under working loads, the distribution of moments in astatically indeterminate structure is based on elastic theory and the whole structure remains in the elastic range.
依据工作负荷,在一个时辰的超静定构造散布,弹性理论和整个构造的根底依然在弹性规模内。
a method to use the function of excel layout evaluation to calculate statically indeterminate structure problem was introduced in this paper.
