The wooden frames of the remains of traditional Chinese architecture w
ere built up using plug-slot type of beam-to-column connections withou
t using any metal nails or bolts. One type of these connections common
ly found in primary frames has been studied. Three different types of
artificially degraded connections that imitate those deteriorated cond
itions naturally were investigated experimentally, The behaviour of th
ese connections is found to be semirigid, They can be simulated by a t
hree-parameter connection model, The effects of semirigid connections
on frames were also studied through tests and the second-order elastic
analysis by the Newton-Raphson method, It is shown that the behaviour
of the frame is dominated by the characteristics of the connections,
The proposed numerical method can accurately predict the response of t
he partially restrained wooden frame. Copyright (C) 1996 Elsevier Scie
