A viscoplastic foam model for prediction of asphalt pavement compaction
Compaction is one of the most important factors affecting the future performance of asphalt pavement. Hot mixture asphalt materials exhibit significant time-dependent response under mechanical and thermal loadings, which can involve elastic, creep and plastic permanent deformation. The irreversible permanent deformation part will generate compaction. Foam-type model has been considered an effic…
Finite Element Modeling of Dynamic Tire/Pavement Interaction
Tire/pavement interaction has been an important research topic in pavement engineering for many years. This paper presents a finite element model for dynamic tire/pavement interaction, which can effectively include the dynamic tire rolling effect to predict the pavement response. The model represents a 4?tire vehicle. The tire is modeled as a finite strain hyperelastic material and pavement str…
Data Analysis of Sield Tunnel Deformation from Real-Time Monitoring with Wire…
As an important part of critical infrastructure, shield tunnel is widely used in urban area of China recent years. The safety of shield tunnel during construction and operation has drawn more and more attention. In the operational period, real time deformation monitoring is an effective way to help us to reveal the long-term deformation mechanism and control the lifetime safety of shield tunn…
Analysis of Soil Disturbance Caused by DOT Excavation in Soft Soil Stratum
DOT has the characteristics of special section and relatively large area of excavation face. Its propulsion will cause large formation disturbance. But too much soil disturbance usually leads to a series of environmental diseases. 3D elastoplastic FDM model was applied to analysis the dynamic construction process relying on a DOT project in Shanghai. Surface displacement field and the distrib…
Physical Layer Network Coding For Bridge Wireless Monitoring
Structural Health Monitoring of bridges has aroused the interest of many researchers on various disciplines. Our purpose in this paper is to make an overview on SHM of bridges from two different research areas: Civil and Communication Engineering. For the former part, we provide some insights into the objectives and the ways SHM of bridges is made. For the Communication Engineering side, we …

FRP-Strengthened Metallic Structures
epairing or strengthening failing metallic structures traditionally involves using bulky and heavy external steel plates that often pose their own problems. The plates are generally prone to corrosion and overall fatigue. Fiber-reinforced polymer (FRP), a composite material made of a polymer matrix reinforced with fibers, offers a great alternative for strengthening metallic structures, especia…
