Full-Scale Composite Sandwich Walls: Theory and Behavior

钢筋混凝土复合夹层墙系统正变得非常受欢迎，因为它结合了横向、重力和平面内载荷的许多好处，以及隔热夹层结构的热效益。这些墙通常由两层（wythes）加固（或预应力）混凝土夹层围绕中间层隔热层组成，为热效率提供足够的r级。为了保持绝缘额定值并防止热短路，需要使用非金属扎带连接器，如纤维复合扎带。本研究的目的是确定复合作用的量，导致夹心系统受到横向和轴承载荷。这一目标要求开发相应的分析工具，并进行实验测试以验证理论。将进行大约32英尺长的墙壁测试，以承受横向或承重载荷。行业协作和合作是分担成本和参与该项目的关键因素。这项研究预计将产生一个理论模型，用于分析未来的墙壁，行为特征（包括复合作用的数量），设计建议，以及纳入新设计标准的潜在条款。

Reinforced concrete composite sandwich wall systems are becoming very popular due to the many benefits of combining lateral, gravity and in-plane loads along with the thermal benefits of the insulated sandwich construction. These walls typically consist to two layers (wythes) of reinforced (or prestressed) concrete sandwich around a middle layer of insulation, providing sufficient R-rating for thermal efficiency. In order to maintain the insulated rating and to prevent a thermal short-circuit, non-metallic tie connectors, such as fiber-composite ties are required. The objective of this research is to determine the amount of composite action resulting in the sandwich system subjected to lateral and bearing loads. This objective entails the development of the commensurate analytical tools coupled with the experimental tests to verify the theory. approximately 32-ft long wall tests subjected to lateral or bearing loads will be conducted. Industry collaboration and cooperation is a key element in shared cost and participation in this project. This research is expected to result in a theoretical model for analysis os future walls, behavioral characteristics (including amount of composite action), design recommendations, and potential provisions for inclusion in new design standards.
