The mechanical behavior of the adhesive interface between the fiber-reinforced polymer (FRP) strip and the concrete substrate often controls the response of FRP-strengthened reinforced concrete (RC) members. Plenty of studies devoted to understanding the mechanical behavior of FRP strips glued to concrete are currently available in the scientific literature. However, they are mainly focused on ...

This paper considers the cooperative control of a group of autonomous underactuated vessels (AUV). The control objective for each vessel is to maintain its position in the formation while Formation Reference Point (FRP) tracks a predefined spatial path. In order to achieve this goal, we use vectorial backstepping to solve two subproblems: one is geometric task, anther is dynamic task. The forme...

We present our experiences integrating Functional Reactive Programming (FRP) into a new host language, Python, and a variety of computational contexts: a game engine, a GUI system, and an embedded controller. We demonstrate FRP principles extended to a dynamic environment and the integration of object-oriented libraries into the reactive environment. A number of FRP semantic issues are addresse...

A large database consisting of 832 axial compression tests results of fiber reinforced polymer (FRP)confined concrete specimens was assembled. Using the test database, existing conventional and evolutionary algorithm models developed for FRP-confined concrete were then assessed. New genetic programming (GP) models for predicting the ultimate condition of FRP-confined concrete were developed. Th...

A Model to Predict the Long-Term Strength of E-Glass Fiber Composites Subjected to Environmental Exposure Thomas Miles Damiani Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degr...

fi ber reinforced plastic (FRP) re. nforcement is one of the most promising new developments for concrete structures. FRP reinforcing elements provide lighter, easier to assemble, and more durable structures that are free of the deterioration caused by corrosion of steel. FRPs consist of synthetic or organic highstrength fibers, most of which are impregnated with a resin matrix. They are availa...

This paper identifies assessment techniques for critical parameters relative to installation and performance of fiber reinforced polymer (FRP) materials as a way to strengthen structurally deficient concrete bridges. Various Nondestructive Testing (NDT) techniques, representing viable solutions for identification and monitoring of such critical parameters on structural members strengthened with...

Basalt continuous fibers are regarded as an inert and naturally occurring material that is produced from basalt rock by using single component raw material and drawing and winding fibers from the melt. Basalt based materials are environmentally friendly and nonhazardous. Basalt FRP (BFRP) composites as a reinforcement not only display a higher strength and modulus, but also a similar cost, and ...

Jacketing technology using fiber reinforced polymer (FRP) composites is being applied for seismic retrofit of reinforced concrete (RC) columns designed and constructed under older specifications. In this study, the authors develop an electromagnetic (EM) imaging technology for detecting voids and debonding between the jacket and the column, which may significantly weaken the structural performa...

Study the tensile damage and fracture behavior of FRP composite materials by the acoustic emission technology, broadband sensors record the acoustic emission signals when composite materials in the process of tensile damage at different fiber angle. The acoustic emission characteristics of FRP composite materials’ tensile damage was analyzed by 3D parameter methods. Analysis the amplitude of co...
