Abstract:
A National Project lasting five years has been promoted by the Ministry of Construction of Japan since 1988 to develop super high-rise reinforced concrete buildings in seismic zones. The strength of concrete and reinforcing steel bars ranges from 30 to 120 MPa (4.3 to 17.4 ksi) and from 400 to 1200 MPa (58 to 174 ksi), respectively. The following is investigated in the Project: 1) production, quality control, and placement of high-strength concrete; 2) production of high-strength steel bars; 3) mechanical properties of high-strength concrete and steel bars; 4) behavior of members and subassemblages; and 5) structural design methodology.
