Abstract

<p>The non-engineered housings of RC frame with masonry wall structure have serious problems. One of them is that they must collapse due to destructive earthquakes which will take place in future. We tried to make clear of their dynamic parameter properties, related to the seismic design and the earthquake damage. First, the fundamental natural frequency/period was obtained based on the microtremor observation results and the damping ratio on the artificial force-vibration tests. The restoring force models are assumed based on the static lateral force tests and they are introduced into the dynamic earthquake response analysis. Last the analytical results are discussed considering the earthquake damage and disaster.</p>
