Reduced Sloshing Effect in Steel Tanks
How to effectively reduce the sloshing wave height of the liquid is an important direction for the optimal design of the steel liquid storage structure. To find the optimal design for structure with reduce liquid sloshing, the liquid–solid coupling seismic responses of steel rectangular water purification structure (SRWPS) under different opening arrangements in a partition are studied. Based on the finite element method, the arrangements of the No. 11 partition with 2, 4 and 6 holes are selected as the parameters to study how the variation of liquid sloshing wave height, the wall displacement and the stress change with the number of holes in the partition. The results show that the liquid sloshing height is significantly reduced and the deformation of the wall of SRWPS is small when the partition plate with holes compared to non-perforated partitions. With the increase of holes in the No. 11 partition, the magnitude of the principal stress shows an increasing trend. This means that the tensile strength of the partition itself needs to be focused on when designing the openings of a partition to avoid tensile damage to the partition. However, when the number of partition openings is controlled in a certain range, the overall strength of the structure is less affected due to the synergy of functional partition and perforated baffles. The 4-hole layout scheme of the No. 11 partition is the best solution to reduce liquid sloshing, as determined by comparing the liquid sloshing wave height, the wall deformation, the stress state and the partition displacement of SRWPS under different opening schemes. The hole layout scheme proposed by this paper provides a new perspective for the SRWPS reducing sloshing analysis.
