The slurry wall, piles, and foundation are integrated into a type similar to that of a 公尺，C1 ／ D1 聯合開發大樓地下
caisson foundation. A three-dimensional equivalent spring is utilized to simulate
the soil-structure interaction, and the deformation and stress are assessed under
various load combinations to ensure the safety of the existing foundation and piles.
The Taipei Corridor, defined as the historical axis of Taipei Castle, located on
complex underground structure surrounding the site. As a result, certain steel
columns are situated above the underground railway tunnel. To overcome this
challenge, a long-span transfer steel girder is utilized to span the tunnel. The north
side of the girder is connected to the existing exterior wall of the basement, while
the south side rests on a new foundation, which does not come into direct contact
with the tunnel. This configuration transfers the load of the steel column to both
ends, ensuring the safety of the tunnel.
The C1/D1 Joint Development Building represented a highly complex and
challenging project that required constant communication and collaboration among
team members in order to develop reliable structural design strategies. Through
innovative and rigorous structural design, the new and existing structures are
integrated to ensure the safety of the entire building.
