| Research Abstract |
A high performance RC building structural system has been constructed in order to maintain structural functions based on experiments and numerical analyses. To conclude the works in the project, a real scale four story post-tensioned precast concrete building was tested on the E-defense shaking table as a part of the collaborative US-Japan project. The structure shows excellent performance for various intensity of simulated earthquakes. Interstory drifts were minimal during the shaking and residual displacements and cracks were almost zero to achieve a damage control system. Unfortunately, the stiffness decreased dramatically for a Level 2 earthquake since bases of columns and walls had spalling of cover concrete. However, it was confirmed that the stiffness degradation could have been prevented by supplying fiber reinforced concrete at bases of columns and walls.
