摘要：
In this paper, the ultimate strength of cracked box girders subjected to torsional loading is investigated using a commercial FEA program, ABAQUS. The ultimate strength reduction characteristics of the box girders due to cracking damage as a function of crack sizes and crack locations are studied. Based on the numerical results obtained from the present study, a simple model for predicting the ultimate strength of cracked box beams under torsional loads is proposed. (C) 2012 Elsevier Ltd.
