Dynamic and static analysis of structure and foundations

Question

Accepted Answer

Dynamic and static analysis of structures and foundations is essential for ensuring their stability and safety.

Dynamic analysis involves studying the behavior of structures under dynamic loads such as earthquakes or wind.
Static analysis focuses on the response of structures to static loads like gravity or applied forces.
Both analyses help in determining the structural integrity, performance, and design optimization.
Dynamic analysis techniques include modal analysis, response spectrum analysis, and time history analysis.
Static analysis methods include finite element analysis, structural analysis software, and hand calculations.
Combining both analyses provides a comprehensive understanding of the structure's behavior and helps in making informed design decisions.

Accepted Answer

The main difference between static and dynamic analysis is TIME! If the load is applied so slowly, that inertia effects won't play a role, all you need is static analysis. Dynamic analysis handles impacts and other “fast” happening situations, but also vibrations (which happen in time)
