Seizmické zatížení železobetonových konstrukcí

Abstract eng:
The structural analysis in earthquake engineering is a complex task because the problem is dynamic and usually non-linear, the structural system is usually complex, and input data (structural properties and ground motions) are random and uncertain. In principle, the nonliner time-history analysis is the correct approach. However, such an approach, for the time being, is not practical for everyday design use. The simplified non-linear methods, which are, like any approximate method, subject to several limitations, provide a tool for a rational yet practical evaluation procedure for building structures for multiple performance objectives. The formulation of the methods in the acceleration – displacement format enables the visual interpretation of the procedure and of the relations between the basic quantities controlling the seismic response.
