Precast concrete structure having light weight encapsulated cores |
摘要 |
A precast concrete bridge system containing one or more sections wherein each section includes a horizontally disposed, load-bearing span that is integrally cast with a pair of vertical side walls. Each wall contains lightweight cores encapsulated in the concrete to create a series of longitudinally extended beams in each wall so that the beams in one wall are coaxially aligned with the beams in an adjacent wall. The cores constitute between 16-35 % of the total section volume.
