Cooperative Performance of Sandwich Insulation Walls With Expanded Polystyrene Under Static Loads
Sandwich insulation walls can bear loadings and insulate thermal which are fit for cold and freezing areas. In this paper, small-sized concrete hollow blocks are selected as interior and exterior wall; expanded polystyrene (EPS) plates are selected as thermal insulation layer which are put between inner and outer layers. Effects of several factors on cooperative performance of interior and exterior wall under static loads were analyzed by numerical simulation. These factors include the type of connection steel, the vertical load and the property of interface between EPS and concrete blocks. The results show that among the connection steel of ‘Z’ shape, ring shape and tie netting, the last is the best. Displacement difference between interior and exterior walls increases with increasing vertical load. And if the interface friction between EPS block and concrete blocks is considered, displacement and displacement difference of sandwich walls all increase. These results agree with similar tests.
