Dynamic modeling of a PCaPC seven-story building is examined with comparing observed earthquake response characteristics. Some points of structural modeling, such as the evaluation of live load, stiffness of concrete, and detailed modeling of frames and slabs, are proved to be effective in natural frequency of the building. Dynamic soil-structure interaction effect is also verified with modeling of soil, pile and embedded foundation. It is important to accumulate such modeling with observed data for the evaluation and improvement of structural modeling methods.
