STRUCTURAL PERFORMANCE EVALUATION OF COLUMN BASE IN CLT ROCKING WALL-COLUMN WITH PRESTRESS INTRODUCED

In the case of a change in the amount of prestress and the cross-section area of the PC bar

Abstract

This study conducted a static horizontal loading experiment on CLT rocking wall columns by introducing pre-stress. We understood the mechanical behavior in the case of changing the pre-stress amount and the PC bar’s cross-section.

We proposed a method for evaluating the relationship between the bending moment and the rotation angle of column base. The characteristics of the evaluation method are (i) Analyzed stress distribution cases at column bases and (ii) The uplifting of the column base was modelled using a spring model. The evaluation results could roughly reproduce the experimental values, although there were some improvements.
