"Once initial section sizing calculations had been performed, we then used LUSAS to analyse numerous post-tensioning layouts for a variety of construction stages... then, once a tendon layout that satisfied all stress limits had been found, strength checks were made and the tendon profile approved...
a bridge with span structures, the basic components of which are arches or vaults. Characteristic traits of an arch bridge are the transfer to the supports not only of the vertical but also the horizontal stresses (thrust), as well as the strain, primarily of compression, on the arches or ...
The longitudinal layouts of DLTW piers are similar to the transverse direction of double-column piers; thus, the commonly used transverse fuse bridge pier concept can be used in the longitudinal direction of the DLTW pier. This paper proposes an innovative double-limb-thin-wall (DLTW) bridge ...
Moreover, the sweeps excited the girders with three different target load amplitudes equal to 445 N, 2225 N, and 4450 N. Considering two layouts (see Figure 4) and three levels of load amplitudes, girders were tested under six frequency sweeps. A general view of the testbed structure during...
Besides, the classification accuracy of MLP drops to 93.58%, depending on the sensor layouts. However, MPNN is more stable with an accuracy of over 98.33% in all 5 cases. Also, for the cross-sectional area prediction, MPNN is better and more stable than MLP and XGBoost. Meanwhile, the ...
