Effective stiffness for structural analysis of buildings in earthquake

The latest trend in seismic design of structures according to Eurocode 8 implies taking into account the effect of cracking while evaluating the stiffness of reinforced concrete elements – the stiffness affects on size of seismic forces and lateral displacements. In this paper an analysis of effective stiffness of cracked reinforced concrete elements depending on the size of axial force and the amount of longitudinal reinforcement was conducted, taking into account the tension stiffening effect. The results obtained through this analysis were then applied to a seven – storey residential building.
