Abstract

A procedure for evaluating cost-effectiveness of seismically isolated pool structures is presented. The ground motion is modeled as the spectral density function matching the response spectrum, which is specified in codes in terms of acceleration and site coefficients. Interaction between flexible walls and contained fluid is considered in the form of added mass matrix. The thickness of wall and the stiffness of isolator are used as main design variables while the minimum cost for comparison is estimated. Transfer function vector of the system is derived and spectral analysis method based on random vibration theories is used for calculating probability of failure. Evaluation results of the examples show that the cost-effectiveness of seismically isolated pool structures is relatively high in regions of low to moderate seismicity.
