설계 변수 변화에 따른 LNG 저장탱크 Steel Roof 거동 분석

This paper deals with parametric studies for the structural response of LNG Storage Tank steel roof behavior acoording to change in design condition. In the design of steel roof, it may be required to represent a stable behavior under many loading conditions and those of combinations. We fulfill the analysis the steel roof behavior during concret placing and additionally change the design variabls like H beam, pressure and steel roof plate thickness. On the basis of the obtained frsults from this studies a guideline for a more reasonable design of LNG storage tank steel roof is introduced.
