Dynamic Soil-Structure Interaction

Deformation of Structures at the time of an Earthquke

KKE provide various analysis consulting services in the building and civil engineering field. We analyze vibration problem of a structure, various ground problems, and soil-structure dynamic interaction. For instance, utilizing our extensive experience and unique knowhow that we accumulated over the years, we evaluate the safety of the important structures such as a high-rise building or nuclear power plant at the time of an earthquake occurrence. Using a probabilistic method, we evaluate the reliability of a structure. Also, we have developed various unique analysis programs in order to satisfy our customers' requests. For various structures and distinct problems listed below, KKE offers optimum analysis methods and models.
