Performance-Based Seismic Design (PBSD)

Wiratman implements Performance-Based Seismic Design (PBSD) across its projects, particularly for supertall buildings, as part of its commitment to innovation and structural safety. This approach focuses on designing buildings based on expected seismic performance rather than relying solely on prescriptive code requirements.

A notable example is the Autograph Tower project. It is the first supertall and tallest building in Indonesia. Utilizing advanced nonlinear modelling, time-history analysis, and close collaboration with peer reviewers, Wiratman delivered an efficient, resilient, and technically robust design. Other notable projects that applied PBSD include Two Sudirman, Ciputra Tower, and Wisma Sudirman.

While PBSD is especially relevant for tall buildings, it also provides significant advantages for essential facilities such as hospitals, data centres, and public infrastructure. By adopting this approach, Wiratman enables clients to achieve high structural performance, cost efficiency, and long-term sustainability while meeting evolving safety and regulatory standards.
