Abstract

Full-scale temperature tests were conducted on inner and outer wythes with single-piece truss connectors, both with and without openings, connected to sandwich insulation wall panels. The purpose of the study was to investigate the deformation and stress performance of these panels under temperature differentials between the inner and outer wythes. The test results showed that throughout the temperature variation process, the concrete temperature of the inner wythe remained stable. The sandwich insulation layer exhibited good thermal insulation performance, and the heat transfer through the connectors had minimal impact on the temperature changes of the inner wythe. During the cooling process, no cracks were observed on the surface of the specimens. During the heating process, the crack widths of both specimens remained below 0.2mm. The overall effect of temperature on the outer wythe, constrained by the inner wythe, was relatively small. Under the influence of temperature difference, the specimens exhibited some warping deformation. However, the deformation values did not exceed the allowable limits for the facade panels.
