中文摘要: |
现代桥梁跨径不断增大,宽度也在不断加宽,受力条件愈来愈复杂,其表现的空间效应越来越明显,单纯的由平面分析很难反应桥梁的实际受力情况。运用实体退化单元对杭州市文晖路立交桥主桥(斜拉桥)进行了其三维空间分析,特别分析了主梁纵、横向的正应力和索塔竖向正应力。分析结果表明该桥的空间效应比较明显,在恒载作用下桥梁的受力比较合理。 |
英文摘要: |
The modern bridge structure become more complex. Its three\|dimensional effect is very obvious, and the result of planar analysis can hardly describe the real stress of bridge. Degenerated solid element was applied to analyze WenHui Bridge to know its spatial stress state. The result of analysis shows the spatial effect is very obvious. And its stress state is reasonable. |
