Abstract
This paper describes the details of the seismic analyses undertaken to retrofit the Kersland drinking water reservoir in Vancouver, British Columbia, Canada. The reservoir has a storage capacity of about 67 million litres, measures approximately 100 m by 150 m, and is partially buried. The walls are supported by above-ground soil berms. Seismic upgrading of the reservoir required an assessment of the loads imposed on the perimeter walls of the reservoir due to the design seismic event. The problem of soil-structure and structure-fluid interaction during seismic loading is complex, and could significantly increase the lateral forces on the reservoir wall. Seismic response analysis of the soil-structure system was carried out using the finite element program FLUSH. Modeling the effects of water under earthquake loading was included as convective and impulsive forces using a series of lumped masses attached to selected structural beam element nodes and a horizontal spring. The bending moments and shear forces in the reservoir wall, and seismic earth pressures exerted by the soil on the wall were obtained for detailed structural analyses. The results of FLUSH analyses were compared with the available closed-form solutions.
