. During the operation of boiler 1, the secondary superheater pipe elbow section failed due to explosion and leakage. In order to find out the cause of the explosion and leakage of the elbow section of the secondary superheater tube, a comprehensive test analysis was carried out on the failure cause of the elbow section of the secondary superheater tube with the appearance analysis, chemical composition analysis, microstructure detection and mechanical property detection.The results show that the leakage of the elbow section of the secondary superheater tube is due to the long-term overheating of the elbow section of the secondary superheater tube during the operation process, resulting in a serious reduction of spheroidization strength, which was not enough to withstand the leakage caused by the internal medium pressure, and the leakage of the adjacent superheater tube was caused by the leakage steam blowing away the adjacent superheater tube.

: The finite element model was established by ABAQUS software to simulate the push-out test of GFRP perforated plate connectors. The reliability of numerical simulation was verified by comparing with the test results. Then, using the strength grade of concrete and the strength of perforated rebar as the changing parameters, the influencing factors of the shear capacity of the GFRP perforated plate connectors are explored. The test results indicate that increasing the strength level of concrete, the strength of perforated rebar can improve the shear capacity of the GFRP perforated plate connectors.
