Research
Dr. Lin’s primary research goals are toward understanding of performance of structures and proposing advanced civil infrastructural materials through analytical, computation and experimental study to develop high-performance resilient and sustainable civil infrastructure systems. Three research areas mainly focus: Civil Infrastructural Materials, Performance, Diagnosis and Intelligent Structural Systems:
a) Civil infrastructural materials (Students: Mingli Li, Xingyu Wang, Naveed Metla, Yiming Bu)
b) Performance (Students: Mingli Li, Zi Zhang)
c) Diagnosis & Intelligent Structural Systems (Students: Zi Zhang, Matthew Pearson)

Selected Active Projects:
(Civil Infrastructural Materials) New Structural Coatings for Civil Infrastructure Corrosion Mitigation
Corrosion is one of the leading causes of failures of metallic civil infrastructure, such as bridges, pipelines and tunnels in the United States and worldwide. The locally severe corrosion of steel bridge H-piles near pile cap caused one portion of the Leo Frigo Bridge, Wisconsin, moving vertically 2 feet on Sep. 2013, ultimately leading to total cost of $20 million. Corrosion of onshore gas and liquid transmission pipelines were responsible for over $7 billion cost. Protective surface coatings are usually accepted for corrosion control to establish a physical barrier layer between the steel and environment. Coating deterioration, however, often initiates in the local areas adjacent to high exposures of wetness and other aggressive environments. Thus, it will be desirable to develop new structural coating for innovative solutions for civil infrastructure corrosion mitigation.

(Civil Infrastructural Materials) Phase Change Materials Based Composite for Energy Harvest Structures
 Civil infrastructure faces with big challenges under aggressive environments in cold regions. In this study, graphite integrated with phase change materials (PCMs) is selected for potential applications in energy harvest of heated civil infrastructure due to favorable thermal conductivity of the graphite, and isothermal nature and high thermal storage capacity of the PCMs.

(Performance) Design, and Service Life Prediction of New UHPC Based Steel-Concrete Composite Bridges with Corrugated Steel Webs
 New UHPC based steel-concrete composite bridges with corrugated steel webs are proposed to address the ever-increasing deteriorated bridge systems. This study aims to investigate the fundamental properties of the new composites with enhanced durability and develop the prediction modeling of the bridge systems.

(Diagnosis & Systems) Wireless Passive Sensor Networks with UAS for Critical Civil Infrastructure
 Critical civil infrastructure, such as wind turbines, railways, bridges and pipelines, is a key lifeline as networks for economy and society need. An innovative technology using the wireless passive networks with UAS is proposed through integrating data collection, data storage and processing, damage identification, and risk assessment for developing intelligent critical civil infrastructures. RF powered wireless sensor networks are distributed to predetermined locations, while the UAS will be utilized and through custom integrated circuit chip design to optimize on-board processing and storage for data in-situ transmission. With such, in-situ performance data will be available for timely assessing and managing these intelligent critical infrastructures.
