Abstract: A reconsolidated bamboo beam-column joint connected by a subassembly and a design method thereof are provided. Rectangular shear steel plates and vertical steel plates in embedded steel plates form an H-shaped section, and left and right ends of the vertical steel plates are embedded in mortises of a reconsolidated bamboo column and a reconsolidated bamboo beam respectively, thereby effectively improving bearing capacity of the joint. A half tenon is provided with an elliptical bolt hole in a penetrating manner and connected to the reconsolidated bamboo column by a bolt, and the half tenon is rotatable along a center of the elliptical bolt hole and movable along a long axis of the elliptical bolt hole, so that the energy is dissipated through friction between the reconsolidated bamboo half tenon and mortises, excellent energy consumption ability of the half tenon structure is exerted, and the anti-pulling resistance of the tenon is improved.

Abstract: A method for detecting groceries in corridor is provided, this method includes: obtaining an image collected from a corridor, performing pedestrian detection and grocery detection on the image collected from the corridor to obtain a pedestrian detection result and a grocery detection result; performing, if there is a pedestrian image in the pedestrian detection result, an image processing on the image collected from the corridor according to the pedestrian image; comparing the image that is collected from the corridor and has been processed with a preset corridor image to obtain an image similarity; generating, if there is a grocery image in the grocery detection result, or if the image similarity is less than or equal to a similarity threshold, a grocery cleaning instruction according to an identifier of corridor in the image collected from the corridor; and sending a grocery cleaning prompt according to the grocery cleaning instruction.
