Optimization of structural buildings

Optimization of structural buildings deals with a “design” of structures that minimize the construction cost and fulfill the required performance simultaneously. The performance of the different structural systems varies due to different behaviour of structures to lateral and gravitational loads. An accurate understanding of the concept mentioned above is of great importance. Our group proposed solutions and algorithms to challenging optimization problems by considering the following concepts.

Optimization methods of IDSA group lead to a tangible reduction of final structural cost and will improve structural safety and performance.


Minimization of the lateral load (such as seismic or wind) input energy


Appropriate conduction of lateral and gravitational forces to the ground


Appropriate conduction of structural failure modes to back and forth modes instead of torsional modes


Damping the seismic and wind structural energy


Considering the interaction of soil and structure


Using exact solution of engineering problems and optimizing the design of the structural concept


Implementing structural control devices

Some wrong common beliefs about optimization

these wrong beliefs include:

  • Reduction of structural capacity
  • Undesirable change of constructional materials
  • Safety reduction
  • Fall in structural performance
  • Creating architectural limitations

We in IDSA group optimize the structural design by creative engineering methods without changing the material. These methods are mainly based on the minimization of seismic structural energy and reducing the induced forces in members. These methods lead to the improvement of structural performance due to the diminishing of member forces and will not harm the structural capacity, safety, structural performance, architectural limitations and constructional materials
