The design of a 32-story tower with a height of 140 meters represents one of the most complex and challenging projects in the field of structural engineering. This project, in addition to its complex geometric features and seismic resistance requirements, will undergo a performance-based design in its second phase to ensure optimal behavior under seismic forces and the overall structural response over time.
Key features and technical challenges include:
- Irregular Geometric Design: The tower’s floor plan features significant variations in height and area between floors. This asymmetry demands more complex analyses and precise modeling, particularly in simulating the building’s seismic behavior. The distribution of lateral loads and controlling their variations between floors is one of the main challenges.
- Advanced Structural System: The project includes a combination of moment-resisting frames and shear concrete walls, specifically designed to withstand seismic forces. The system not only provides stability against seismic forces but must also maintain flexibility to respond to changes in lateral loads and structural alterations over time. Detailed design and advanced simulations are critical at this stage.
- Hybrid Foundation System: Given the unique soil conditions, the foundation system incorporates wide foundations (mat foundation), semi-deep piles, and strip foundations. This system ensures stability against differential settlement and seismic forces. The mat foundation distributes seismic forces evenly while maintaining stability during horizontal loads.
- Slanted Corridor Design: The design of the slanted corridor between floors 5 to 18 introduces unique structural challenges. Ensuring safe connections and maintaining the system’s performance during seismic events is a critical concern, requiring precise execution in this area.
- Performance-Based Design in Phase Two: The second phase of the design will focus on performance-based design to optimize the building's response to dynamic and seismic forces. The rigid diaphragm will play a crucial role in controlling floor displacements and strengthening the entire structure. Its interaction with the shear concrete walls will help distribute lateral forces uniformly, enhancing the building's stability and reducing floor displacements, especially near shear walls. This performance-based design ensures that the structure will function optimally under unpredictable forces and adapt to changes over time, including variations in stiffness or soil settlement.
This project aims not only to meet the highest engineering standards but also to implement innovative architectural and structural concepts that will significantly influence the development of construction in the region.
