- Synopsis:
- A structural system using reinforced concrete core wall makes architectural free planning possible since the core wall can bear most of seismic force and relieve the load of columns. In this study, lateral loading tests on the reinforced concrete shear wall with 120N/mm2 compressive strength concrete and uni-axial compression tests on the model extracted from the shear wall have been conducted. The test results reveal that its structural performance is greatly affected by axial compression behavior of the compression zone in the shear wall. Scale effect and lateral confinement effect should be considered appropriately in applying this structural system.
