| 摘要： | The theme of this issue of the PCI Journal is "Slabs, Panels, and Hollow-core." Numerous research and development projects have investigated various aspects of these three component types, and this Research Corner focuses on precast concrete insulated wall panels, which are sometimes called sandwich panels. A precast insulated wall panel has rigid insulation sandwiched between inner and outer wythes of concrete. The main purpose of the insulation is to reduce heat (in other words, energy) loss through the panel, but the insulation also provides sound attenuation and impact energy absorption. Connections between the individual concrete wythes are necessary to tie the panel together. Connections may comprise solid zones of concrete or distributed or individual ties fabricated from metal, rigid polymer composite, or carbon-fiber materials. The greatest degree of composite behavior is achieved by using solid zones of concrete to connect the wythes, but this results in the poorest thermal performance. |
