The girder of self-anchored suspension bridge is subjected to large compression force applied by main cables. So, serious damage of the girder due to breakage of hangers may cause the collapse of the whole bridge. With the time increasing, the hangers may break suddenly for their resistance capacities decrease due to corrosion. Using nonlinear static and dynamic analysis methods and adopting 3D...

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...

A concrete bridge over Interstate 70 east of Denver, Colorado was impacted by a fork lift being transported by a truck moving at a speed of approximately 75 mph. The forklift impacted the east face of the prestressed concrete I-beam bridge girder, resulting in severe cracking and concrete spalling on both sides of the eastmost girder. Polymer-modified repair mortar was used to repair spalled ar...

Continuous rigid frame bridge is a common type of bridge in California, where is a seismically active areas. Main structural features of the bridge, including asymmetry, hinge structure, concretion of girder and piers affect the seismic response of the bridge significantly. In order to evaluate the safety of the bridge under earthquake, the nonlinear models of girder, limiting steels in hinge, ...
