Special designed structures for earthquakes and cyclones

Below a picture compliation of structures designed by our company which sustained earthquakes and/or cyclones.  

EARTHQUAKE RESISTANCE (*)  

 Bali villa 5 Iris p1  DSCN8430 
Designed to Richter 7.5 (was full scale tested in 2017 by a 6.9 earthquake). No damages  Designed to Richter 6.0 (was full scale tested in 2019 by a 5.2 earthquake). No damages    Roof design to withstand a Richter 6.5 earthquake. Not yet full scale tested  


CYCLONE RATED (*)       

 Center roof structure  DSCN5443 Sedap malam p5 
 St. Maarten (hurricane 5)  Philippines (cyclone 5+) Guadeloupe (hurricane 5)
 Cyclone resistant truss structure p1a   DSCN5787   Bunga Kamboja p1
Typical cylcione rated roof design for large sized dwellings  S. Africa (hurricane 3)  Sta. Lucia (hurricane 4)


(*) For specific areas where earthquakes and/or cyclones occur our designs include all parameters required for the calculation of the soil movements caused by earthquakes and the extremely high material stresses caused by wind, whereas the structure should survive these phenomena. However, these parameters are based on international codes developed by institutions which have decades been involved in the study of the physical behaviour of earthquakes and cyclones Unfortunately nature is unpredictable and despite the application of the parameters in our calculations no guarantee can be given that zero damages will occcur.

Prefab World Bali

Reviews from Prefab World Bali

On November 7, 2013 typhoon Haiyan, known as typhoon Yolanda in the Philippines, was the second deadliest on record that hit the archipelago killing over 4,000 peoiple which we deeply regret. The system's one-minute sustained winds reached to 315 km/h (196 mph), unofficially making Haiyan the 4th most intense tropical cyclone ever observed and made it the strongest tropical cyclone to make landfall on record. Our engineering department designs our units in cyclone areas to cyclone rating and have added a 10% additional wind force to the general cyclone design codes to cope with global warming, introducing stronger cyclones in the future. Our unit A-2 sustained typhoon Haiyan and survived. This is what the owner wrote us:
"There were minor damages and the roof remained fully in tact. Your clients should know though that this house was properly designed and built with typhoons in mind. Good job Prefabworld Bali International".
