Comparison Of The Impact Of Probabilistic Versus Deterministic Ground Motions On Structural Responses Of A Steel Moment Building In Salt Lake City, Utah, O. Murphy, M. Zaker Esteghamati, B. R. Cox

Civil and Environmental Engineering Student Research

Earthquakes on the Wasatch Fault pose a significant hazard to Utah’s people and built environment. Code-based seismic design of civil infrastructure in Utah is governed by ground motions determined from regional probabilistic seismic hazard analysis (PSHA). However, with a large earthquake overdue along several segments of the Wasatch Fault, there is growing concern among Utah engineers that PSHA-based ground motions are significantly lower than those from a deterministic scenario. This study compares the structural responses of a four-story steel moment frame in Salt Lake City, Utah, under two ground-motion sets derived from risk-targeted probabilistic and deterministic seismic-hazard analyses. The preliminary …

Wildland Resources Student Research

Climate change is rapidly altering high-latitude coastal wetlands through increasing temperatures, more frequent flooding, and changing herbivore abundance and distribution. Examining plant functional trait responses to these drivers provides insight into how plant communities are shaped by climate change. We used a one-year full-factorial mesocosm experiment in coastal Alaska to assess immediate responses of two size-related traits (vegetative height and leaf area) and two leaf economics traits (specific leaf area [SLA] and leaf dry matter content [LDMC]) to warming, flooding, and goose herbivory in three dominant species across two wetland communities (Lowland and Upland) differing in landscape position. We sampled …

Civil and Environmental Engineering Student Research

This study examines the seismic response of reinforced concrete (RC) bridge piers subjected to ground motion (GM) records from the 2023 Kahramanmaraş earthquake by comparing the impact of pulse-like versus no-pulse records. A suite of 300 nonlinear Bouc-Wen hysteretic models was developed to represent piers with varying nonlinear behavior. Each Bouc-Wen model was assessed under 24 pulse-like and 28 no-pulse GMs, resulting in 15,600 nonlinear time-history simulations. Subsequently, the relationship between Bouc-Wen parameters (i.e., period and yield displacement) and seismic responses (i.e., maximum displacement, residual displacement, and maximum acceleration) was analyzed. The results show that pulse-like records produce 5 times …

When The Student Surpasses The Teacher: Better Generalization In Ai-Based Seismic Waveform Quality Assessment Using Knowledge Distillation, Ali Namin, F. Jalaeifar, A. Kottke, M. Zaker Esteghamati

Civil and Environmental Engineering Student Research

This paper presents a knowledge distillation (KD)-based approach to reduce computational expenses and improve the generalizability of deep learning-based models for quality assessment of seismic waveforms. Using two different waveform datasets, teacher models are distilled into lightweight student models from two families of time-series-based and image-based models. Models from both student families are trained on a development dataset and evaluated on the testing portion of the development dataset, as well as on an entirely different external testing dataset. Results indicate that KD can provide student models with substantially reduced size (5%-10% of the teacher model's size) and latency while preserving, …

A Context-Aware Computer Vision-Based Approach For Post-Earthquake Damage Assessment Of Bridge Inventories, Parham Bakhtiari, S. Ratna Pandey, M. Zaker Esteghamati

Civil and Environmental Engineering Student Research

Post-earthquake damage assessment is crucial to evaluate the safety and serviceability of bridges after an earthquake. Conventional screening methods rely on manual inspection, which is costly, time-consuming, and poses safety risks to inspectors. To address these challenges, this study presents a context-aware vision transformer framework for integrating structural element details into multi-defect identification through a late-fusion approach. The model is trained on a post-earthquake image dataset collected from three major earthquakes in Italy, consisting of 356 images. Five structural elements of reinforced concrete bridges are selected, where concrete spalling and reinforcement corrosion were chosen as target defects. The framework achieved …
