Abstract
Instability of structures, such as large vertical pressure vessels, is always an issue under the seismic load. In this current work, the acceleration that causes instability for a vertical pressure vessel has been determined experimentally using scaled models. This instability is caused by the tipping of the tall structure that is not completely fixed to the ground. This method is applied for three different sizes of pressure vessels, representing 50 CuFt to 1100 CuFt full scale models. These experimental results are compared with theoretical models. Using dimensional analysis, the accelerations that will cause the instability in the actual full-size models are estimated. By comparing the acceleration needed to cause instability in the full-scale model and actual earthquake data, the failure rate of the vertical pressure vessel is evaluated with respect to top twenty worldwide seismic events. Based on the prediction we can suggest if additional damping or bracing systems are needed to ensure that failure does not occur. This experimental procedure will help to determine the stability of special types of structures under earthquake loading.
