Comparison of Deployable Bridges Having Similar Geometry but Different Material- Steel and Bamboo

Abstract

This study aims to evaluate the structural, environmental, and economic implications of incorporating bamboo into the design of deployable pedestrian bridges. Deployability adds another layer of complexity, requiring the bridge to be easily transportable, assembled, and disassembled as needed, making it suitable for temporary installations or emergency situations. In this paper to check the comparative analysis of deployable pedestrian bridge by using steel and bamboo materials 2 different cases made, the objectives has decided and the result have drawn. The recommendations have discussed after the conclusion that using steel material, the performance of the steel material is more as compared to bamboo material. As per weight and economic point of view, bamboo concluded as the lighter in weight, cost effective and eco-friendly material.

Introduction

I. INTRODUCTION

Pedestrian bridges serve as vital links in urban infrastructure, facilitating safe passage over obstacles and enhancing connectivity within communities. In recent years, there has been growing interest in sustainable construction practices, prompting exploration into alternative materials such as bamboo alongside traditional choices like steel. This analysis delves into the feasibility and performance of a deployable pedestrian bridge constructed with a combination of steel and bamboo materials. The utilization of steel in bridge construction is well-established, offering strength, durability, and versatility. However, concerns over environmental impact and sustainability have prompted researchers and engineers to seek alternatives that reduce carbon footprints without compromising structural integrity. Bamboo has emerged as a promising candidate due to its rapid growth, high strength-to-weight ratio, and renewability.

II. DEPLOYABLE PEDESTRIAN BRIDGE

Deployable pedestrian bridges stand at the forefront of contemporary civil engineering, offering innovative solutions to urban connectivity challenges. These bridges, designed for rapid assembly, disassembly, and transport, provide vital pedestrian access over temporary obstacles such as construction sites, rivers, or event venues. The emergence of deployable bridges reflects a dynamic approach to infrastructure development, catering to the fluctuating demands of modern cities. Unlike conventional permanent structures, deployable pedestrian bridges offer flexible, temporary solutions suitable for emergency situations, special events, or temporary construction needs.

Factors that are used for key areas to focus on:-

1. Structural Considerations
2. Deployment Strategies
3. Transportation Logistics
4. Safety and Accessibility
5. Case Studies and Applications

III.  PROCEDURE AND 3D MODELLING OF THE STRUCTURE

Conclusion

Conclusions for comparison of deployable bridge made up of steel and bamboo material are as follows:- 1) On comparing maximum displacement values, bamboo deployable bridge generates more displacement as compared to steel bridge with a value of 8.342 mm, 14.682 mm and 3.663 mm for x, y and z direction respectively. 2) Observing the axial force values, it is decreasing by 0.33% as compared to steel material used. 3) Comparing the shear forces in members, shear increases along y by 0.38% but shear decreases along z by 34.74% when using bamboo material. 4) Comparing the bending moment in members, moment decreases along y by 25.8% but moment increases along z by only 0.43% when using bamboo material. 5) Torsional moment seems to be more when using the bamboo material with a value of 10.162 KNm. 6) When comparing the stresses values, the axial stresses decreases by 0.34% when using the bamboo material, the shear stresses in members increases along y by 0.04% but stresses decreases along z by 34.74% when using bamboo material. Finally the bending stresses in members, stresses decreases along y by 25.8% but moment increases along z by only 0.44% when using bamboo material. This part of the project concluded that when using steel material, the performance of the steel material is more as compared to bamboo material. On contrasting to the weight and economic point of view, bamboo concluded as the lighter in weight, cost effective and eco-friendly material.
