This roof is self-supporting and is free of internal structural members for ease of maintenance and painting.Plates are butt welded or lap welded and are supported directly on the top angle,compression ring or shell plate.Internal structural stiffeners may be used on large diameter roofs to avoid excessive plate thickness.OptionsDESIGN RECOMMENDATION FOR STORAGE TANKSgases,and under-ground tanks for the storage of water and oil.The trend in recent years is for larger tanks,and as such the seismic design for these larger storage tanks has become more important in terms of safety and the environmental impact on society as a whole.DESIGN RECOMMENDATION FOR STORAGE TANKSgases,and under-ground tanks for the storage of water and oil.The trend in recent years is for larger tanks,and as such the seismic design for these larger storage tanks has become more important in terms of safety and the environmental impact on society as a whole.
