This work deals with the development of a mechanics-based shear model for reinforced concrete (RC) elements strengthened in shear with fiber-reinforced polymer (FRP) and a design/assessment procedure capable of predicting the failure sequence of resisting elements: the yielding of existing transverse steel ties and the debonding of FRP sheets/strips, while checking the corresponding compressive...

Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. This paper will summarize the results of a multi-phase experimental program undertaken at the University of Waterloo to investigate the viability of using externally bonded fiber reinforced polymer (FRP) laminates to rehabilitate corrosion-damaged reinforced concrete bea...

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premature cover delamination and FRP debonding are predominant failure modes in FRP flexural strengthening that may be delayed or prevented by using FRP ...

Functional reactive programming (FRP) is an emerging paradigm which allows the management of input/output and state within the confines of a purely functional language. The functional nature of FRP promises to make formal verification of functional reactive systems more tractable than that of their imperative counterparts. I propose to substantiate this claim by formally modeling FRP systems an...

One of the goals that the Innovative Bridge Research and Construction (IRBC) program, sponsored by the Federal Highway Administration (FHWA), wishes to achieve through sponsored research projects is the concept of an economical, durable, short-span bridge that reduces construction time. Delaware County, Iowa took a step in that direction through the construction of a 64 ft. long bridge comprise...

Fiber reinforced polymer (FRP) composites are getting a wide range of application areas in bridge rehabilitations because these materials are less affected by corrosive environmental conditions, known to provide longer life and require less maintenance. However, there are still some concerns about their long-term performance because currently limited data exists. Moreover, the quality control a...

As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...
