  This paper proposes the simulation of structured behaviors in a crowd of
virtual agents by extending the BioCrowds simulation model.
  Three behaviors were simulated and evaluated, a queue as a generic case and
two specific behaviors observed at rock concerts. The extended model
incorporates new parameters and modifications to replicate these behaviors
accurately. Experiments were conducted to analyze the impact of parameters on
simulation results, and computational performance was considered.
  The results demonstrate the model's effectiveness in simulating structured
behaviors and its potential for replicating complex social phenomena in diverse
scenarios.
