| Abstract: | Combined with the engineering of demolition blasting for a large-scale steel structure, the structure pretreatment, the influence of treatment and design of the pretreatment plan are investigated and the pretreatment plan should be based on the structure bucking analysis. The emphasis is laid on the calculation of the bucking loads of the complex structure and irregular members. The finite theory of the bucking analysis is used to calculate the bucking eigenvalue of the treated steel bent structure by an ANSYS software. |
