Introduction
The idea of paper bridge first emerged after discovering the information of one such cable stayed bridge which was constructed by the students of IIT Madras during their annual tech-fest ‘Shaastra’ in 2002. Students of MEFGI wanted to do something creative and unique which was never built before. So, it was finally decided to construct bridge made out of newspaper and other unconventional biodegradable materials. Hence system of suspension bridge was adopted because of its pleasing elevation along with good structural strength and with an intention to for studying force distribution patterns.
The main principle involved in making of the bridge was only to learn the force distribution patterns, load carrying capacities, endurance against compression and tension as well as working in a team and in an organized way by following time management strategies. It was indeed a great learning experience for all the students involved in the making of the paper bridge. Design, material testing, fabrication and assembling of all the elements of the bridge got simultaneously completed with ongoing construction of the bridge.
Objectives of Study
The main principle involved in making of the bridge was to learn the force distribution patterns, load carrying capacities, endurance against compression and tension as well as working in a team and in an organized way. The main aim of the bridge was to make it possible for people to walk on it safely. Additionally, the comparative analysis of behavior of paper members with concrete structures were aimed at. Different strength properties of paper can be investigated.
Scope of Study
Many books were referred to study the properties of paper and many unsuccessful trials were made in order to prepare the biodegradable gum. The theories of basic fundamentals of load transfer and force distribution patterns were studied and were subsequently applied.
Several limitations were also encountered at the beginning stage. Paper is fragile material which is also irrepressible against water and fire. These limitations were very difficult to overcome. Also, the paper gets abrasive after passage of time. The newspaper is manufactured in such a way that it can resist more shearing force when teared in longitudinal direction than in transverse direction.
