Abstract |
This study focuses on the experimental investigation of thermal heat bridge prevention systems in terms of the shear capacity resulting from bearing loadings supported by precast ultra-high-performance composite (UHPC) ribs with normal concrete PC cladding walls. Five specimens were tested under static loading conditions to examine both structural performance and the thermal behavior of UHPC ribs with and without shear keys. The test results showed that the specimens had excellent structural performance in terms of shear capacity, surpassing that developed by normal concrete by approximately threefold. When the experiment was conducted with various eccentric distances, the bearing load performance was the highest with the smallest eccentric distance provided. It was verified that the shear key presence contributed to enhancing the bearing load performance by about 5 %.
