• Abstract:
  Studies involving the impact behavior of certain types of sign supports are described in this progress report. The progress report is presented in two parts. Part A is entitled "Phenomenological Behavior of Sign Supports, and Part B is entitled "An Analytical Study of Break-Away Sign Supports for Roadside Signs." The first part of the report is based on observations of motion picture films of twenty-seven crash tests conducted during the second year of research. Part B presents the results of a series of instrumented crash tests, comprising six in number, conducted to provide data for the development of a mathematical model to predict the impact behavior of sign supports. The development of a mathematical model expressing support post behavior is also described.
