摘要：Considering the nonlinearity of the material, this paper uses the finite element analysis software Abaqus to model and analyse the external prestressed concrete composite beam of corrugated steel web. In this paper, the key processing methods in the modeling process are described in detail. The whole process of loading and destroying the prestressed concrete composite beams of corrugated steel webs is simulated. The calculated load-deflection curve and load-stress increment curve are in good agreement with the author's early test results, which verifies the accuracy and reliability of the calculation analysis of external prestressed concrete composite beams of corrugated steel webs. Further analysis shows that in the calculation analysis, the secondary effect of the external prestressing tendon cannot be ignored. In addition, under the limit state, the calculated stress increment of the external prestressed tendons is smaller than the actual measurement, and the preliminary analysis may be related to the calculation of the tensile constitutive model of the concrete material. The in-depth study of the external reinforced stress increment and the transmission mechanism between the concrete and the corrugated steel web will be carried out in the following state.
