| Outline of Final Research Achievements |
This study aims to develop the mechanical model for CLT shear walls and provide useful data for the design of CLT structures. Finite Element model and dynamic model were developed for CLT shear walls and the influence of mechanical properties of joints on the seismic performance of building structures composed of CLT panels. The safety of CLT structure on the various seismic ground motions were studied by performing the time history earthquake response analysis. The failure mechanism of CLT shear walls due to the splitting of CLT at the corner of opening was also analysed by applying the average stress method in FEM analysis and it was shown that this method is appropriate to predict the crack initiation at the corner of opening. These results provide useful date for the design of large panel CLT with opening.
