| Abstract | Collapse or severe damage has been observed in many RC residential buildings with soft-first story at the previous earthquake disasters. This paper proposes a new technique for structural control of RC buildings with soft-first story by using High Performance Fiber Reinforced Cementitious Composite (HPFRCC) devices, which are placed beside the existing columns in the first story. Since the HPFRCC exhibits multiple cracking and strain-hardening characteristics in the uni-axial tensile stress, the HPFRCC device shows a very good ductile structural manner in conjunction with a high resistance capacity against the axial force. The advantage of the HPFRCC devices is selective structural performance by varying the configuration, bar arrangements and type of materials used. Also, axial force acting in the existing columns due to overturning moment can be reduced since the HPFRCC devices can resist to the axial force. As the result of analysis, the seismic response of the buildings was successfully controlled to meet high level of structural performance requirements by using HPFRCC devices. |
