Abstract
Similar to Chapter 6, this chapter presents illustrative examples of finite element models developed to understand the structural behavior of steel-concrete composite bridges. The examples are based on the layout, loading, and design background presented in Chapters 1–4Chapter 1Chapter 2Chapter 3Chapter 4 as well as based on the finite element modeling background highlighted in Chapter 5. This chapter is initiated by a brief introduction followed by a review of recent investigations reported in the literature concerning the modeling of steel-concrete bridges. This chapter details how the finite element models were developed and the results obtained. The presented examples show the effectiveness of finite element models in providing detailed data that complement scarce experimental data in the field. The results are discussed to show the significance of the finite element models in predicting the structural response of the different steel-concrete composite bridges investigated. In overall, it is aimed to show that finite element analysis not only can assess the accuracy of the design rules specified in current codes of practice but also can improve and propose more accurate design rules. It should be noted that the main issues that differentiate between the finite element models presented in Chapter 6 and those presented in this chapter are the presence of reinforced concrete slabs and shear connections. The finite element models addressed in this chapter will detail how the aforementioned issues are dealt with in the models based on the material properties highlighted in Chapter 2, the design rules highlighted in Chapter 3, and the finite element modeling variables presented in Chapter 5. The author hopes that the review of recent finite element models reported in the literature together with the illustrative finite element models developed by the author in this chapter can provide readers with a complete piece of work regarding the finite element analysis of steel-concrete composite bridges.
