Typically, the dynamic resistance is proxied by a seismic yield coefficient, and the seismic loading is proxied in part by the spectral acceleration at the degraded fundamental period of the slide mass. However, inherent soil spatial variability within slope systems can significantly contribute to uncertainties in these variables, which can propagate to uncertainties in the evaluated seismic displacements. This study investigates the influence of subsurface soil variability on the resulting uncertainty in the seismic yield coefficient, slide mass period, and estimated displacements for a series of hypothetical clay slopes. Pseudostatic stability analyses were performed using the finite difference program FLAC for approximating the seismic yield coefficient, the associated slide mass geometry, and slide mass period. Seismic displacements were determined using a state-of-practice simplified procedure for 40 ground motions. The soil was modeled using lognormal spatial random fields of the undrained shear strength, with alternative assumptions for the mean, coefficient of variation, and horizontal correlation range. Other parametric variations included alternative assumptions for the shear wave velocity, soil shear strength characterization, and slope geometry. The results demonstrate important considerations for interpreting the combined uncertainty (i.e., inherent soil variability and associated biases, compounded with modeling uncertainty) for practical evaluations of seismic displacements.

The performance objectives of the prefabricated segmental tunnels were divided into five levels: basic intact, operational, repairable, medium-repairable, and severely damaged. To obtain quantifiable performance indicators for prefabricated segmental tunnels that correspond to these performance objectives, this study investigated two adjacent ring segments of 19 sealed roof blocks at different positions based on four classic sites. Finite element models with refined details were utilized for the pushover analysis to obtain the capacity curves for the segment structures. Based on the relationship between the capacity curves and the performance objectives, the limit values of the diameter change rates for each case were determined using geometric plotting methods. The limit values of the diameter change rates for the prefabricated segmental tunnels corresponding to the five performance levels were determined to be 1/1850, 1/320, 1/180, 1/160, and 1/130.

However, the understanding of seismic wave propagation and ground motion attenuations, particularly considering source-path-site effects, remains limited, becoming a key bottleneck in the seismic design of WTs. To address this, this paper assesses the seismic performance of WTs by analyzing the combined effects of seismic source characteristics, wave propagation paths, and local site conditions, and proposes a novel method for assess site effects on WTs in mountainous regions using scenario-based earthquake simulations. In the methodology, the frequency-wavenumber (FK) method is employed for the semi-analytical solution of deep crustal Green's functions, the spectral element (SE) method for efficient large-scale wave field simulations, and the finite element (FE) method for detailed structural modeling of WT responses. The resulting FK-SE-FE approach enables a full-process physics-based simulation from fault rupture to the structural response.

Results indicate that the presence of the mountain during seismic wave propagation significantly increased the overall seismic response of the structure, with the tower-top displacement of the mountain-top WT being amplified by up to 2.56 times compared to the mountain base.
