ABSTRACT

Currently, there is a scarcity of studies in the literature that offer a comprehensive insight into the non-seismic design of post-tensioned timber structures. This research focused on investigating the structural non-seismic design of post-tensioned cross-laminated timber (CLT) shear walls using the Winkler Spring Analogy (WSA) method and the Material Based Model (MBM). The study aimed to explore the impact of various factors, such as placement, number, material, and post-tension forces, on the structural behavior and fabrication of the wall. Key findings of the study included: (1) challenges in calibrating and verifying numerical models due to limited experimental data; (2) the significant influence of CLT's orthotropy and fabrication defects on wall deformation, particularly at the bottom of the wall; (3) the utility of WSA in pre-designing structures and validating numerical models; and (4) the effectiveness of post-tensioning configuration when including at least two bars located at opposite ends of the cross-section. This research is expected to enhance awareness and understanding of post-tensioned CLT wall structures and encourage full-scale load testing.
