So the change in boundary condition will make the deflection of the diaphragm different. For a precision device, any effect of a change in boundary condition can affect the deflection of the diaphragm largely. Thus, any effect of imperfect welding in a high precision measuring device can hamper...
The maximum vertical deflection of the bridge deck was observed on the west side of the steel girder at the mid-span of the CSB (position S1), reaching a magnitude of 1388 mm. The deflection measurements were taken at various points, including the mid-span of the main girder, the 300 m...
range of 9 to 12. When using a composite deck with a PBL open-hole steel plate, the maximum longitudinal slip at the plate end and within the span is only 0.28 mm and 0.0158 mm, respectively. These values are 31% and 36% lower than those of the composite deck with a peg shear key...
The structural parameters included the deck width, the flange thickness, the web height, and the web horizontal inclination. By extracting the load-mid-span deflection relationship curves of the deck under different structural parameters in the finite element program, the influence of different ...
During the initial calculation, the vertical constraint of the contact between the middle and rear wheels and the bridge deck is released, and it is assumed that the middle and rear wheels move freely. When they contact the bridge deck, the vertical displacement of the contact point is ...
