Bridges in the United States require element-level inspections every 24 months, typically relying on laborious manual assessments. Three-dimensional (3D) point clouds from LiDAR or photogrammetry can facilitate these inspections, but are difficult to leverage without automatically identifying individual structural elements. Existing research focuse...
The National Bridge Inspection Standards require detailed element-level bridge inspections. Traditionally, inspectors manually assign condition ratings by rating structural components based on damage, but this process is labor-intensive and time-consuming. Automating the element-level bridge inspection process can facilitate more comprehensive cond...
An updated probabilistic seismic hazard assessment (PSHA) of Pakistan is performed using the procedures developed for the US national seismic hazard maps and Earthquake model of the Middle East (EMME14). An updated earthquake catalogue is compiled using data from multiple databases. The background seismicity of the study area is modeled using the a...
In the general practice of performance-based seismic assessment and dynamic analysis of building structures, the recorded ground motions from past earthquake events are selected and modified according to the site conditions and hazard level of the project’s site. For this purpose, only the mainshock earthquake event is considered for the analysis w...
p>Manual bridge inspections are often inefficient, costly, and dangerous. To address these challenges, researchers have been exploring the use of digital twins—digital replicas of physical bridges containing structural and condition data. This paper proposes a novel methodology for the automated production of geometric digital twins of reinforced c...

In this study, an updated probabilistic seismic hazard assessment (PSHA) of Pakistan region is performed using the procedures developed for the US National Seismic Hazard Maps and the Earthquake Model of the Middle East (EMME14). It is based on the combination of conventional area sources model and the spatially smoothed gridded seismicity model wi...
In this study, an updated earthquake catalogue and seismic source model for Pakistan region (bounded by latitude 20°–40° N and longitude 58°–83° E) are developed. The updated catalogue consists of published historical (10 to 1900 CE) and instrumental earthquake events (1900 to 2018 CE) with moment magnitude (Mw) ≥ 4.0. For this purpose, several int...
Earthquakes around the globe are threatening both human lives and infrastructure. It is essential to assess risk perception of people to introduce appropriate disaster risk reduction strategies. This study aims to identify various factors influencing people’s perceptions of earthquake risk. The survey was conducted in earthquake-prone sub-districts...
