Overview
Imperial and Arup have collaboratively pioneered a novel design methodology for tall structures. This approach integrates the building's self-weight as a mechanism to diminish oscillatory movement caused by high winds and seismic activity. The design draws conceptual inspiration from traditional Japanese pagodas.
Research Context
The impetus for this research stems from the necessity to develop more resilient and resource-efficient tall building designs. Traditional Japanese pagodas, known for their stability against natural forces, served as a foundational inspiration for re-evaluating conventional structural engineering principles in contemporary high-rise construction.
Approach
The developed approach by Imperial and Arup focuses on leveraging the inherent mass of the building itself. This strategy aims to counteract dynamic forces such as those exerted by high winds and earthquakes. By integrating principles observed in pagoda architecture, the method seeks to passively control structural movement rather than relying solely on external or active damping systems.
Findings
The new design approach demonstrated a capacity to reduce tower sway. This reduction in movement is attributed to the system's utilization of the building's own weight. Concurrently, the methodology indicated a potential for decreasing material requirements in construction.
Why This Matters
This design concept contributes to making tall buildings safer by improving their stability against high winds and earthquakes. Additionally, the approach offers benefits in terms of sustainability and cost-efficiency by reducing carbon emissions associated with construction and lowering overall construction expenses due to decreased material usage.
