【提要】通過千斤頂對索網(wǎng)施加預應力后，索網(wǎng)中預應力分布是已知的。如果邊界結構的剛度相對懸索不是無限大，就必須考慮邊界結構變形的影響。針對這一情況，提出一種采用大型通用有限元軟件ANSYS進行建模的方法。兩個算例的計算結果表明，方法是正確的，且操作方便、快捷，可以滿足實際工程的需要。
【關鍵詞】 ANSYS 索網(wǎng) 有限元建模 彈性邊界結構
Modeling Analysis of Cable Networks with Flexible Supports/Chen Bilei, Nie Jianguo(Department of Civil Engineering,Tsinghua University,Beijing 100084,China)
Abstract:When prestressed,the cable networks deform together with flexible supports.The
error will be noticeable without considering the effects of flexible supports.The objective is to present a novelty modelling method using commercial FEA software ANSYS.The results show that the method proposed is accurate and convenience.
Keywords:ANSYS; cable networks; finite element modeling; flexible supports
