Abstract:
 

This report documents the Stage 2 design of a sustainable and affordable bamboo pedestrian bridge in Naladapada, at Katri Gram Panchayat region of Nandurbar District, Maharashtra, where 14 tribal hamlets get completely isolated during the heavy monsoons every year due to floods. After a Stage 1 feasibility study, this work uses a combination of GIS-based site selection, hydrological studies, and structural modeling by STAAD. Pro, actual field construction, and testing of the treated bamboo in laboratories to transform the design from just a concept to a hybrid standing structure on the riverbed. The major factors of river-flow convergence, valley shape, and flood records of the site led to the selection of the Naladapada location as the most strategic as well as the most flood-prone place in the cluster.

The structural behavior of the bamboo arch superstructure for dead, pedestrian live, wind, earthquake, and moving loads was studied by the three-dimensional finite-element method. The study revealed that the load due to the live presence of pedestrians has the most influence on the design, with the deflections still being well within the allowable limits and lateral-torsional buckling not being a factor for the design.

The hybrid system construction was based on a reinforced-concrete substructure with the bamboo-arch superstructure, connected by steel threaded rods, mortar-filled bamboo interfaces, and precast connectors. The bridge site work from November 2025 to May 2026 showed that with bamboo that is locally available, labor of the community, and very few machines, the bridge assembly is possible. However, compression tests on the treated Dendrocalamus strictus carried out in the laboratory confirmed the material properties used in the design and the structural layout.
