Applying master curve at the grids strengthened asphalt structures

Development of Asphalt Dynamic Modulus Master Curve Using Falling Weight Deflectometer Measurements, TR-659

The asphalt concrete (AC) dynamic modulus (|E*|) is a key design parameter in mechanistic-based pavement design methodologies such as the American Association of State Highway and Transportation Officials (AASHTO) MEPDG/Pavement-ME Design. The objective of this feasibility study was to develop frameworks for predicting the AC |E*| master curve from falling weight deflectometer (FWD) deflection-...

Modeling of FRP-Strengthened Infill Masonry Structures

This paper presents an analytical approach to describe the behavior and mode of failure of infill masonry structures strengthened with fiber-reinforced polymer (FRP) materials. The approach is used to simulate the response of strengthened infill masonry walls under the effect of out-of-plane uniformly distributed pressure simulating wind pressure. The approach includes a finite element analysis...

Bond Behavior of Cfrp Strengthened Steel Structures

Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...

Evaluating the Fire Performance of FRP-strengthened Concrete Structures

Building and applying geographical information system Grids

We discuss the development and application of Web Service-based Geographical Information System Grids. Following the WS-I+ approach of building Grids on Web Service standards, we have developed Data Grid components for archival and real-time data, map generating services that can be used to build user interfaces, information services for storing both stateless and stateful metadata, and service...
