铰结排架是一种使用很广的结构形式,这类结构横向地震荷载的计算较麻烦。按照现行的抗震规范TJ11-78,这类结构横向抗震计算中工作量最大的是确定排架的基本周期,特别是二阶柱和组合砖柱时。本文通过对地震荷载计算公式的整理及合并,提出了计算等高砖排架横向基本周期和地震弯矩(排架柱的截面强度是由弯矩控制的)的简化公式和相应的表格。本文公式稍经变换,就可方便地用于钢、钢筋混凝土及绍合砌体等一切能够简化为单质点体系的建筑,如高架水塔等。
The articulated truss is a widely used structural form, and the calculation of lateral seismic load of such structures is more troublesome. According to the current seismic code TJ11-78, the largest workload in this type of structural lateral seismic calculation is to determine the basic period of the truss, especially the second-order column and the combined brick column. In this paper, through the consolidation and consolidation of seismic load calculation formulas, the simplified formulas and corresponding tables for calculating the basic transverse period of the contour brick briquette and the seismic bending moment (the section strength of the stud columns are controlled by the bending moment) are proposed. With a slight transformation of this formula, it can be easily applied to buildings that can be reduced to a single-mass system, such as elevated water towers, etc., such as steel, reinforced concrete, and masonry.
