柱点支承螺栓球网架结构自重估算研究

Research on Self Weight Estimation of Bolt Sphere Grid Structure with Column Point Support

随着我国钢结构工程的迅速发展,网架结构得到了广泛的应用。针对柱点支承网架,依据现行规范中给出的自重估算公式,对公式的适应性进行了分析,并在回归分析的基础上,对网架自重估算公式进行修正。通过公式修正,提高规范中网架自重公式估算的准确性,也为相关规范的修订提供一定的参考依据。

With the rapid development of steel structure engineering in China,grid structure has been widely used.According to the self weight estimation formula given in the current code,the adaptability of the formula is analyzed,and the self weight estimation formula of the grid is modified on the basis of statistics and regression analysis.Through the correction of the formula,the applicability of the self weight estimation formula of the grid structure in the code can be improved,and it can also provide a certain reference basis for the revision of relevant codes and regulations.
