The automobile loading test was carried out at Geumdang bridge as shown
The automobile loading test was conducted at Geumdang Bridge as shown in Figure three. The bridge is in Yeoju, Gyeonggi-do, South Korea, and also the test sought to verify The bridge is in Yeoju, Gyeonggi-do, process of estimating the LLDF a a bridge working with traveling vehicles. bridge is spethe process of estimating the LLDF ofof bridge working with traveling cars. The The bridge is specifically positioned the Jungbunaeryuk Expressway and consists of 7-span PSC I cifically positioned on around the Jungbunaeryuk Expressway and consists of7-span PSC I girder and box girder bridges having a width of 12.6 m, a skew of 15 degrees, along with a total length of car loading conducted 273 m. The car loading test was conducted within the single-span 30 m section with two lanes composed of 4 PSC I girders as shown in Figure 3. The concrete of theof the girder lanes composed of 4 PSC I girders as shown in Figure three. The concrete PSC I PSC I had a had a strength of 70 MPa, when the slab had a strength of 35 girderstrength of 70 MPa, while the slab had a strength of 35 MPa. MPa.Test bridgeFigure 3. PSC I girder bridge.the car loading test, the displacement response was measured using linear Within the car loading test, the displacement response was measured making use of linear varvariable differential transformers (LVDTs) that had been installed 4 girders (G1 to to G4) iable differential transformers (LVDTs) that have been installed on on four girders (G1 G4) at at center of of L/2 point as as shown in Figure 4. Considering that the natural frequency of Gethethe center thethe L/2 pointshown in Figure four. Because the firstfirst all-natural frequency of Geumdang Bridge was 3.50 Hz, the data acquisition speed on the LVDTs was set at umdang Bridge was three.50 Hz, the 20(S)-Hydroxycholesterol Cancer information acquisition speed from the LVDTs was set at 100 Hz to collect more than 20 units of data in one particular period.
