STRUCTURAL CHARACTERISTICS OF EXISTING HIGH-RISE RC BUILDINGS CLASSIFIED AS SEISMIC RESISTANT, SEISMIC RESPONSE CONTROL, AND SEISMIC ISOLATION STRUCTURE

Abstract

This study involved the collection and analysis of data concerning the structural characteristics of approximately 600 high-rise RC buildings in Japan constructed from 1972 to 2015. The structural characteristics were analyzed focusing on differences in seismic resistant structures, seismic response control structures, and seismic isolation structures. The construction ratio of seismic response control structures and seismic isolation structures to all high-rise RC buildings increased with time. The number of floors and spans was increased because of the strengthening of construction materials and development in the technologies concerning seismic resistant structures, seismic response control structures, and seismic isolation structures.
