Abstract:Taking Liuyang River Bridge of Jia Liu Highway as an example, the design method and construction method of precast segmental concrete bridge are introduced, and the technical and economic benefits of this bridge type are analyzed.

Abstract:This paper takes the construction of Liuhe Bridge of Jia Liu Highway as an example, introduces the precast segmental concrete bridge construction method and should pay attention to some problems.

Abstract:Through the DP450 bridge erection machine in Liuhe bridge application example, introduced the characteristics of the machine and the use of the method.

Abstract:This paper introduces the prestressing construction process of track girders for Shanghai Maglev Railway. The pre-stressing construction of track girders is divided into pre-tensioning and post-tensioning methods, and the post-tensioning method adopts HVM anchorage, which is tensioned in two times, in order to minimize the effect of concrete shrinkage and creep on the track girders. At the same time, the problem of placing the limit plate which should be paid attention to in the construction of this project is introduced.

Abstract:This paper summarizes the pre-stressing construction process of Tanzhong viaduct, focusing on the construction process and the application of new pre-stressing tensioning equipment in the construction.

Abstract:This paper mainly introduces the prestressing vertical reinforcement, the use of HVM large-hole anchorage and tensioning, and at the same time gives a brief introduction to the construction of large-span rigid box girder prestressing.

Abstract:This paper briefly introduces the application of MSC/PATRAN and MSC/AFEA in the analysis of prestressed concrete structures by analyzing the stresses under the prestressed concrete anchors.

Abstract:In this paper, MSC.PATRAN and MSC.AFEA software are applied to calculate the intrinsic frequency of a single-arch simply-supported bridge and to analyze the response of the bridge under simulated dynamic loads.

Abstract:In this paper, MSC.PATRAN and MSC.AFEA software are applied to calculate the intrinsic frequency of a single-arch simply-supported bridge and to analyze the response of the bridge under simulated dynamic loads.

Abstract:The purpose of this paper is to describe the static interception, dynamic loading and long-lasting tests of bridges, to provide the author's experience for discussion and to publicize the latest research results in this field.

Abstract:This paper describes a British method of actively controlling bridge loads, whereby the bridge structure is systematically controlled so that the chances of reaching critical loads are very small.
