本文从Ritz的振型组合法出发,分析了影响坝上附属建筑物地震荷载的主要因素。建议了坝上附属建筑物地震荷载的简化计算公式。也给出了计算附属建筑物地震荷载必要的辅助数据并讨论了坝上附属建筑物的合理设计。
In this paper, starting from Ritz’s modal combination method, the main factors that affect the seismic load of ancillary buildings on the dam are analyzed. A simplified calculation formula for the seismic load on the appendage of the dam is proposed. The necessary auxiliary data for calculating the seismic load of ancillary buildings are also given and the reasonable design of the ancillary buildings on the dam is discussed.
