Stress analysis of horizontal containers
Thread Content
Encountered this question: Force analysis of a horizontal container? From which aspect should the answer be given: the applied loads (internal or external pressure during operation, seismic loads, support reactions, pressure test conditions) or those nine forces? Everyone, please share some good suggestions; this way we’ll have a clear idea next time we encounter similar problems. Thank you
Personally, I think that for internal pressure, it is necessary to first verify the strength of the cylinder and the head. During verification, analysis is conducted separately for the design conditions, test conditions, and operating conditions. Additionally, earthquakes and snow loads must be taken into account. At the same time, equipment instability should also be checked, that is, the collapse due to bending at the middle that may occur when the span of the equipment’s saddle is too large. A similar problem exists for external pressure as well. Additionally, it is also necessary to check whether the strength of the saddle is sufficient and whether the span is appropriate.
It should be answered based on the shear diagram, bending moment diagram of the saddle, as well as axial stress, circumferential stress, and shear force.
