Adan Engineering works jointly with building component manufacturers and research institutions to evaluate earthquake effects on structures and to develop appropriate building code provisions.  Current areas of research and testing include the following:

  • Behavior and seismic design of steel moment-resisting connections subjected to cyclic loading.
  • Development of finite element models for computational analysis with an emphasis on nonlinear behavior.
  • Earthquake-resistant design of steel and composite structures, with an emphasis on connection behavior and design.
  • Post-earthquake evaluation of steel moment frame buildings.
  • Evaluation, rehabilitation, and repair of existing steel moment frame structures.
  • Evaluation of cast high strength steel connectors.
