“…The higher materials costs of austenitic or duplex stainless steel have been shown to be compensated by reductions in maintenance over a 75-year service life. 66 Whereas stainless steels have more-than-adequate strength and corrosion resistance for infrastructure applications, 69 improvements in ductility are sought; investigations into twinning-induced plasticity can improve ductility while retaining strength, 70 but gains in stress-corrosion-cracking resistance and weldability are also desirable.…”

Concrete is the most used material on Earth except for water. Thus, there is much to be gained through improvements in the manufacturing of cement and the production of concrete to meet societal demand in a sustainable manner. This article reviews recent developments in three areas that have the potential to transform the ways in which infrastructure is specifi ed, designed, and constructed: (1) expanding the use of supplementary cementitious materials and the identifi cation of alternative supplementary cementitious materials, (2) growing the use of alternative cements and binder technologies, and (3) developing alternative reinforcement options. Strategies to facilitate the transfer of these emerging and next-generation materials and technologies from the research arena into real structures are also discussed.

“…Bearing maintenance and replacement is one of them. Different bearing types are available such as elastomeric bearings, cotton duck pads, sliding bearing, manufactured high load multi-rotational bearings and mechanical steel bearings among others (Azizinamini, Power, Myers, & Ozyildirim, 2014). However, INDOT generally only uses two types of devices: for concrete members elastomeric pad devices, and for steel structures elastomeric and steel bearings (INDOT, 2014).…”

“…The service life of elastomeric devices when they are well maintained, constructed and designed can last as long as the structure (Lee, 1994;Azizinamini et al, 2014). However, in order to achieve a service life of 100plus-years, more emphasis must be placed on manufacturing quality (Azizinamini et al, 2014). Aria and Akbari (2013) proposed a service life between 30 to 50 years, while Azizinamini et al (2014) based on surveys across the United States report a service life of between 50 to 75 years.…”

Life-Cycle Cost Analysis for Short- and Medium-Span Bridges

Life-cycle cost analysis (LCCA) has been defined as a method to assess the total cost of a project. It is a simple tool to use when a single project has different alternatives that fulfill the original requirements. Different alternatives could differ in initial investment, operational and maintenance costs among other long term costs. The cost involved in building a bridge depends upon many different factors. However, long-term cost need to be considered to estimate the overall cost of the project and determine its LCC. Without watchful consideration of the long-term costs and full life-cycle costing, current investment decisions that look attractive could be resulting in a waste of economic resources in the future. This research is focused on short and medium span bridges (between 30 ft and 130 ft) which represents 57% of the NBI INDIANA bridge inventory. Bridges are categorized in three different groups of span ranges. Different superstructure types are considered for both concrete and steel options. Types considered include: bulb tees, AASHTO prestressed beams, slab bridges, prestressed concrete box beams, steel beams, steel girders, folded plate girders and simply supported steel beams for dead load and continuous for live load (SDCL). A design plan composed of simply supported bridges and continuous spans arrangements was carried out. Analysis for short and medium span bridges in Indiana based on LCCA is presented for different span ranges and span configurations. Results will help designers to consider the most cost-effective bridge solution for new projects, resulting in cost savings for agencies involved.

“…That thinking is pursued in two directions. On bridges of up to several relatively shorter spans numerous publications, including (1) and (2) recommend jointless bridges and integral abutments. The large cyclic displacements of long-span bridges are accommodated by special expansion devices, such as the modular joints, designed and manufactured to detailed specifications including installation, maintenance and replacement.…”

Joints: the weak link in bridge structures and lifecycles

The condition of a bridge network over three decades is reviewed. The bridges comprising the network are considered as networks of structural elements. Deck joints are identified as the weak link in both networks. Typical modes of failure are shown for the joints most commonly used in New York City and the Metropolitan area. Bridge management options are examined in the context of deck joint performance.
