Advanced structural engineering for dynamic loads
All structural design involves dynamic loading situations to some degree. Standard engineering practices typically address dynamic loads such as wind, human- or machine-induced vibrations, and seismic activity. However, certain scenarios involve complex or extreme dynamic behaviour that falls outside conventional design approaches.
Explosions, impacts or high-energy vibrations can cause rapid structural responses that require advanced analysis and specialised engineering strategies. In these situations, advanced and high dynamics engineering becomes essential to ensure safety and performance.
When low-probability events matter
Even very low-probability load scenarios can have such severe consequences that they carry unacceptable high risk if not properly addressed in the design process. Accidental scenarios such as gas explosions in industrial environments or impacts from falling objects can cause significant damage. At the same time, intentional threats such as malicious attacks involving explosive devices or vehicle impacts are increasingly considered in security-driven design.
These high dynamic events require specialised modelling and design approaches to assess risks and define appropriate mitigation strategies.
Advanced and high dynamics
High dynamic loads behave fundamentally differently from static loads. They occur suddenly, evolve rapidly and interact with structures in complex ways.
High dynamic analyses must consider:
- Wave propagation effects
- Nonlinear material behaviour
- Geometrical nonlinearities
- Rapid energy transfer within structures
While simplified analytical tools can , advanced numerical simulations are often required. Using methods such as finite element modelling and specialised simulation tools, Sweco delivers accurate insights into structural behaviour under extreme conditions.
Our services
Our team combines simplified engineering methods with advanced simulations to deliver efficient and reliable designs for extreme dynamic events.
Typical services include:
- Blast and impact load analysis
- Structural response and damage assessment
- Blast-resistant and impact-resistant design solutions
- Design of protective measures and mitigation strategies
- Retrofitting and strengthening of existing structures
Through close collaboration with multidisciplinary teams within Sweco, we ensure fully integrated solutions. We also work closely with Sweco’s specialised simulation experts in Finland, providing access to an extended knowledge base and international experience.
Client benefits
By integrating advanced and high dynamic considerations early in the design process, organisations can:
- Protect human life and safety
- Reduce structural damage and financial risks
- Limit environmental impact
- Ensure business continuity and reduce downtime
- Safeguard reputation and public trust
Early integration also leads to more cost-efficient solutions, as protective measures can be embedded directly into the design.
