Identification Of Scaffold Defect Risk Factors And Risk-Tier Inspection Intervals For Vietnam Construction Sites, Hong Ha Le, Duc A. Nguyen Jun 2026

Identification Of Scaffold Defect Risk Factors And Risk-Tier Inspection Intervals For Vietnam Construction Sites, Hong Ha Le, Duc A. Nguyen

CIB Conferences

Scaffold failures are a persistent safety burden driven by assembly quality variability, environmental exposure, and frequent site modifications. This study develops and validates a risk-tier inspection scheduling framework that converts routine scaffold inspection logs into interval-level predictions of critical defects. Using 950 inspection intervals from three Vietnamese regions (Northern, Middle coastal, Southern), a complementary log-log model with Elastic Net regularization predicts whether a critical defect will be detected at the next inspection. Critical events occurred in 14.21% of intervals. The model achieves strong discrimination (ROC-AUC = 0.995, AP = 0.984, Brier = 0.018); at the operating threshold, Precision = 1.000 …

A Multi-Fidelity Approach For Forecasting Seismic Responses In Building Structures, Quynh Doan Thi Mai, Viet Hung Dang, Trong Phu Nguyen Jun 2026

A Multi-Fidelity Approach For Forecasting Seismic Responses In Building Structures, Quynh Doan Thi Mai, Viet Hung Dang, Trong Phu Nguyen

CIB Conferences

In this study, a hybrid physics-based and data-driven model is proposed to reliably forecast the dynamic responses of structures under time-varying excitations. While detailed physics-based models are accurate, they are computationally intensive; conversely, purely data-driven models are efficient but highly dependent on data quality and volume. The proposed hybrid approach bridges this gap by combining a fast, low-fidelity physics-based model with a data-driven corrector to predict the residuals between the low-fidelity approximation and the high-fidelity target. Specifically, the low-fidelity physical model relies on a multi-degree-of-freedom mass-spring-damper system, while the data-driven corrector is based on a selective state-space neural network. The …
