The definition of sustainability includes three fundamental pillars: economic, environmental, and social. Studies the economic impact on civil engineering infrastructures have been focused cost reduction. It is not necessarily in line with due to lack other factors. Moreover, social pillar assessment has weakly developed compared environmental ones. essential focus evaluate clear indicators tha...

of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...

Several of the texts on prestressed concrete illustrate the magnitude of the effect of prestressing on the concrete by using a fishing pole as an example. As I recall the fishing pole described, it consists of a length of concrete one inch square in section with a single wire pretensioned through and along its central axis. Not until I was to witness the behavior of the massive precast, postten...

Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...

Steel girder bridges with member decks belong to the most frequently used types of superstructures old riveted steel railway bridges. During their service life, bridge deck members are affected by escalating effects traffic loads that significantly exceed those for which they were originally designed. As a result, these structures often subject increased fatigue degradation. One typical cases d...

This research is to assess the influences of inertial mass from girder on dynamic characteristic, response, and structure-soil interaction a pile-soil-pier subsystem in scale-model cable-stayed bridge. Therefore, both connection configurations between girder, including sliding fixed connections, were designed present various superstructure delivered pile-soil-pier. The supported by 3 × pile-gro...

This paper is focused on the suitability of selection parameters supporting structure bridge crane for needs cross-section optimization. The cross section beam analysed in terms its rigidity and dimensions with respect to span crane. When optimizing reduce overall weight, recommendations are given address issue cross-sectional stability. An iterative procedure design at specified load capacity ...
