| Abstract: | Concrete (PC/RC) beams with large openings are used in architectural structures, through which all kinds of accessory facilities are installed. They make it possible to lower the height of architectural structure and to increase the architectural space, so as to achieve good economic and social benefits. The paper discusses the dynamic characteristics of concrete (RC/PC)frame of beams with large openings, and analyses earthquake responses of the reinforced concrete frame with beams having large openings by emulated dynamic tests on computer.The El Centro seismic wave is used and a three floor frame structure is discussed with eight cases. The conclusions from this paper can be used as references for dynamic designing of the reinforced concrete frame with large openings in the beams. |
