What is the typical span range for adjacent box beams?

The typical span range for adjacent box beams is recognized to be between 20 to 130 feet. This range reflects common engineering practices where box beams, known for their structural efficiency and capability to handle varying loads, are commonly utilized for bridge spans within these dimensions.

Box beams are designed with a closed cross-section that provides both strength and stability, making them suitable for a variety of applications, including vehicular bridges where load distribution and structural integrity are critical. The span range of 20 to 130 feet allows for flexibility in bridge design, accommodating different environmental factors, anticipated loads, and design requirements.

In contrast, other span ranges provided in the options do not represent the typical application of adjacent box beams, which is why they do not align with established engineering guidelines. For effective bridge construction using box beams, understanding this typical span range helps in the selection of appropriate materials and the design process, ensuring safety and performance standards are met.
