Area of expertise
Welcome to the Institute of Statics, Structural Dynamics, System Identification and Simulation (I4S) at the HTWK-Leipzig Faculty of Civil Engineering. Our pages are intended to give you an overview of our research activities and teaching content.
It is state of the art in engineering to take a holistic view of the planning and management of structures - in civil engineering, plant engineering and mechanical engineering.
The service life of an engineering structure can be classified into four significant phases: Planning, construction, utilization and dismantling.
The I4S Institute focuses in particular on the first three phases.
Traditionally, in the planning and construction phase, statics and dynamics form the basic knowledge in research and teaching in order to guarantee the safety, serviceability, economic efficiency and other special requirements of the structures.
Modern calculation methods are used here to simulate all the necessary conditions of the first two phases in a problem-specific manner and thus support the engineer in his decision-making process.
The methods and models for simulation are based on the principles of mechanics, applied mathematics and numerics.
In modern times, the use phase, during the service life of a technical construction, is of innovative importance due to the possibilities of sensor technology and digitalization.
The classic engineering models can be verified and optimized by measurements during the use phase. This makes it possible to continuously monitor, verify and, if necessary, adapt the safety and economic efficiency of designs over their service life.
The methods of system identification in research and teaching are used here on the basis of innovative numerics, sensor technology, digital technology and computer technology.
