Because PBSD utilizes rigorous earthquake analyses that go beyond the standard Building Code requirements, engineers can innovate and adopt more creative approaches to building design. For instance: 

Example: High-Rise Building Design in a Seismically Active and Wind-Prone Region

Code-Based Design:
In a region prone to both earthquakes and strong winds, building codes typically require the use of a dual structural system—combining a moment-resisting frame with a shear wall system. This approach is intended to ensure that the building can withstand both seismic and wind forces. However, the code does not account for the specific interactions between these forces in relation to the building's unique geometry and location. As a result, the design might include overly robust elements that unnecessarily increase the building’s weight and construction costs.

PBD Seismic and Wind Approach:
Using PBD, engineers can simulate the combined effects of seismic and wind forces on a specific high-rise building. These simulations allow for a more nuanced understanding of how the building responds to different types of loading. For example, the PBD approach might reveal that the shear walls can be strategically placed to not only resist seismic forces but also optimize wind load distribution across the building. By fine-tuning the placement and design of these structural elements, the engineers can reduce the overall material usage, making the structure lighter and more cost-effective.

Additionally, PBD might show that by adjusting the building’s damping system—such as by incorporating tuned mass dampers—the structure can effectively manage both seismic and wind-induced vibrations. This integrated approach can enhance occupant comfort during wind events and improve the building's seismic resilience, without the need for overly conservative structural elements that a code-based design might require.

in this example, PBD allows for the creation of a more efficient, cost-effective, and performance-optimized design by taking into account the specific interactions between seismic and wind forces on the building. Instead of adhering to the blanket safety requirements of a code-based design, which may result in an unnecessarily heavy and expensive structure, PBD tailors the design to the building’s unique characteristics, delivering better overall performance while minimizing costs.
