“…This type of collapse due to a localised structural failure has resulted in a significant number of deaths, injuries, and economic losses. Historical and recent examples include bridges over the Birz river (Switzerland, 1891), the Quebec bridge (Canada, 1907), the I-35 bridge (USA, 2007), or the Chauras bridge (India, 2012) [1][2][3][4]. Studies carried out in the United States in an eleven-year period (1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000) have shown that the dominant types of failed bridges are steel beam/girder and steel truss bridges, accounting for more than 50% of the collected bridge failures in the US [5].…”

Metal and steel truss bridges are essential for transportation networks worldwide but are vulnerable to collapse due to deterioration and increasing traffic loads, particularly for ageing structures. Several bridge collapses, such as the Seongsu bridge (South Korea, 1994), I‐35 bridge (USA, 2007), and Chauras bridge (India, 2012), have highlighted the need to develop accurate robustness assessment strategies and efficient mitigation of collapse risks. This paper summarizes results of experimental and computational studies for a steel riveted bridge with a truss‐type structure. The experimental component presented involves unique tests to be performed on a 21 m full‐scale bridge span subjected to the failure of different elements under laboratory conditions. The paper then presents a first approach to explore different damage and failure scenarios for steel truss bridges, which will assist in defining data collection strategies for optimised monitoring and developing data analysis methods for real‐time diagnosis of ageing bridges. With this, the paper contributes to avoiding progressive collapses and presents a framework, developed as part of an ongoing project, to identify vulnerable zones for prioritising monitoring systems that anticipate failure propagation and prevent collapse. The framework is based on a systematic analysis of past bridge failures and simulations of carefully designed generic cases.

“…The failure of a bridge can be catastrophic as it can cause injury or death as well as being be very expensive to restore [7]. In the Chauras bridge uplifting of the side span during deck slab casting caused its failure [8]. Continuous span steel truss bridges can be constructed with the advantage of approximately 1/3rd mid span sagging moment, and 2/3rd support hogging moment, of the total simply supported span moment.…”

“…Continuous span steel truss bridges can be constructed with the advantage of approximately 1/3rd mid span sagging moment, and 2/3rd support hogging moment, of the total simply supported span moment. This type of construction was adopted in case of Chauras and Garudchatti bridges [8], [9]. Three span continuous truss geometry was adopted in these cases, where side to main ratio was kept as 0.364.…”

“…Composite construction of RCC floors with trusses is common in case of building construction, and with steel plate girders in case of composite plate girder bridges. There is no direct literature available for capacity calculation of the composite steel truss bridges in plastic stage [8]. Despite unavailability of proper design guidelines and design standards for composite truss bridges, various types of composite truss bridges have been constructed in the World.…”

In trusses, deck type and through type truss systems are generally provided with various member arrangements. To utilize the materials used in the trusses more efficiently, RCC decks are nowadays made composite with the truss members. In this paper, analysis of 72.0 m deck type and through type, non-composite and composite bridges is presented. The bridges are modelled using STAAD. Pro v8i software with truss members as beam element and deck slab modelled as four noded plate element. The loading on the bridge is done as per the provisions of IRC-6 and IRC-24. The composite deck effectively reduces the horizontal deflections due to lateral seismic and wind loads in both the truss systems. Decrement in vertical deflection of the truss system was also observed making the structure mode stiffer. Stresses in the members made composite with the deck slab were also reduced and hence resulted in material saving and decreased steel offtake. In the case of composite deck type bridges due to load sharing by the deck slab, the stresses in the top chord are reduced significantly hence eliminating the chances of buckling. Advantages of composite deck are better utilized in deck type bridge system compared to through type bridge system.

“…Top chord compression members of a simply supported steel truss bridge may prematurely and suddenly buckle before the material reaches its full compressive strength. In 2012, an open web steel girder non-composite deck bridge of 190m total continuous span (40m+110m+40m) suddenly collapsed (figure 1) during casting of the deck slab due to buckling of its top chord member U13U14 [1].…”

: In the literature, provisions for analysis and design of steel-RCC composite deck type truss and cable-stayed bridges do not exist. A composite deck type truss bridge model is analyzed using STAAD Pro V8i software and a model with the same dimensions is tested in the laboratory. The experimental test results are used to validate the STAAD analysis results. Bottom chord strain and mid-span deflection of the composite bridge model as found from the STAAD analysis and the laboratory experiment closely tally with each other. This validates the standard STAAD analysis results. However, in the top chord member, due to shrinkage cracks in the deck slab concrete, the experimentally recorded strain is higher by about 100% than the STAAD analysis result. Shear force in studs is considerably large near supports and joints as compared to the midsection. Therefore, the design of shear studs may be carried out based on the shear forces in the studs found from the STAAD analysis. Thus it is recommended that STAAD or any other standard finite element analysis software can be used for analysis and design of the composite bridges.
