(鄭州工業(yè)大學(xué) 450002)[提要] 預(yù)應(yīng)力雙曲拋物面索網(wǎng)因其幾何非線性而使精確求解困難。作者將配線法與Galerkin法結(jié)合使用計算該類具有復(fù)雜底平面的索網(wǎng)結(jié)構(gòu)。該方法考慮索網(wǎng)結(jié)構(gòu)特點配線,同時以基函數(shù)為權(quán)函數(shù)提高分析精度。與其它加權(quán)殘數(shù)法比較,該方法簡便實用而較適于索網(wǎng)結(jié)構(gòu)。算例表明結(jié)果可靠。

In consideration of characteristic of the structures, as weighting function the basis function is adopted in the collocation line method. The approximate fomula is simple and efficient in comparision with the results computed by other method of weighted residuals.
Keywords: hyperbolic paraboloid cable network; collocation line; galerkin-method
