This document is a seminar report submitted by 6 students to MIT Academy of Engineering about the fabrication and testing of a bamboo Baltimore truss bridge. It includes an introduction, planning of the truss bridge, pre-test analysis of bamboo members, compression and tension testing of bamboo specimens and joints, fabrication of the bamboo Baltimore truss bridge, testing of the completed bridge, results, and conclusions. Testing of the completed bridge showed it could withstand a maximum compressive load of 5.3 kN before failure.

- 3. Civil Prototyping MIT Academy of Engineering iii | P a g e ACKNOWLEDGEMENT I would like to express my sincere thanks and gratitude to professor Dr. Amrut Joshi Sir for his continuous and unfailing support, guidance and help, which have been invaluable during the course of this project. His knowledge, insight and constant motivation at each step of the project has been instrumental in its completion. I would like to take this opportunity to thank the entire staff at Structures Laboratory and the Civil Engineering Laboratory for their cooperation and assistance in the lab-work that was required for this project.

For the structure, the design of base plate, inclined and top members, and joints of the structure have been carried out. For the design of joints, the experimental testing of bamboo joints has been carried out in the compression Testing Machine in the civil engineering Laboratory. The manual analysis of the forces and moments has been carried out. fabrication of the truss has been done by the completion of pretest analysis of bamboo joints. The design details have been depicted with figures and labelled. Using compression testing machine, a test has been carried out at a bridge truss. it holds a maximum compressive strength of 5.3 KN, and then it breaks down.
