Abstract: A T-shaped shear wall module including a straight pattern plate, two L-shaped pattern plates with a same structure, and connectors. Each of the two L-shaped pattern plates includes a first pattern plate and a second pattern plate which are perpendicular to each other. In a direction perpendicular to the straight pattern plate, the two first pattern plates are arranged in parallel to each other and both extend in a direction away from the straight pattern plate, and a plurality of connectors are rigidly arranged between two first pattern plates. Along a direction parallel to the straight pattern plate, two second pattern plates are coplanar and extend in opposite directions, and a plurality of connectors are rigidly arranged between the straight pattern plate and the two second pattern plates. The present application also provides a shear wall and a construction method thereof.

Abstract: An air supply device with an annular air outlet and a design method thereof are provided. The device includes an air delivery section arranged in a horizontal plane and communicated with a plurality of air-out sections, wherein an axis of each of the plurality of air-out sections is in a vertical direction; the air delivery section and the plurality of air-out sections are respectively provided with air return ducts communicated with each other, the air return ducts each have a fresh air duct provided therein; an axis of the fresh air duct is parallel to an axis of corresponding air return duct of the air return ducts, and the fresh air duct and the corresponding air return duct are equal in length, the plurality of air-out sections are arranged above office cubicles in a room.

Abstract: An adaptive loading method for real-time hybrid simulation testing based on a space frame model. The system initial delay is controlled to be close to 0 before the loading of seismic wave by a dual compensation strategy for the initial delay based on the initial delay compensation and the adaptive loading segment, thereby solving the problem of insufficient estimation and compensation of the initial delay in the real-time hybrid simulation. In addition, the test substructure of the space frame model is equated as a test element, and the overall displacement response corresponding to the test substructure in the overall model is converted to the actual loading relative displacement of the test substructure by using the signal conversion module, thereby realizing the real-time loading of the large-scale spatial frame model with great rigidity.

Abstract: A composite ozone flotation integrated device may include a cylinder body, an intermediate cylinder, and a central cylinder which are coaxial. The cylinder body and the center cylinder have a common bottom. The cylinder body and the intermediate cylinder have a common top. The intermediate cylinder is arranged on support channel steel between the cylinder body and the center cylinder. A top of the center cylinder is in the intermediate cylinder. The top of the center cylinder is open-mouthed. An upper part of the cylinder body is provided with a drainpipe. The top of the cylinder body is provided with an inner cylinder exhaust pipe and a slag discharge pipe. An upper part of the intermediate cylinder is provided with an outer cylinder exhaust pipe. A lower part of the center cylinder is connected to a water inlet pipe, a dissolved gas inlet pipe, and a venting and sludge-discharge pipe.
