Dear All,
IStructE Regional Group Committee is inviting you to an online webinar by Ms. Vijayashree Ballari, National Specification Engineer – HILTI Emirates, on the topic "Post installed rebar – Current design method and it’s limitations; TR-069 the new design method and it’s benefits”.
The objective of post-installed or bonded-in reinforcement in an existing reinforced concrete structure is to provide a connection between a new concrete element and the existing structure that is similar in strength and stiffness as cast-in reinforcement. The technology of post-installed reinforcing bars is gaining increasing importance since these bars are being used frequently in horizontal, vertical, and overhead applications in rehabilitation and strengthening of existing structures. Post-installed bars are also used in specific situations in new construction to simplify construction procedures and provide flexibility in design and construction. In cases where the tensile forces must be redirected, the cast-in connecting bars are bent in the pertaining direction. Bonded-in reinforcement, however, can only be installed with straight bar ends in drilled holes by means of a bonding agent, often a resin-based product”
This Webinar will be focused into the previous design method for post-installed rebar connections according to EOTA TR 023, accordance with EN 1992-1-1 and the new Technical Report TR 069, published in 2019 “Design method for anchorages of post-installed rebar with improved bond-splitting behavior as compared to EN 1992-1-1” which allows for the design of post-installed, moment-resisting reinforced concrete connections under static loading conditions without using a splice configuration.
The design is based on the hierarchy strength design principle, i.e., the lowest resistance of the individual failure modes is decisive. Yielding of the steel, concrete cone failure and bond-splitting failure of the post-installed rebar connection must be verified. In addition, the requirements of EN1992-1-1 in terms of minimum anchorage length must be fulfilled.
All in all, A CODE COMPLIANT DESIGN FOR ALL APPLICATIONS, POTENTIAL FOR OPTIMIZATION, ALL IN ONE Software: PRODUCTIVITY.
