Abstract

The practical application of high-position fire-fighting water tanks on the top-level of office buildings in State Grid Corporation of China is studied in this article. Fluid-solid-coupling mathematic models were established based on ABAQUS finite element analysis software to compare the calculational results in two-dimensional situations and three-dimensional ones. Meanwhile, a 22-storey frame-shear wall structure named Innovation Mansion was selected to discuss the vibration reduction effect of TLD. The results indicate that the fliud-solid-coupling analytical method could reflect the nonliear character of TLD-structure systerm precisely, and the aseismic ratios were 2%~5% variation between two-dimensional models and three-dimensional ones. The TLD has positive effects on controlling the structural seismic responses and the aseismic ratios could reach 10% around, besides, the TLD damping force not only offset the increased base-shear arose from its own weight, but also reduced the total base-shear.
