对网壳杆件计算长度确定方法进行了总结,对压杆计算长度的现有研究进行了综述.结合一单层球面网壳,利用有限元分析方法对网壳杆件的计算长度进行了计算,并与规范取值进行了比较.提出了一种改进的杆件计算长度确定方法,并对同一单层网壳进行了计算对比,结果表明改进的网壳杆件计算长度确定方法能够较为便捷、精确地确定每根杆件的计算长度.对于其他类型的结构,该方法同样可以方便地确定压杆的计算长度.
The method to determine the length of the shell pieces is summarized and the existing research on the calculation of the length of the pillars is reviewed.With a single-layer spherical reticulated shell, the calculated length of the shell pieces is calculated by finite element method , And compared with the standard values.An improved method of calculating the length of the bar is proposed and the same single layer reticulated shell is calculated and compared.The results show that the improved method of determining the length of the reticulated shell can be more convenient , To accurately determine the calculated length of each rod.For other types of structures, this method can also easily determine the calculated length of the strut.
