Abstract

Recently, as a result of seismic events occurrences in Italy, building safety has become a topic of considerable interest. Most of existing reinforced concrete frame buildings designed for vertical loads only and without construction details, which guarantee ductility and dissipative capacity. Then it is necessary to develop a reliable and practical analysis procedure for professional use.

This is confirmed by intense research activities to identify the capacity and the safety level of existing structures. Between existing approaches, the Incremental Dynamic Analysis (IDA) is considered to be one of the most accurate methods to estimate the seismic demand and capacity of structures. However the executions of many nonlinear response history analyses (NL_RHA) are required, therefore approaches non-linear static analyses based are studying to aim less onerous methods. The research discussed in this paper deals with the proposal of an efficient Incremental Modal Pushover Analysis (IMPA) to obtain capacity curves by replacing the nonlinear response history analysis of the IDA procedure with Modal Pushover Analysis (MPA). Finally, these approaches were applied to an existing case study that is a concrete framed building of strategic relevance.
