“…The steel girders are placed on the head of the piers without any propping; subsequently, the slab is concreted and the continuity of the composite beam is completed by concreting the beam joints and the transverse beams over the pier. This kind of joint has been studied in the past but only for static load conditions, [4][5]. In this paper, the results of the performance-based earthquake engineering (PBEE) analysis, carried out to assess the seismic performance of short-medium span steel-concrete composite I-girder bridges, are presented and dis-cussed.…”

In this paper, the results of the performance-based earthquake engineering (PBEE) analysis, carried out to assess the seismic behaviour of short-medium span steel-concrete composite Igirder bridges, are presented and discussed. The selected case study is part of a group of bridges analysed within the SEQBRI project, funded in 2012 by the European Union, which deals with a systematic development of the PBEE analysis for short-medium span steel-concrete compo-site I-girder bridges. In this respect, fragility and damage analysis of the selected bridge are performed using a proper component-based numerical model along with wide experimental campaign. These outcomes are then integrated in the decision-making analysis, where the selected decision variable is the repair cost ratio of the bridge. The results show the good performances of short medium span steel-concrete composite bridges, both for minor and major damage scenarios.

“…A new type of beam-to-beam joint used to connect continuously composite beams in small and medium span bridges was proposed by Somja et al (2012). The proposed joint was realized by encasing totally the two composite beam ends into a massive composite reinforced concrete block.…”

This article discusses the non-linear analysis and design of highway composite bridges with profiled steel sheeting. A three-dimensional finite element model has been developed for the composite bridges, which accounted for the bridge geometries, material non-linearities of the bridge components, bridge boundary conditions, shear connection, interactions among bridge components and bridge bracing systems. The simply supported composite bridge has a span of 48 m, a width of 13 m and a depth of 2.3 m. The bridge components were designed following the European code for steel–concrete composite bridges. The live load acting on the bridge was load model 1, which represents the static and dynamic effects of vertical loading due to normal road traffic as specified in the European code. The finite element model of the composite bridge was developed depending on additional finite element models, developed by the author, and validated against tests reported in the literature on full-scale composite bridges and composite bridge components. The tests had different geometries, different boundary conditions, different loading conditions and different failure modes. Failure loads, load–mid-span deflection relationships, load–end slip relationships, failure modes, stress contours of the composite bridge as well as of the modelled tests were predicted from the finite element analysis and compared well against test results. The comparison with test results has shown that the finite element models can be effectively used to provide more accurate analyses and better understanding for the behaviour and design of composite bridges with profiled steel sheeting. A parametric study was conducted on the composite bridge highlighting the effects of the change in structural steel strength and concrete strength on the behaviour and design of the composite bridge. This study has shown that the design rules specified in the European code are accurate and conservative for the design of highway steel–concrete composite bridges.

“…Haensel (1998) presented results of a research program sponsored by steel fabricator ARBED, which built bridges with an innovative type of connection for composite steel and concrete girders, where the bending moment of the supports at the top flange was transmitted across the bearings by the tensile reinforcement alone, while the bending moment in the bottom flange was transmitted by means of a couple of compression plates through the concrete. Contemporarily to Haensel (1998) and Svadbik and Strasky (1998) presented the "Modular Span Multi-Cell Box Girder System" for short span (from 6 to 30 m) steel bridge structures. The bridge deck was composed of steel modules and a composite concrete deck slab.…”

a b s t r a c tIntegral abutment bridges are becoming rather common, due to the durability problems of bearings and expansion joints. At the same time, among short-and medium-span bridges, multi-beam steel-concrete composite deck with hot-rolled girder is an economical and interesting alternative to traditional pre-stressed concrete solutions. The two concepts can be linked together to design integral steel-concrete composite bridges with the benefits of two typologies. The most critical aspect for these bridges is usually the joints between deck and piers or abutments. In this paper, an innovative beam-to-pier joint is proposed and a theoretical and experimental study is introduced and discussed. The analyzed connection is aimed at combining general ease of construction with a highly simplified assembly procedure and a good transmission of hogging and sagging moment at the supports in continuous beams. For this purpose, the traditional shear studs, used at the interface between steel beam and upper concrete slab, are also used at the ends of steel profiles welded horizontally to the end plates. To better understand the behaviour of this kind of joints and the roles played by different components, three large-scale specimens were tested and an FE model was implemented. The theoretical and experimental results confirmed the potential of the proposed connection for practical applications and indicated the way to improve its structural behaviour. © 2015 Periodical Offices of Chang'an University.
