Seismic design is a critical aspect of construction, particularly in regions prone to earthquakes. It is one of the fastest growing areas of engineering and is vital to the safety and long-term asset management of buildings and associated structures.
Here is an overview of our key principles and considerations in seismic design services:
- Understanding seismic hazard: We begin seismic design with a thorough assessment of the seismic hazard at the construction site, including a geological assessment of soil conditions, expected ground motion and proximity to fault lines. Since an integral part of seismic design is the assessment of soil type. Soft layers of clay and sand increase seismic loads, while hard rocks reduce them. We use all received comprehensive information to determine the appropriate Seismic Design Category (SDC) for structures, including risk analysis and creation of a risk matrix, which ranges from A (low seismic risk) to F (high seismic risk). We can also thoroughly study the information received about the condition of the soil and provide a detailed report with conclusions and recommendations on geotechnical parameters that can be used by the Client in seismic design.
- Structural design considerations: Our seismic design efforts focus on ensuring the structural integrity of buildings by considering factors such as ductility, strength, stiffness and damping. Structural systems such as load-bearing walls, moment-resisting frames, and braced frames are designed to resist lateral forces and dissipate energy during an earthquake. We also pay special attention to the building’s configuration, including its shape, size and mass distribution, which also plays a critical role in its seismic performance.
- Analysis methods: In seismic design, we incorporate various analysis techniques, including static analysis, response spectrum analysis, and time history analysis. The choice of analysis method depends on factors such as the complexity of the building, the level of seismic hazard and the desired level of accuracy. We use advanced structural analysis techniques and software for structural modeling, seismic load calculations and structural element analysis to ensure that a building or structure is designed in accordance with relevant design code requirements.
- Performance based design: In seismic design we are based on the characteristics to ensure that a building meets specific performance requirements, such as remaining functional after a minor earthquake or preventing collapse during a major one. Thus, this approach assumes the ability to assess the dynamic characteristics of a building and optimizing its behavior to achieve the desired level of resilience.
- Non-structural components: In seismic design, we also consider the performance of non-structural components such as cladding, wall partitions and engineering utilities that may be affected by seismic forces and may result in damage or failure. We recognize that the proper design and anchorage of these non-structural elements is essential to the overall safety and functionality of the building during an earthquake.
- Cost-benefit analysis: We base our seismic design decisions on a comprehensive cost-benefit analysis, considering factors such as construction costs, maintenance, insurance, and the value of the building’s functionality and resilience.
Therefore, by using these principles and considerations in construction projects, our seismic design experts can design new buildings to meet the latest design requirements related to the building’s geographic location to withstand seismic events, protect human life, and minimize the risk of structural and non-structural damage, ensuring the long-term safety and sustainability of the built environment.
