Скачать или смотреть The Coefficient Alpha Setup in High-Strength Concrete

Presented By: Nilde Maci, University of Stuttgart

Description: Many studies have been conducted to find the coefficient alpha setup for adhesive anchors. This paper focuses on the determination of alpha setup in high-strength concrete. For this purpose, tests with an epoxy adhesive system were performed under both confined and unconfined setup at the Institute of Construction Materials (University of Stuttgart). Two different steel elements were considered, namely threaded rods and reinforcing bars with a diameter of 12 mm, respectively. The impact of various parameters including embedment depth, support diameter, and bond length, was observed. The findings indicate that alpha setup varies between 0.57 and 0.92 with an average value of 0.75, which coincides with the recommended value as stated in the current guidelines.
