A study focusing on optimization and efficiency of relatively common solution for small span railway bridges is presented. The superstructure of the bridges is created by reinforced concrete deck with encased steel beams. Especially, flexural behaviour was analysed in the study. Actual bridge cross-...
Figure 1. Flow chart of analysis. 2. Project Summary The main bridge of Mingzhu Bay is (96 + 164 + 436 + 164 + 96 + 60 m) a six-span continuous three-steel truss arch bridge with a total length of 1016 m. Double orthotropic steel decks are used. The upper deck is a two-way...
For the finite element simulation, the specific operation steps for obtaining the midspan deflection time-history curve are as follows: Step 1: Set the mass of the moving load, and keep driving on the bridge deck at low speed and at a uniform speed to obtain the midspan deflection time-hist...
Figure 2. Configurations of the Tianmeng Bridge: (a) Elevation (m); (b) Deck level plan (m); (c) Girder cross section (mm). In order to improve the structural stability of the girder, two wind-resistant cables are set up on both sides of the girder. The average horizontal inclinat...
Five rectangular diaphragm beams are connected to hold four girders at each span, having a girder depth of 1800 mm. The symmetry of the members are the same throughout the bridge; each pier shaft is 1200 mm in diameter. The cap beam has a dimension of 1800 mm × 1200 mm. Deck slab,...
