Abstract: Many studies have been conducted to investigate the seismic fragility of regular girder bridges, whereas only a few studies have focused on irregular cable-stayed bridges. In this study, the performance of a medium-span ...

Abstract: As an important part of the energy transportation system, oil and gas pipelines are developing toward intelligence and digitalization. Vigorously developing and constructing pipeline networks based on intelligent methods ...

Abstract: Traditional sacrificial concrete retaining blocks (CRBs) play a significant role in reducing the excessive transverse displacements of bridge superstructures and protecting the substructures from severe damage during seismic ...

Abstract: The huge axial force in the main girder challenges the design of superspan cable-stayed bridges. To reduce the self-weight of the girder, the conventional orthotropic steel deck (OSD) system is widely adopted due to its ...

Abstract: This paper develops a simplified method using a summation procedure and a related computer program to calculate the time-dependent behavior of a concrete filled steel tubular (CFST) arch bridge based on the geometric ...

Abstract: A novel lightweight prestressed ultrahigh-performance concrete (UHPC) bent cap is proposed, consisting of a large cantilevered thin-walled box girder weighing approximately 40% less than normal concrete bent caps. The ...

Abstract: This paper presents issues in the design concept, analysis, and test results of a harp-shaped single span cable-stayed bridge, Hongshan Bridge, located in Changsha, Hunan Province, China. The bridge has a 206 m span, with ...

Abstract: This paper describes results from a study evaluating stringless paving using a combination of global positioning and laser technologies. A concrete paver manufacturer and a machine guidance solution provider developed this ...
