Smile frame (seismic strengthening)

This method of seismic reinforcement (smile frame) makes use of a reinforced frame of tensioned precast concrete with PC steel rods arranged diagonally within the plane of the structure which is joined to the existing building using steel pipe cotters of pressure bonding and post-installed anchors.


Smile frame key features

  • Construction does not require an interior layout and can be carried out while the building is still being occupied.
  • Because the PC steel members are thin, the frame does not interfere with ventilation, natural illumination or the view of the outside.
  • Because PCa members are used, the construction period is shorter, involves less noise and produces high quality.
  • Smaller members means reduced cost.
