An experimental study for seismic reinforcement method on existing cylindrical steel piers by welded rectangular steel plates

Steel-concrete interface skid resistance properties have been studied by orthogonal test. Three factors are considered, including glue amount, silicon carbide mesh, and amount of silicon carbide. For each factor, five levels are selected. Through comparative analyses of the experiment results for each factor and the combinations of the levels of the factors, the combination with the optimal interface skid resistance was obtained. The friction coefficient with consideration of glue cohesive force was also determined. The research results provide references for structure strengthening using adhered steel plates and external prestressing.

Rotary kin shell is welded by cylindrical steel plates. Crack propagation of weld toes near supporting rollers until final fracture is the main failure form. Based on fracture mechanics, an overall intensity factor with regard to circumferential stress, concentrated stress, residual stress, and temperature stress is used to asses the crack growth. Under complex overloading conditions, the major factor, namely, circumferential stress across shell, is calculated by using finite element (FE) code ANSYS. Concentrated stress, residual stress, and temperature stress play a major role in the fatigue growth behavior, thus their effects are considered in a theoretical analysis to be included in the overall intensity factor. A certain extent good lifetime results are obtained compared with practical observation. This paper presents a reasonable procedure to evaluate propagation lifetime of weld shell, and the results are quit significant for equipment daily maintenance of rotary kiln.
