In this study, we aim to investigate the interaction between alkali-silica reaction (ASR) expansion and multi-directional reinforced steel bars, clarify weakening mechanism of bond performance under influence interaction. First, a series pullout specimens considering bar diameter stirrup number were prepared then different degrees accelerated ASR test quantify restraint effect bars. After test,...

A knowledge on the pullout forces of degradable craniomaxillofacial screws is essential in designing pediatric cranial implants. Herein, four non-identical commercially available composed different aliphatic polyesters were fixated to 3D-printed poly(l-lactide) screw hole test rig and onto a bone substitute material using manual tapping ultrasonic welding fixation techniques. method for mechani...

The toughness of composite materials is size dependent below a critical load transfer length (lT). Fiber-reinforced viscoelastic polymers are uniquely suited to study the size-limited regime because lT these soft composites can be as high several centimeters, in contrast traditional where extremely small, allowing large window for macroscale characterization. In this work, we elucidate paramete...

Recently, the use of headed bars as mechanical anchorage in reinforced concrete beam-column joints has increased rapidly. This type is used for T-shaped beam and exterior column at middle floors L- rooftops buildings. However, few experimental data are available regarding capacity embedded L-shaped joints. Nine pullout tests conducted to investigate Parameters affecting capacity, such diameter,...

This paper presents an experimental study on the pullout behaviour of inclined shallow plate anchors subjected to axial pull in sand. The 1g model tests were performed examine effects anchor inclination and sand–anchor interface conditions load–displacement response associated failure deformation mechanisms at various embedment ratios sand densities. capacity was found increase continuously wit...

There is limited research on the bond behavior of NSM strips embedded in corroded/cracked reinforced concrete (RC). Therefore, this study was initiated to evaluate between RC and strips. The test specimens consist two prisms (reinforced plain) mounted from opposite sides with After 28 days moisture curing, twenty-four were immersed saline solution exposed three accelerated corrosion levels stee...
