Abstract:
The proper design and execution of joints is one of the basic preconditions for efficient functioning of precast concrete frames. Headed reinforcement bars are an efficient technique to anchor tensile forces in beam-to-column joints. In comparison to traditional anchorage techniques that consist in developing tensile bars in the form of a bend or a hook, headed bars allow for optimization of the amount of steel and prevent congestion of reinforcement in the column. The present paper deals with tests of short headed bars anchoring tensile forces in compact columns. Practical benefits yielding from the research are shown on examples of industrial building products.
