Abstract
Dou-gong connection (complex bracket) is one of the typical wood-wood connections commonly used in traditional Chinese timber structures. The hysteretic performance of dou-gong connections is pertinent to the seismic performance of the traditional timber structures. Compared with experimental research, numerical simulation is more cost effective and not limited experimental techniques and thus is more versatile in study of hysteretic performance of dou-gong connections. In this paper, a three-dimensional finite element method(FEM) based analysis on hysteretic performance of single and double dou-gong connections was presented considering three dimensional elastic-plastic and damage constitutive model of wood. The results showed that the model prediction of the initial stiffness and lateral resistance of the connections agreed well with the test results in literature.
