TADAS dampers, friction dampers and viscous dampers are passive energy dissipation systems that Part Saze Co. uses for the passive control of structures.

TADAS dampers, friction dampers and viscous dampers are new emerging passive earthquake energy dissipation systems that have numerous advantages for different types of structures. These dampers can use in low to high rise structures with different types of lateral load resisting system such as moment resisting frame, shear wall resisting frame, braced frame and etc. Some of the most important benefits of these dampers are listed below:

  • Enhance the safety level of structures by decreasing the damage due to earthquake in primary elements.
  • Upgrade the performance level of structures by reducing the absolute accelerations and interstory drifts.
  • Relieve the time and the cost of repairs after an earthquake due to less damage occurrence in primary elements at a structure equipped dampers.
  • Decrease the total cost of construction. According to building codes such as ASCE, EC and etc. and by noting the dissipating nature of dampers the design lateral load can be reduced. This reduction leads to smaller section for most of structural primary elements and this means lower cost for construction. But at this point the cost of damper individually is an important factor and with using the expensive dampers it may the total cost of construction increases.
  • Decrease the size of primary elements section of structure due to reduction in design lateral load. This is a very important option that TADAS damper brings to a structure. By reducing the size of beam and column sections the total height of structure is reduced and net area in floors is increased respectively.

TADAS damper is manufactured by Part Saze Co. with relative low cost during an exact and sensitive procedure and using high accuracy devices. Part Saze TADAS dampers are tested in BHRC – Building and Housing Research Center – of Islamic Republic of Iran and passed all of the related codes regulations.
