Although box columns offer significant advantages, they also have limitations, particularly regarding the design of connection plates and their shear strength at connections. The introduction of ConXL, recognized as a prequalified solution under AISC regulations, addresses these issues. This well-known connection offers several benefits, including improved industrialization and quality control, elimination of continuity plates, faster construction times, and streamlined inspections.

1 Introduction For any structures under seismic loading, the stiffness, strength, and energy dissipation are the most important parameters to have a desirable performance. Among the conventional steel structures such as the moment resisting frame (MRF), concentrically braced frame (CBF), and eccentrically braced frame (EBF), the CBF system pertains higher elastic stiffness and ultimate strength but suffers low energy dissipation capacity.

In this paper, an innovative damper made of low yield point (LYP) steel compound of double corrugated plate and flange plates to form an I-shaped damper was considered parametrically and numerically. This damper pertain to easy fabrication and replacement after a severe earthquake. The proposed damper is expected to yield while elements outside the damper remain elastic. Consequently, it acts as a ductile fuse that was confirmed in this study.
