A rocking spine for enhanced seismic performance of concrete buildings with infills
Abstract/Contents
- Abstract
- Reinforced concrete frames with infill panels is a commonly used building system in many moderate and high seismic regions around the world, particularly in developing countries. In some cases, the frames are designed to resist earthquake loads but the infill panels are rarely ever incorporated in the structural design. Moreover, the layout of the infill can have severe negative effects on seismic performance, which is also seldom considered. This research utilizes state-of-the-art performance-based earthquake engineering and computational modeling methods to develop a novel technique envisioned as a cost-effective approach to improving the seismic collapse safety in infill frame buildings. The proposed technique uses strong, stiff structural spines that resist earthquake effects through rocking action. The rocking spine system is applicable to both retrofit and new design; however, this work is primarily focused on the latter. The primary sources of overturning resistance are the gravity loads acting directly on the spine and the restoring forces transferred to the spine through outrigger action of adjacent structural members. These include beams framing into the spine and the infill panels constructed in the adjacent bays parallel and orthogonal to the spine. The use of rocking as the primary yielding mechanism reduces the required level of detailing that would otherwise be required in ductile concrete frames, which make the spine infill frame more practical and economical to construct. Additional material and labor cost savings can be realized for taller buildings since deep foundations are not required for the spine system. The project is executed in three phases that focused on the component, building and community scales.
