| 預(yù)應(yīng)力空心板梁橋材料非線性性能研究(49 卷) |
| 英文標(biāo)題 |
| Study on non-linear property of materials used in prestressed hollow slab girder |
| 摘要 |
| 在預(yù)應(yīng)力空心板實(shí)橋破壞性試驗(yàn)的基礎(chǔ)上，考慮材料非線性的影響，利用通用有限元軟件ANSYS建立了預(yù)應(yīng)力空心板橋梁有限元模型。計(jì)算分析了這類橋梁的撓度和應(yīng)力變化規(guī)律，并與破壞性試驗(yàn)實(shí)測結(jié)果進(jìn)行對比。結(jié)果表明，非線性計(jì)算結(jié)果與試驗(yàn)結(jié)果吻合較好，應(yīng)用非線性有限元法能夠 |
