Design and Construction of First Network Arch Bridge in Nepal
摘要
Arch bridges are timeless architectural wonders known for their aesthetic appeal and structural excellence. They have a rich history, stretching back to ancient civilizations, and continue to stand as symbols of engineering ingenuity and artistic achievement. The Network Arch is an arch structure where the hangers supporting the lower tie (deck) are inclined in opposite directions and they cross one another at least twice. The inclined hangers with multiple intersections make the network arch bridge act like a truss, with only axial, compressive and tensile forces. Bending moments and shear forces are very small in network arches. This paper explains the design and construction aspect of first network arch bridge in Nepal. The successful construction of this bridge in Nepal has not only ushered in a new era of connectivity and infrastructure but has also ignited a wave of confidence among Nepalese engineers. This significant achievement marks a turning point in the country’s engineering prowess, as it emboldens the nation to take on more ambitious projects that were once thought unattainable.
