Advanced numerical modelling and development of design rules for novel demountable steel-concrete composite bridges

PHD项目将在ABAQUS中开发先进的有限元模型，以在实验室重现全尺寸试件(例如，10米跨度的钢-混凝土组合桥)的复杂非线性行为。校准后的模型将用于：(I)进一步了解新部件的局部性能；(Ii)优化其结构细节；以及(Iii)评估它们对组合桥梁短期和长期性能的影响。此外，将进行参数数值模拟以扩大现有的实验数据库，并将使用正式的统计方法在欧洲法规4的框架内制定可靠的设计规则。最后，该项目将进行现实的桥梁设计和寿命周期成本评估研究。

The PhD project will develop advanced finite element models in ABAQUS to reproduce the complex nonlinear behaviour of full-scale specimens (e.g. 10 m span steel-concrete composite bridge) in the laboratory. The calibrated models will be used to: (i) gain further insight in the local behaviour of the new components; (ii) optimise their structural details; and (iii) assess their effect on the short-term and long-term behaviour of composite bridges. Moreover, parametric numerical simulations will be conducted to expand the available experimental databank and formal statistical methods will be used to develop reliable design rules within the framework of Eurocode 4. Finally, the project will conduct realistic bridge design and life cycle cost assessment studies.
