DEVELOPMENT OF A SIMPLIFIED AND PRACTICAL ANALYTICAL MODEL FOR STRUCTURAL DESIGN OF CLT BUILDINGS

Abstract

Currently, standard analytical models for designing CLT structures are very complicated. In this study, an evaluation method for the restoring force characteristics was proposed to enable structural analysis using a simplified model of elastoplastic bending spring model, which is more practical in structural design. In addition, the validity of the proposed model was examined by comparing its results with those of conventional models and experiments on CLT walls. As a result, although some problems remain in the stiffness evaluation, the lateral strength capacity can be evaluated accurately, and the possibility of applying the model to practical structural design was demonstrated.
