進行池狀結構之耐震評估與分析程序時，須先估算其所須考慮的靜載重、活載重、土壤載重、流體載重、溫度載重及地震載重，其中地震載重又可分成地震引致流體動態載重、土壤動態載重及構體本身之地震力等，而地震引致流體之動態載重又可分成流體衝擊模態載重、流體對流模態載重、流體垂直振動引致之水平動態載重等；其次，地震引致土壤之動態載重又可分成土壤主、被動土壓力等；另外，池狀結構構體本身亦應考慮其垂直地震力及池牆本身之側向慣性力。本研究針對國內常見的池狀結構的載重需求估算方式與耐震評估流程進行研討，俾使其耐震評估與分析程序更加完備。

When carrying out the seismic evaluation and analysis procedure of the liquid storage tank, the static load, live load, soil load, fluid load, temperature load and seismic load must be estimated first. The seismic load can be divided into earthquake-induced fluid dynamic load, dynamic load of the soil and the seismic force induced by the self-weight of the structure. Firstly, the dynamic load of the fluid caused by the earthquake can be further divided into the fluid impulsive modal load, the fluid convective modal load, and the horizontal dynamic load caused by the vertical vibration of the fluid. Secondly, the soil dynamic load caused earthquakes can also be divided into active soil pressure and passive soil pressure. In addition, the vertical seismic force of the liquid storage tank and the lateral inertial force of the tank wall should also be considered. This study focuses on load demand assessment methods and seismic evaluation process for the common pool-like water tank structure in Taiwan to make the seismic evaluation and analysis procedures more feasible and reasonable.
