| 標(biāo)題 |
| 分離模型預(yù)應(yīng)力混凝土梁數(shù)值模擬(51 卷) |
| 英文標(biāo)題 |
| Numerical simulation of separation model of prestressed concrete girder |
| 摘要 |
| 運(yùn)用ANSYS進(jìn)行空間曲線布筋的變截面預(yù)應(yīng)力混凝土梁在靜力荷載作用下的有限元全過(guò)程分析，并將計(jì)算結(jié)果與試驗(yàn)結(jié)果相對(duì)比。結(jié)果表明，數(shù)值模擬的荷載撓度曲線與試驗(yàn)結(jié)果吻合較好，此外計(jì)算的混凝土梁頂應(yīng)變以及中和軸位置變化也較好地符合了預(yù)應(yīng)力混凝土梁靜載過(guò)程中的變化，說(shuō) |
