“…Drawing from the spectral displacements corresponding to the performance points derived from the demand spectrum and capacity spectrum for moderate seismic excitations, the vertex displacements ∆ i (i = 1, 2, 3) are systematically computed using the formula (12). Subsequently, the structural displacement demand ∆ is determined by taking the square root of the sum of squares of the vertex displacements.…”

“…Nonlinear time history analyses and performance-based seismic design were conducted on steel MRFs, EBFs, and BRBFs. A simple expression linking the peak seismic layer velocity to the peak ground velocity was provided, with its efficiency demonstrated through numerical examples [12]. Additionally, steel plate shear wall structures, consisting of 4, 8, and 12 stories, were developed following the Code for Seismic Design of Buildings (GB 50011-2010) [13].…”

The design innovation of high-strength steel frames paired with D-eccentric bracing exhibits remarkable resistance to plastic deformation during seismic events. This method strategically combines regular steel connections (with yield strengths below 345 MPa) and high-strength steel beams and columns (such as Q460 or Q690, with yield strengths over 460 MPa), effectively reducing cross-sectional sizes while preserving the elasticity of non-energy-dissipating members. This configuration results in substantial ductility and superior energy dissipation capabilities. The response modification factor (R) is vital for achieving both effective and economical seismic resilience, particularly in the development of efficient and cost-effective seismic designs. However, the 2016 edition of the Code for Seismic Design of Buildings (GB50011-2010) fails to incorporate the concept of R, opting instead to apply a uniform value to all structural systems. This oversight is fundamentally flawed, necessitating a comprehensive investigation into the R value specifically for the high-strength steel frame with a D-eccentric brace. This research primarily aims to improve structural performance design, provide guidance for future projects, and encourage the adoption of this advanced seismic performance structure in earthquake-prone areas. To achieve these objectives, a performance-based seismic design approach is employed. This method involves designing structures with varying numbers of stories (4, 8, and 12), different link lengths (900, 1000, and 1100 mm), and various steel strengths (Q460 and Q690). This study uses the Incremental Dynamic Analysis (IDA) method to determine the R values for each prototype. The derived performance coefficients act as crucial references for the development of future innovative structural designs. This research greatly enhances seismic design practices and facilitates the wider adoption of high-strength steel frames with D-eccentric braces due to their outstanding seismic performance.
