Towards the Bled Workshop in Future

Abstract

The author sincerely expects further development of the Bled workshop and he would like to refer to some basic items important to keep continuation. One of the goals of the performance-based design is to control structural damage under earthquakes within a certain limit. Energy concepts in earthquake engineering can provide plausible way to achieve this goal. In other words, the performance-based design must be eloquently spoken by a technical language and the balance of energy can be a key concept to establish its grammatical construction. The mixed structure develops the most preferable structural mechanism under earthquakes due to collaboration between the elastic and elastic-plastic element. The concept is applied to different types of structures – base-isolated structures, seismically controlled structures, reinforced concrete shear walls and diagonal bracing systems in steel structures.
