ABSTRACT

With the advancement of science and technology today, detailed analysis of the interaction between materials is no longer a barrier to creating structures that ensure both resistance, economy and highly aesthetic Based on Abaqus software, with the features of solving linear and nonlinear problems related to statics, dynamics, thermodynamics, etc., this thesis analyzee the torsional behavior of concrete-filled steel pipes Concrete Filled Steel Tubes ± (CFST) has considered the effect of corrosion defect on steel pipe, penetrating the Shell The theoretical analysis and finite element analysis on Abaqus software, the model has been verified for its correctness by re-simulating the CFST studies of author Jehyun Beck and Osamu Kiyomiya [2], the results have a high concordance The thesis has developed a series of studies on the behavior of corrosion defects on CFST structures through changing the size of defects Based on previously established and recognized research results (model of concrete materials, steel materials, interaction coefficient between concrete core and steel pipe, .), CFST structure with large defect size used to investigate torsional resistance and evaluate results
