Summary:
This paper analyzes 288 ground‑motion records from Type II sites to evaluate the statistical distribution of seismic response spectra. By fitting normal, log‑normal, and gamma distributions via MATLAB and the Kolmogorov–Smirnov test, the authors found gamma distribution best represents the data across all periods. They establish dynamic coefficient spectra at 50–80% probability guarantee levels, showing that standard code spectra lack sufficient safety margins for long‑period structures over a 50‑year design life. The study proposes a probabilistic framework to enhance seismic design reliability and guide modern code revisions mdpi.com.

Summary:
Examines a 146.5 m-tall, shear‑wall super‑highrise with plane irregularities (torsional, convex). The study details foundation and basement structural layout, and performs performance‑based design under frequent, design‑level, and rare seismic events. Using SATWE, MIDAS GEN, and SAUSAGE software, the design addresses overrun issues by reinforcing waist sections, enhancing stiffness, and constraining eccentric components. Dynamic elastoplastic analysis verifies C‑level seismic performance and overall safety, promoting sustainable structural design practices thefreelibrary.com+5mdpi.com+5mdpi-res.com+5.
