In order to research the concrete archaized buildings with lintel-column joint, 2 specimens were tested under dynamic experiment. The failure characteristics, skeleton curves, mechanical behavior such as the load-displacement hysteretic loops, load carrying capacity, degradation of strength and stiffness, ductility and energy dissipation of the joints were analyzed. The results indicate that comparies with the lintel-column joints, the loading capacity and energy dissipation of the concrete archaized buildings with dual lintel-column joints are higher, and the hysteretic loops is in plump-shape. However, the displacement ductility coefficient is less than that of lintel-column joints. Both of them of the regularity of rigidity degeneration are basically the same. Generally, the joints have the good energy dissipation capacity. And the concrete archaized buildings with lintel-column joints exhibit excellent seismic behavior.

Based on 5G and IoT technology, this study addresses the issues of manual control dependency, poor reliability, and high labor costs in traditional ceramic kiln exhaust cover operations. An intelligent control system for kiln exhaust covers was designed in this paper. The system employs temperature measurement devices to monitor the internal temperature of the kiln in real time. A controller automatically operates the actuator to open or close the kiln exhaust cover based on temperature measurements. Additionally, the system integrates data transmission units and cloud services, enabling remote monitoring of kiln temperature and historical data storage. Experimental results demonstrate that the system effectively reduces labor costs and significantly enhances the IoT capabilities of kiln operations.

Glass is widely used in impact protection, high-tech industry and other fields.The initiation and growth of cracks in glass under the action of SHPB were studied by experimental research, theoretical analysis and numerical simulation. The theoretical analysis shows that in the impact crushing process, the failure front divides the sample into broken zone and intact zone. According to the Griffith energy balance theory, most cracks propagate along the specimen axially, and the initiation and growth of cracks must overcome the unrecoverable surface energy. The JH-2 model is used to simulate the evolution of impact microcracks in SHPB test of float glass. The results are in good agreement with the experiments, and the tensile stress is more likely to cause crack propagation.
