1973年Wolf论述了一种大网架的分析法。分析是非线性的,正如Bleich所述的那样,把杆件的非线性后期压曲性能都考虑进去了,并且采用了Zienkiewicz提出的“初始应力”法。大多数研究人员由于使用了Wolf的类似方法,有的简化了杆件特征,而有的则增大了杆件特征的复杂化。所有的方法都有其共同的计算特点,即杆件特征是线性的,解题的方法都 In 1973 Wolf discussed a large network analysis method. The analysis is nonlinear and, as Bleich stated, takes into account the non-linear postbuckling properties of the bar and uses the “initial stress” method proposed by Zienkiewicz. Most researchers use Wolf’s similar methods, some simplifying the bar features, while others increase the complexity of the bar features. All the methods have their own common computing characteristics. That is, the bar features are linear, and the methods for solving problems are all
