In recent ten years, a number of cracking cases were reported on the in-service high-strength steel spheric tank made of 07MnCrMoVR and 07MnNiCrMoVDR steels (CF-62 steel for short) which were developed in China independently. Based on field survey, actual vessel inspection and failure analysis, it is pointed out that the quality of the steels, the problems existing in design and fabrication process and incompleteness of relevant standards are the major cause of cracking. Recommendations for cracking prevention of the high-strength steel spheric tank made of Chinese CF-62 steel are proposed.

The high strength steel wire mesh and polymer mortar reinforcement technology has the advantages of high strength, high temperature resistance,corrosion,resistant, etc. In this paper,we analysis the flexural properties of RC beams strengthened by it using ANSYS.To bear the same moment in the same area of the reinforcement steel strand, and then get effect of different span and different reinforcement methods (comparative beam, direct reinforced beams,and secondary load of reinforced beams) on flexural load-carrying capacity and deflection, then compare and analysis,and draws the conclusion which can provide reference for practical engineering.

Based on the experimental study of shear strengthened of reinforced concrete rectangular beam strengthened by high-strength steel wire mesh and polymer mortar , the finite element extended analysis was used. The finite element analysis software showed that with the increasing of the strand dosage and reinforcement strand length,the shear strength and stiffness of strengthened members improved . However,with the increasing of shear span ratio , the shear strength and stiffness reduced obviously .
