Probability Assessment of Analysis of High-Rise Buildings Seismic Resistance

Abstract

This paper presents the probabilistic assessment to analyze the resistance of the unsymmetrical effects (accidental torsional effects, soil-structure interaction, and seismic action) to symmetrical high rise buildings. The Eurocode requires that the seismic resistance of structures must be checked to the accidental torsion effects. In order to cover uncertainties in the location of masses and in the spatial variation of the seismic motion, the calculated centre of mass at each floor shall be considered displaced from its nominal location in each direction by an accidental eccentricity due to the requirements of ENV 1998. Recent advances and the general accessibility of information technologies and computing techniques give rise to assumptions concerning the wider use of the probabilistic assessment of the reliability of structures through the use of simulation methods. The possibilities of the utilization the RSM method to analyze the extensive and robust tasks in FEM is presented in the case of the buildings with central core and columns system. The deterministic and probability analysis of the seismic resistance of the structure was calculated in the ANSYS program.
