| 標(biāo)題 |
| 高速鐵路先、后張預(yù)應(yīng)力混凝土簡(jiǎn)支箱梁力學(xué)效應(yīng)對(duì)比分析(25 卷) |
| 英文標(biāo)題 |
| Mechanics Effect Analysis of Pre-tensioned and Post-tensioned Pre-stressed Concrete Simply-supported Box Beams on High-speed Railway |
| 摘要 |
| 通過有限元分析技術(shù)，以24 m跨度先、后張梁為分析對(duì)象，使用SAP93靜、動(dòng)力通用分析軟件建立8節(jié)點(diǎn)塊體元力學(xué)模型，對(duì)先張混凝土箱梁進(jìn)行應(yīng)力、剛度、剪力滯后、畸變、翹曲、支座脫空效應(yīng)、局部效應(yīng)等力學(xué)性能分析，并重點(diǎn)與后張梁的力學(xué)性能進(jìn)行對(duì)比。結(jié)果表明：先張梁與后張 |
