This study investigates the flexural behavior of reinforced concrete beams strengthened with near surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars. A total of five concrete beams with a length of 2100 mm were prepared with different

Superelastic shape memory alloys (SMAs) are metallic alloys that can recover their nonlinear deformations upon unloading. The use of SMAs in cementitious composites as fibers can enable crack recovery and re-centering capabilities. In this study, the

Fiber reinforced polymer (FRP) composites have been increasingly used in engineering applications due to their lightweights, high strength, and high corrosion resistance. However, the conventional FRPs exhibit brittle failure at relatively low ultima

This paper discusses vibration serviceability assessment of a highly trafficked local footbridge based on the experimental tests and analytical studies. The selected bridge is an approximately 60 m (196 ft) long multi-span steel structure with a cont

One of the main factors that lead to the deterioration of reinforced concrete structures is the corrosion of reinforcing steel. The aluminum alloy (AA) bars, which have favorable characteristics such as good ductility, low specific weight, good corro

Graphene nanoplatelets (GNPs) have the same chemical structures as carbon nanotubes but their internal structure consists of multiple layers of graphene with thicknesses of only a few nanometers. Due to their increased thickness, GNPs are less prone

In this paper, two types of mechanical anchorage systems for shape memory alloy (SMA) cables are developed and their performance and feasibility are experimentally evaluated under various loading conditions. First, the detailed descriptions of two an
