Progressive Collapse

Joints between panels are tied together using pre-shuttered insitu-fill to create a robust joint with minimal finishing required. The joints use wire ties designed to meet the specific tie-force criteria, but also to allow flexibility in assembly tolerances during erection.

Peripheral and internal ties use high strength steel strand within the nominal insitu joints at cross-wall locations and around the perimeter of the building to create a continuous tie arrangement.

Building design is analysed for structural stability by Precast Structures consultants who have extensive knowledge in the design stability of cross-wall building structures.
