【Abstract】 The natural vibration characteristics and kinetic response due to an earthquake of 7 magnitude of the buildings for the Three Gorges Project are analyzed and calculated with the finite element method. Different schemes of technical design and all important influencing factors are analyzed and compared and kinetic optimization design is performed by referring to the characteristics of natural vibration and the control indices for dynamic displacement and dynamic stress, providing theoretical basis for the earthquake resistance design.更多还原
