languages etc, to achieve universal brotherhood. This can be achieved by constructing stress ribbon bridges.
Stress ribbon bridges are very economical, aesthetical and almost maintenance free structure. They require minimal quantity of materials. They are erected independently from the existing terrain and therefore they have minimum impact upon the environment during construction.

PROTECTIVE COATINGS FOR CONCRETE BRIDGES



Protection of structures is very important for increasing the life of the structure. There is a growing national concern about premature deterioration of our concrete infrastructure projects such as bridges, aqueducts etc. requiring early repair and/or replacement. Use of protective coatings will increase the durability and hence the life of these structures. As most of these structures are made up of concrete and steel, the role that coatings play in protecting the s ....etc

INTEGRAL BRIDGES


INTRODUCTION
Integral bridges in simple words, can be defined as bridges without joints. Integral bridges are characterized by monolithic connection between the deck and the substructure (piers and abutments). They span from one abutment, over intermediate support to the other abutment, without any joint in the deck. Integral bridges have been constructed all over the world including India.

Bridges constructed without any expansion joint (between spans or ....etc
