Abstract
A relatively simple seismic analysis technique based on the pushover analysis of a multi-degree-of-freedom model and the response spectrum analysis of an equivalent single-degree-of-freedom system, called the N2 method, has been developed at the University of Ljubljana and implemented in the European standard Eurocode 8. The method is formulated in the acceleration —displacement format, which enables the visual interpretation of the procedure and of the relations between the basic quantities controlling the seismic response. Its basic variant was restricted to planar structures. Recently the applicability of the method has been extended to plan-asymmetric buildings, which require a 3D structural model. In the paper, the N2 method is summarized and applied to two test examples.
