ABSTRAKBiaya merupakan salah satu hal penting dalam perencanaan konstruksi. Faktor utama yang mempengaruhi biaya adalah dimensi dan jenis material Penentuan beracuan pada persyaratan berlaku. Namun tersebut hanya memberikan rentang minimum maksimum. Maka perlu dilakukan perbandingan terhadap tersebut. Dalam kasus ini perhitungan struktur girder jembatan. Dilakukan 4 variasi steel box girder. Da...

This paper proposes an autonomous inspection method for steel box girders that uses a wall-climbing robot instead of human workers. According to the 3D operating environment inside girder, path traverse positions be inspected. The comprises two alternate sections lane’s centerline and U-shaped steering. To realize robot’s tracking desired path, kinematics analysis based on different poses durin...

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 ...

A very detailed 2D-solid finite element model is developed representing the load carrying box girder of a wind turbine blade. Using typical geometrical values for the girder dimensions and public available material data, the overall cross-sectional behaviour is analysed for a simple compressive line load. The results are compared with result from similar shell models, which typically are used f...
