This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...

The production of carbon fiber-reinforced plastic (CFRP) is currently changing from a highly manual and expensive to an automated process. However for automated production of CFRP parts new sensor systems for quality control are required. In this article we present a photometric stereo inspection system that is able to automatically evaluate critical quality criteria of carbon fiber fabrics. Ba...

This paper offers a detailed, quantitative and exhaustive experimental comparison in terms of mechanical properties of three different layouts of carbon composite materials (CFRP) used to strengthen existing old timber beams highly affected by diverse natural defects and biological attacks, testing the use of pultruded laminate attached on the tension side of the element (LR), CFRP fabrics tota...

A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, which is composed of twelve modules consisting of lightweight carbon fiberreinforced polymer (CFRP) sandwich construction. The modules are fabr...

The strengthening of steel structures using externally bonded (EB) carbon fiber-reinforced polymer (CFRP) laminates has gained popularity due to the advantages such as their high strength-to-weight ratio and corrosion resistance. Even though previous studies showed application EB CFRP can enhance fatigue performance cracked plates, little is known regarding high-cycle CFRP-to-steel joints. As d...

This article investigates the potential detrimental effects of cyclic load during installation externally bonded (EB) carbon fiber-reinforced polymer (CFRP) on a damaged reinforced concrete (RC) structure. Four RC specimens were tested in three point bending to study consequences crack opening-closure epoxy-curing period. A first specimen (without CFRP) was loaded monotonically up failure serve...
