Effects of stiffness reduction on seismic capacity of buildings

Tomislav Franković, Nino Mahmutović, Mehmed Čaušević

Abstract

Results obtained by analysis of two typical structures are presented. The value of shear stiffness, or stiffness to bending of structural elements (beams or walls), was varied during this analysis. The following question was answered: why did European Standard EN 1998-1:2004 set the element stiffness reduction to fifty percent of the initial value, what happens if such limit is exceeded, how is the relevant load combination type influenced by stiffness reduction, and what is the difference in the quantity of reinforcement obtained according to linear methods, if the reduction of stiffness is, or is not, taken into account.

Keywords
nonlinearity, reduced stiffness, load combination, response spectra, limit state of serviceability
