<p>A bridge’s bearings, arguably its most critical components, perform a vital function throughout the bridge’s service life, but the bearings used can also have a significant impact on the bridge construction process. Suitably designed adjustable bearings are an integral part of the incremental launch method of bridge construction, for instance, which can be a very efficient construction method. Adjustable bearings may also support other bridge construction methods, such as segmental bridge construction, where fixities/freedoms that applied during the construction phase require to be changed before the bridge enters service. Lifting bearings, the height of which can be increased, may enable a lack of precision in the structure to be tolerated, and measuring bearings may enable load distribution during bridge construction to be verified, where this is required by the construction method. Design features of otherwise standard bearings that support quick and high-quality installation can also contribute towards the efficiency of the overall bridge construction process, as can the use of bearing designs which minimize bearing size. Bearing solutions and features that facilitate bearing installation and bridge construction in ways such as these are described.</p>

Greenhouse effect and greenhouse gas mitigation practices are becoming global issues in recent years. The government in Taiwan has also developed policy to reduce CO2 emission and save energy in construction of public projects. The objective of this research is to identify the influencing factors on the CO2 emission of bridge construction projects in Taiwan. Examples of those factors are the type of superstructure, the type of lower structure, the construction methods, the location of the project, and so on. The rules of Carbon footprint are used to calculate the CO2 emission of around 31 bridge construction projects in Taiwan. Results of the calculation of these case projects are then compared to each other for analysis to identify the influencing factors on the CO2 emission of bridge projects in Taiwan. Public owners and designers can refer to those identified factors for constructing bridges with lower CO2 emission. The goal of reducing CO2 emission in construction can be facilitated.

Accelerated Bridge Construction (ABC) is bridge construction that uses innovative planning, design and construction methods in a safe and cost-effective manner, which reduces construction mobility and environmental impacts, and contributes to city sustainable planning and development. To deal with the pressing need to support the decisions associated with the selection between the ABC and conventional bridge construction, this paper presents the development of a multi-criteria evaluation framework. Methods are developed and identified to estimate the construction, agency, and user costs associated with the construction methods. A novel model was developed to allow the estimation of the construction and agency costs of ABC relative to conventional construction. This paper also demonstrates the estimation of user costs, including those associated with mobility, reliability, safety, and emissions, utilizing combinations of the proposed prediction method. The paper then compares the use of the return-on-investment and Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) Multi-Criteria Decision Making (MCDM) evaluation approaches in the decision to select between ABC and conventional bridge construction. The results from the employment of the two approaches to a case study demonstrate the advantage of using the TOPSIS approach, which is also applicable in the urban planning process.

Acceleration of bridge construction requires the development of new construction methods. In composite steel concrete bridges the cast in situ bridge deck may be replaced by a precast deck. For fast assembly the joints have to be solved adequately. UHPC joints represent an alternative which can satisfy the requirements on mechanical properties of joints, on construction and economy. The function of the joints was experimentally verified using three different experiments. The performance of beams with precast and cast in situ slab was compared.

Cable Stayed Bridges

Sudan, being a wide country consisting of sixteen states, in which thousands of kilometers of waterways and valleys are extended, bridges had become desperately needed for proper communication and development. There were many types of bridges in Sudan made of concrete, steel, and composite sections showing various types of suspended, steel truss, arch, and cable-stayed bridges which were constructed by different methods.     This paper summarizes the data of main bridges in Sudan; it shows the construction duration, cost, and type of the superstructure and presents a comparison between bridges’ superstructure construction methods in terms of cost in US$ per m2 of the bridge plan area and production rate in m2/week. The paper also recommends the most favorable bridge construction methods that are expected to contribute better into saving cost and construction time.
