Temperature Profiles of Concrete Members in Various Geographical Regions: Guidelines for Installation and Design of Bonded Anchors Considering Climate Change Scenarios

Abstract

Post-installed bonded anchors are used to connect structural and non-structural members in a variety of applications in concrete structures. The performance of bonded anchors can be influenced by several different parameters. One of the most important aspects that directly affects the bond strength of the adhesive anchor in both the short and long term, as well as various processes that occur at the material level of the adhesive is related to the temperature conditions during installation and over the design service life of the fastener. For this reason, different adhesive systems have different temperature ranges defined by the manufacturer. These temperature ranges include the maximum short-term temperature and the maximum long-term temperature, which represent the upper limits of the temperature range in which the fasteners can maintain their structural integrity and performance without significant degradation. Therefore, the service life of adhesive anchors is designed by considering the various environmental conditions of the region in which the structure is located. This contribution introduces a method for defining the temperature ranges taking into account historical data and climate change scenarios.
