Abstrakt: Because buildings are easily damaged and collapsed by earthquake disasters, a study on the seismic performance of prefabricated reinforced concrete beam joints based on the Internet of Things has been proposed. Side joints with the largest bottom column section and the largest axial compression ratio of 100 m high prefabricated reinforced concrete structure were selected for the test. The test loading scheme is completed through the test loading device and the test loading system. An logging while drilling wave is selected as the test-simulated seismic wave, and the column axial force, hysteresis curve, displacement point, strain force, and crack position are taken as the main measurement contents. To do this, the DH-3816 data collection was completed based on the Internet of Things and the test data were recorded by DH-3816 data acquisition system. The results show that the proposed method consumes much energy and has high ductility under a low cycle reciprocating load. The bearing capacity in yield state, limit state, and failure state is better, and the degradation trend of strength and stiffness is gentler. Fuzzy optimization is used to test the viability of the proposed mechanism and the results are promising. [ABSTRACT FROM AUTHOR]
