Nonlinear finite element analysis of bond-slip performance of recycled aggregate concrete filled circular steel tube
Source abstract
Abstract
The aim of this paper is to solve the problem of extremely difficult, low work efficiency and low accuracy of finite element analysis (FEA) when considering the bond-slip performance of recycled aggregate concrete filled circular steel tube (RACFCST). Toward this end, spring elements generation software for RACFCST V1.0, parametric modeling software for push-out test of RACFCST V1.0, and the Nodes selection program for RACFCST were developed. The FEA model of the RACFCST push-out test was established with the software and the model was calculated in ABAQUS, the calculated results were compared with the existing test results. The results show that: (1) The FEA model of RACFCST components considering bond-slip can be efficiently, accurately and simply established by spring elements generation software for RACFCST V1.0; (2) The results of FEA were found to be in good agreement with the experimental data, and spring elements generation software can solve the problem of FEA of RACFCST considering bond-slip performance; (3) The modeling efficiency and accuracy of RACFCST components can be greatly improved by Parametric modeling software for push-out test of RACFCST V1.0; (4) The efficiency and flexibility of selecting nodes during post-processing is greatly improved by Nodes selection program for RACFCST V1.0.
