Introduction Model truss bridges are a staple in engineering education and hobbyist circles, serving as both practical demonstrations of structural principles and creative projects. The selection of materials for constructing a model truss bridge is a critical decision that influences the bridge

A truss bridge is a type of bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, typically forming triangular units[10]. These elements may be stressed from tension, compression, or sometimes both in response to dynamic loads[10]. Truss bridges are one
