摘　　要： 针对嵌筋加固古砖塔的配筋构造和结构性能,依据配筋砌体结构的力学原理,提出了古塔偏心受压抗震验算方法。考虑古塔的尺度、材料性能以及嵌筋工艺的特征,给出了抗震验算方法的基本假定,确定了附加偏心距、承载力抗震调整系数的取值。基于工程应用,建立了古塔矩形、圆形截面的抗震验算公式,对六边形和八边形的古塔截面,给出了简化为矩形或圆形截面的几何方法。 Aiming at the reinforcing construction and structural property of ancient masonry pagoda reinforced by embedded steels, and based the mechanics principle of reinforced masonry structure, a seismic analysis method for eccentric compression capacity of the pagoda is proposed. This method considered dimension and material property of masonry pagoda as well as the characteristic of the embedded steels technology, given the basic assumption of seismic analysis method, and determined the value of addition eccentric distance and the modified coefficient of seismic capacity. On account of engineering application, the seismic analysis formulas for rectangle and circular cross section of pagoda has been established, and the geometry method simplified to rectangle or circular cross section for hexagon and octagonal section of pagoda has been also provided.
