The limitations are particularly problematic for activities related to...

Digital twin construction (DTC), the virtual replica of physical construction, is an essential enabler for the promised Construction 4.0. Thanks to its real-time virtual-physical synchronicity, many uncertainty-tolerant functions, and applications, such as system integration, testing, monitoring, and maintenance, could be dynamically simulated and...

This paper explores the application of automated machine learning (AutoML) techniques to the construction industry, a sector vital to the global economy. Traditional ML model construction methods were complex, time-consuming, reliant on data science expertise, and expensive. AutoML shows the potential to automate many tasks in ML construction and t...

Mobile cranes are essential equipment in constructionsites due to their high flexibility and mobility. However,the existing sensing or monitoring methods havelimitations in monitoring mobile cranes on sites.Recently, the advent of 4D point cloud (4DPC)technology with a unique spatial-temporal data structurehas shown potential in addressing these is...

[Free PDF:🌐 https://frankxue.com/#publications 🌐] Machine learning (ML) has been recognized by researchers in the architecture, engineering, and construction (AEC) industry but undermined in practice by (i) complex processes relying on data expertise and (ii) untrustworthy 'black box' models. As a result, ML results of complex non-linear AEC proble...

A resilient bridge system with smart bearings, that is, shape memory alloy (SMA)-cable-based bearings, is proposed. Its superior resilience property over the conventional bridge system still lacks a practical assessment approach. This paper aims to conduct a comparative performance assessment of both resilient and conventional bridge systems regard...

This study discussed a novel self-centering rocking (SCR) bridge system equipped with shape memory alloy (SMA)-based piers, with a particular focus on the benefit of the SCR bridge system in a life-cycle context. The study commences with an introduction of the SCR bridge system; subsequently, a life-cycle loss and resilience assessment framework fo...

This study presents a novel type of shape memory alloy (SMA) cable-restrained high damping rubber (SMA-HDR) bearing, which is particularly suited to near-fault (NF) regions where the pulsing effect potentially exists in the ground motions. The working mechanism of the bearing is first described, followed by an experimental investigation on a full-s...

Seismic isolation bearings have been extensively used for seismic damage mitigation of bridge structures. Conventional pure friction (PF) sliding bearing is often criticized by some problems such as excessive sliding displacement and unrecovered deformation under strong ground motions. To solve these problems, this paper proposes a new SMA-cable-ba...

This study proposes a new footing rocking pier which employs shape memory alloy (SMA) washers as its kernel elements. Apart from providing self-centering capability and energy dissipation, the SMA washers enable a ‘‘limited rocking’’ behavior for the pier, helping enhance the seismic resilience of the bridges. The study commences with quasi-static...

The emergence of rocking bridge piers provides the community of civil engineers with a broader vision of next-generation seismic-resilient bridge design. This study introduces a new type of shape memory alloy (SMA) washer spring-based self-centering rocking (SCR) systems which could be an important addition to the existing rocking pier family. The...
