Design method of modular bi-directional load-bearing and energy dissipating joints in the context of intelligent construction

The requirements for structural performance and seismic performance in the field of civil engineering are increasing. Traditional building structures have certain limitations in extreme conditions such as earthquakes. Therefore, this study discusses the design of modular bi-directional load-bearing and energy dissipating joints in the context of intelligent construction to improve the seismic performance of buildings. The study designs vertical joints and bi-directional joints, and the test results show that the hysteresis curve of the joints is hump-shaped, exhibiting excellent plastic deformation and energy dissipation performance. The introduction of oblique stiffening ribs in the vertical joints significantly improves the load-bearing capacity, and there is no significant decrease in load-bearing capacity when loaded to approximately 32 mm. The maximum energy dissipation coefficient of vertical joint specimen 1 is 1.485. For specimen 2, the maximum values is 1.801, and for the bi-directional joints, the maximum values is 2.156, demonstrating excellent energy dissipation capability. In conclusion, this research is of great significance for the combination of modern building engineering technology and intelligent construction, providing strong support for the seismic performance and overall safety of building structures.
