Web-bar-free prestress self-maintaining combination beam based on permanent post-tensioning prestress UHPC sleeving formwork and construction method

The invention discloses a web-bar-free prestress self-maintaining combination beam based on a permanent post-tensioning prestress UHPC sleeving formwork and a construction method. The combination beamcomprises a top plate, the sleeving formwork and self-maintaining concrete. The sleeving formwork comprises a base plate, a web formwork and an end head inserting plate. The base plate, the web formwork and the end head inserting plate are formed by prefabricating ultra-high-performance concrete. An inserting groove shaped like a hollow square encircled by another hollow square is prefabricated in the upper surface of the base plate. According to the combination beam, the UHPC serves as permanent formwork materials, the self-maintaining concrete fills an inner cavity of a web body, traditional hoops are removed, the material characteristics of the UHPC and the concrete are brought into full play, the beam structure form is optimized, the link of concrete manual maintaining is omitted, andmeanwhile, the problem that a pure-prestress UHPC beam is high in manufacturing cost is solved. The combination beam is applicable to assembly type construction and can be applicable to structures such as I-shaped beams and box girders. According to the construction method, the construction technology is simple, the construction efficiency is high, and the problem that the construction period ofa traditional prestress concrete beam is long can be solved.

Webshell detection method based on image analysis, terminal equipment and storage medium

The invention relates to a Webshell detection method based on image analysis, terminal equipment and a storage medium. The method comprises the following steps: S1, collecting a plurality of normal and abnormal Webshell samples; S2, according to the collected Webshell samples and the Opcode sequence and the Opcode frequency of the Webshell to be detected, generating a corresponding RGB image; S3, calculating the distance between the RGB image of the to-be-tested Webshell and the RGB image of each Webshell sample, sorting the Webshell samples according to the sequence of the distances from small to large, selecting the first N Webshell samples from the sorting result, judging the types of the first N Webshell samples, and taking the type with the maximum corresponding number as the type of the to-be-tested Webshell. According to the method, the malicious behavior of the Webshell is represented by the Opcode feature, the two-dimensional gray level image is generated by using the Opcode sequence, and then the RGB image is synthesized by combining the gray level image generated by the Opcode frequency, so that the malicious behavior of the Webshell can be represented more completely, and the detection performance is improved.
