Sažetak
Pushover method is a practical procedure for comprehensive nonlinear analysis of structures subjected to seismic action. Application of this method, in accordance with the Eurocode 8 rules and due to engineering simplicity, favours application utilizing the first mode. Aim of research presented in this paper was to find the influence of multimodal combinations in assessing the bearing capacity of reinforced concrete (RC) frames and walls. This paper presents a procedure in which the most extreme state is defined by the lowest ground acceler- ation caused by a predetermined shape of an elastic spectrum. Extreme bearing value is ob- tained by the envelope principle. Mode shapes and period sizes are determined on a linear elastic model while the limit state of the load bearing system is evaluated in a nonlinear state of structures. Results of the analysis show that influences of higher modes are significantly bigger and that the safety/reliability, indicated by criteria for the target displacement, in ac-cordance with Eurocode 8 (Annex B), is not achieved. Inclusion of higher modes, in some presented examples, decreases the limit ground acceleration by more than two times, which is significantly less favourable than the target displacement criteria.
