Hollow Flange Steel Plate Girder (HFSPG) merupakan profil-I baja yang berbentuk persegi berlubang pada bagian sayap dan pelat badan. Proses pembentukan profil ini memerlukan proses cold-formed. Sambungan antara badan dengan menggunakan sambungan las berfungsi mengurangi terjadinya kegagalan sayap. Profil tersebut memiliki kekakuan torsi baik, sehingga dapat meningkatkan kapasitas lentur materia...

The hydrodynamic performance of the box-girder superstructure under extreme random wave conditions in actual ocean environment is focus coastal bridge designers and researchers. This paper proposed an analytical method to estimate forces on based potential flow theory correction parameters. accuracy validated by classical problem about force rectangular structure, empirical methods previous res...

With the development of economy and transportation, more cross-sea bridges are appearing in people’s view. However, not only subjected to repeated traffic loads but also corrosion from marine environment. In addition, steel box girder deck plate is directly vehicle loads, its welded details highly susceptible fatigue damage destruction, resulting or top plate-U rib girder. This paper based on f...

Accidental damage to prestressed concrete bridge girders may occur due impact by over-height vehicles on the bottom of girder, or top flange girder be damaged during deck removal and replacement operations. Since stress checks at service loads are an important component design for beams, serviceability-based should considered when assessing structural condition girders. In this paper, step-by-s...

This paper has evaluated the bending performance of a novel prefabricated MVFT steel-concrete composite girder. 9 meters pilot girder was analyzed by validated finite element model. In test, height web, length grouted concrete in and net spacing between webs were parametrically modeled to discuss their effect strength. An ultimate strength formula been obtained, which based on regression parame...

The steel-concrete composite girder bridge with V-shaped piers is a new type of structure. It has both the unique mechanical performance combined continuous and that pier bridge. At present, studies on properties steel main girders concrete deck slabs are mainly focused substructure for vertical piers, but not solidified. However, if cemented to girder, will directly affect total superstructure...

In order to study the relationship between an aerostatic three-component coefficient (ATCC) and bridge flutter quickly evaluate performance of bridges, we proposed a method based on empirical formula ATCC. The correlation driving term critical wind speed V nine bridges (six types girder sections) was analyzed, its rationality verified using tunnel test results. results showed that stability X-t...

Stressing adalah proses penarikan kabel tendon yang ada di dalam girder untuk menjadikan sebagai beton pretegang. satu arah yaitu sistem stressing strand dengan hanya menarik salah ujung saja. Sedangkan dua kedua kabel. Kehilangan gaya prategang yakni berkurangnya gaya-gaya bekerja pada suatu baja / (tendon) setiap tahap-tahapan pembebanan. Sehingga harus diperhitungkan berapa total kehilangan ...
