摘　　要：提出了在配筋砌块结构中使用的阶谱块体单元法。首先,给出形函数矩阵,讨论位移模式、几何方程和本构方程的具体形式;然后,根据虚功原理导出平衡方程并给出刚度矩阵的表达式;最后,有配筋情况下,实现配筋刚度矩阵与整体刚度矩阵的集合。运用所提方法分析了一个算例,从而验证了其正确性和有效性。所提方法具有前处理简单、计算精度高等特点,具有广阔的应用前景。A hierarchical block element method for reinforced block structure is developed. First, a shape function matrix is given and the patterns of displacement, geometric equation and constitutive equation are discussed; then, according to the principle of virtual work, the equilibrium equation and the expression of stiffness matrix are deduced; finally, the reinforced stiffness matrix is collected with the overall stiffness matrix. Applying this method to an example, its correctness And effectiveness are verified. This method is simple, accurate, and so has the wide application orospects.
