doi:10.3969/j.issn.1000-1565.2022.01.001

Abstract

Abstract: The uncertainty of the basic material parameters of the structure will make the seismic capacity of the structural members have certain discreteness. Based on ABAQUS and OpenSees platform, the numerical simulation of reinforced concrete frame columns is carried out in this paper, and the validity of the model is verified by comparison with the experiment. On this basis, the influences of material properties and geometrical dimension parameters of members are further considered, and the corresponding probability eigenvalues and probability distribution models are given. The results show that the maximum shear force of column members can be described by normal distribution, while the displacement can be described by lognormal distribution with some errors. Therefore, the analysis of structural uncertainty is particularly important.

Key words: reinforced concrete, parameter uncertainty, randomness, hysteretic performance, frame column
