As the vertical cylindrical storage tanks need to site construction, which in appearance and structure design to achieve economical and pay attention to the natural environment of the storage tank storage tank suffered the impact of the design process to be enhanced, to reach wind, snow, earthquake, etc. role. This tank wall structure using ladder-type tank wall, tank bottom edge of plate with circular tank bottom set, tank top with dome structure. Storage medium according to the requirements of the selection of vertical cylindrical tanks, the media in this article for the kerosene tank, tank with Q235A steel. According to the construction site environmental requirements and tank steel, body thickness and othe
