    Abstract: The performance of cross-laminated timber (CLT) panels in building applications have been investigated extensively. However, limited information is available regarding the performance of CLT panels for bridge applications, as well as the torsional performance of CLT panels under asymmetric loading, geometry, and boundary conditions. The objective of this study was to investigate the torsional performance of skewed CLT pedestrian interior bridge deck panels through large-scale structural testing. The panels were designed as a pedestrian bridge crossing over an atrium of The Canyons building in Portland, OR. The test panels were subjected to line and uniformly distributed loads to replicate the reactions from the adjacent panels and design loads directly applied to the panel, respectively. Two different loading configurations based on the 2014 Oregon Structural Specialty Code (OSSC) were applied with up to three different loading intensity levels. An additional loading configuration, which was beyond the scope of the OSSC, was also applied in the second series of tests to determine if panel failure could be induced. The test results demonstrated that the test panels were able to recover their original shape without suffering major damages on the panel. The measured residual deformation after the removal of the applied load was very small. The findings of this study broaden the current state of knowledge of the structural performance of a CLT bridge deck panel under asymmetric loading, and the test results can be used for future design problems.
