It's hard to miss Reston Station, a 371,000-square-foot, mixed-use building near outside of Washington, D.C., thanks to its unique lateral system consisting of architecturally exposed concrete in the lobby and in the exoskeleton columns on the building's east and west sides.
We provided structural design services to Jahn for the building, which was completed in 2017.
- The building consists of 16 levels of above-grade office space constructed with post-tensioned, two-way concrete slabs with 15-foot cantilevers and 40-foot spans. The design also includes an open plaza surrounded by five-story concrete and steel composite columns.
- The structural and architectural layouts, which included an imbalance in the number of sloping interior columns in each direction, required our team to perform a staged construction analysis to determine whether the building movement was within tolerance.
- The analysis revealed that the top of the building would move outside of acceptable degrees under its self weight, so the team directed the contractor to place all columns along their theoretical centerline to correct for any lateral displacements during construction.
