bridge slab
Examples
- Nonlinear fem analysis for the concrete bridge deck slab
混凝土桥面板的非线性有限元分析 - This paper highlights the durability design features and design alternative adopted for the parts of steel structure , concrete decks of and joints between steel and concrete composite box girder for the cable - stayed spans of donghai bridge over main navigable channel in the marine environment
摘要介绍东海大桥主航道斜拉桥钢混凝土箱形结合梁的钢结构部分、混凝土桥面板、钢混凝土结合部位在海洋环境下耐久性设计特点及采用方案。 - Before studying the concrete composite deck pavement , we introduce the basic theory of touching analysis , and come up with the realization of touching analysis in the fem analysis considering the touch of concrete bridge cover plates , asphaltum concrete overlay with bridge cover etc . connect with the experiment on the spot of bridge , the software ansys is used to solidity modeling and analyzing an assembly simply supported bridge before adding overlap , after adding overlap etc . , and study the influence of adding overlap on the underside bridge structures
在进行装配式混凝土简支板桥复合铺装结构的探讨性研究前，先介绍了接触分析基本理论，并提出了考虑混凝土桥面板板间接触、沥青混凝土加铺层与桥面接触等接触分析在有限元分析中的实现思路。结合一座装配式简支板桥现场试验数据，采用ansys对该桥在加铺前后进行了实体建模与计算分析，讨论了沥青混凝土加铺层对下部结构物的影响。 - The author advances that the shear connector is simulated by two spring elements , which are vertical to each other and parallel to the interface between steel and concrete , and one multipoint constraint element , mpc element , which is vertical to the interface . the author also puts forward that the crack of the deck is simulated by the gap element which ca n ' t support longitudinal tensile force but can support longitudinal compressive force
提出了以正交的两个平行于钢和混凝土界面的弹簧单元及一个垂直于界面的多点约束( mpc )单元来模拟剪力键，以小间隙接触( gap )单元来模拟混凝土桥面板的开裂，模型中忽略了混凝土板与钢梁接触面间由摩阻而产生的粘着力。
