Fiber-reinforced polymer (FRP) has been a practical alternative construction material for replacing steel in the construction industry for several decades. However, some mechanical weaknesses of FRP are still unresolved, which limit the extensive use of this material in civil infrastructure. In order to mitigate the disadvantage of using FRP, the concept of hybridization is delivered here. The advantages of hybrid structural systems include the cost effectiveness and the ability to optimize the cross section based on material properties of each constituent material. In this chapter, two major applications of hybrid FRP composites are discussed: (1) the internal reinforcement in reinforced concrete (RC) structures, and (2) the cables in long-span cable-stayed bridges. In order to improve the flexural ductility of FRP-reinforced concrete (FRPRC) beam, the additional steel longitudinal reinforcement is proposed such that the hybrid FRPRC beams contain both FRP and steel reinforcement. In order to improve the vibrational problem in pure FRP cables used in bridge construction, an innovative hybrid FRP cable which can inherently incorporate a smart damper is proposed. The objective of this chapter is to deliver an up-to-date review of hybrid FRP composite structures, including both the industrial practice and the research in academia. The advantages of using hybrid FRP composites for construction will also be described with experimental support. It is hoped that the reader will appreciate the concept of hybridization, which leads to the efficient utilization of all constituent materials in a bonded system.

This chapter summarizes the recent advances in the use of fiber-reinforced polymer (FRP) materials for repair, rehabilitation, and strengthening of steel structures. Conventional methods of strengthening and repairing steel structures are presented. The advantages and limitations of using FRP materials are summarized. Topics presented include strengthening of flexural members, strengthening with prestressed FRP materials, stress-based and fracture mechanics-based approaches to evaluating bond behavior, repair of cracked steel members, and strengthening of slender members subjected to compression forces. The chapter concludes with a brief discussion of future trends in this field and a summary of other resources for further information.

This chapter presents a systematic approach for material characterization, analysis, and design of all-fiber-reinforced polymer or plastic (FRP) composite structures. The suggested ‘bottom-up’ analysis concept is applied throughout the procedure, from materials/microstructures, to macro components, to structural members, and finally to structural systems, thus providing a systematic analysis methodology for all-FRP composite structures. The systematic approach described in this chapter can be used efficiently to analyze and design FRP shapes and bridge systems and also develop new design concepts for all composite structures.

Fiber-reinforced polymer (FRP) composite materials have been increasingly used in civil engineering applications in the past two decades. Their wide ranging use, however, is still not realized due to a few fundamental issues including high material costs, relatively short history of applications and the gaps in the development of established standards. Design safety requires that all possible modes and mechanisms of failure are identified, characterized, and accounted for in the design procedures. This chapter provides a review of the failure types encountered in structural engineering applications of FRP and the preventive methods and strategies that have been developed to eliminate or delay such failures. As part of preventive measures, various non-destructive testing (NDT) and structural health monitoring (SHM) methods used for monitoring FRP applications are discussed with illustrative examples.

The chapter begins by discussing a new type of sandwich panel called composite structural insulated panels (CSIPs) intended to replace the traditional SIPs that are made of wood-based materials. A detailed analytical modeling procedure is presented in order to determine the global buckling, interfacial tensile stress at facesheet/core debonding, critical wrinkling stress at facesheet/core debonding, equivalent stiffness, and deflection for CSIPs. The proposed models were validated using experimental results that have been conducted on full-scale CSIP walls and floor panels. In order to be used as a hazard-resistant material, a detailed section was presented to show the resistance of CSIP elements to the different types of hazard effects, including impact loading, floodwater effect, fire effect, and windstorm loading.

Modular panelized construction is a modern form of construction technique in which precast multifunctional structural panels are used. In this technique, precast panels are fabricated in the manufacturing facility and are transported to the construction site. Traditional structural insulated panels (SIPs) consist of oriented strand boards (OSB) as facesheets and expanded polystyrene (EPS) foam as the core. These panels are highly energy efficient but have issues in terms of poor impact resistance and higher life cycle costs. Proposed panels consist of E-glass/polypropylene (PP) laminates as facesheets and EPS foam as core and are called composite structural insulated panels (CSIPs). Proposed CSIPs overcome the issues of traditional SIPs and retain all the energy-saving benefits of the traditional SIPs. This chapter describes manufacturing techniques developed for CSIPs and connection details for bonding CSIPs on the construction site. Based on the experimental investigation, ultrasonic welding was found to be the most suitable technique for joining the proposed CSIPs.

There is strong evidence that the oil and gas industry has become increasingly interested in using pipes and risers made of fiber-reinforced polymer (FRP) composite materials. Moreover, oil and gas exploration nowadays has to be conducted in much deeper water depths (500–1500m and deeper), thus requiring more resilient and lighter materials. in this section various applications of FRP in relation to pipes and risers are discussed to familiarise the reader with various FRP and hybrid pipes. The issues affecting the long-term performance of these materials, as well as issues involved with joining pipes and risers are also covered. Finally, the recent trends related to the use of FRP for repair and rehabilitation of deteriorated metallic pipes are presented.
