Cosic M., Brcic S.: The Development of Controlled Damage Mechanisms-Based Design Method for Nonlinear Static Pushover Analysis, Facta Universitatis, Series: Architecture and Civil Engineering, Vol. 12, No. 1, 2014. pp. 25-40.
This paper presents the original method of controlled building damage mechanisms based on Nonlinear Static Pushover Analysis (NSPA-DMBD). The optimal building damage mechanism is determined based on the solution of the Capacity Design Method (CDM), and the response of the building is considered in incremental situations. The development of damage mechanism of a system in such incremental situations is being controlled on the strain level, examining the relationship of current and limit strains in concrete and reinforcement steel. Since the procedure of the system damage mechanism analysis according to the NSPA-DMBD method is being iteratively implemented and designing checked after the strain reaches the limit, for this analysis a term Iterative-Interactive Design (IID) has been introduced. By selecting, monitoring and controlling the optimal damage mechanism of the system and by developed NSPA-DMBD method, damage mechanism of the building is being controlled and the level of resistance to an early collapse is being increased.
