Abstract:
Various models are used in the design of concrete brackets. This paper demonstrates the application and evidence of the truss analogy. Section 1 gives a short summary of previous work and proposed design models. In Section 2, basic structural and mathematical models for a truss analogy are outlined, and explicit capacity formulas are developed. The failure modes are discussed. In Section 3, test series from three different investigations are analyzed and calculated according to the formulas developed in Section 2. Section 4 contains a recommended design procedure. Section 5 gives recommendations for the detailing of brackets.
