| 摘 要： | 简支梁桥桥面连续构造的早期损坏,是由设计和施工中诸多不合理因素引起的.笔者根据有限元理论,借助ANSYS工作平台,对简支梁桥桥面连续构造在沥青砼铺装层重量、活载以及温度作用下的受力状况进行了空间非线性分析,并依此提出了预防对策及改善措施.

The space simulation analysis of simply-supported girder briges with continuous slab-decks |
| |
| Abstract: | The early stage damages of simply-supported girder bridges with continuous slab-decks are due to many unresonable factors in design and construction. According to the finite element theory and applying ANSYS, the mechanical behavior of simply-supported girder bridges with continuous slab-decks under weight of the asphalt concrete surfacing, live load and temperature variation has been analyzed nonlinearly. And some precautionary and improving measures are suggested accordingly. |
