Abstract
The Chi-Chi earthquake of 1999 struck many traditional timber structures, which
resulted in irreversible disaster to cultural heritage in Taiwan. Since then, many
efforts had been devoted to investigation on the structural behaviour of these
historic buildings. This paper addresses the efforts being invested to studies on
the issue aforementioned. Timber is one of the materials that frequently used in
historic buildings in Taiwan. A five-year research project was initiated to explore
the structural behaviour of traditional Chuan-Dou timber structures. The project
involved explorations on the mechanical behaviour of structural components in
the beginning, followed by studies on behaviour of the entire structure, which we
call the bottom-up approach.
In the first stage, an extensive field survey was conducted from central to
southern Taiwan to collect the necessary information for experimental designs
and tectonic analyses of traditional Chuan-Dou timber structures. Later, studies
concerning the mechanical performances of their timber connections and timber
shear walls were carried out by experiments and analytical approaches. Tests
were also conducted on traditional mud shear walls to obtain the strength within
various types of bamboo lath of these mud shear walls. After mechanical
performance of these structural components were obtained, full-scale
experiments on traditional timber frames were then carried out to study the
global behaviour in contrast to those of structural components. The five-year
project in Taiwan demonstrates that the structural behaviour of these traditional
timber structures can be studied by a bottom-up process and good results
obtained.
