WORLDDOMEHOUSE is safe as it implements the dome shape which is structurally safe.
WORLDDOMEHOUSE is structurally designed to endure more than 2 meter of snowfall, 40m/s of strong wind and 5.5 magnitude of earthquake on the Richter scale.

WORLDDOMEHOUSE uses WORLDDOMEHOUSE wall panel which is developed is house. Strength properties of WORLDDOMEHOUSE wall panel are as follows.

Structural analysis

In order to study the structural stability of WORLDDOMEHOUSE that uses high-density EPS, MIDAS-GESw, a proven software by Computational Structural Engineering Institute of Korea is used as a system for general purpose structural analysis and optimized design in construction areas. After 3D dynamic analysis based on the finite element method was performed using MIDAS-GESw, members were designed through allowable stress design method. Specifications and standard strengths of t he materials which were used for structural analysis are shown in the following table

Specifications and standard strengths of materials for structural analysis

Applicable loads include dead load, snow load, seismic load, wind load, etc. which are calculated in accordance with [Load standard and interpretation of construction structures] established by Architectural Institute of Korea; and regarding dead load, construction load was added considering the working conditions during the construction.

Design load requirement

• Dead load
  • Dead load : 140N/㎡
  • Construction load : 500N/㎡

• Snow load
  • Based on 2 meters of snowfall
  • No snow removed by wind; considering the snow slides due to the slope

• Wind load
  • Basic wind speed V=40m/sec (based on the construction structure standard(Architectural Institute of Korea, 2009))

Results of stress analysis

DL : Dead Load, SL : Snow Load
WL : Wind Load, EL : Earthquake (seismic) Load

Since the combined stress value of dead load, snow load, wind load, seismic load, etc., is within the range of the long-term allowable stress of 0.09MPa, high-density EPS dome house is structurally safe.
