Dynamic properties of traditional wooden frames filled with cavity walls
Due to their light weight,low cost,and high capacity against environmental effects,rowlock cavity walls made in thin black bricks had been widely used as envelopes in traditional buildings in south China.The main frames of this kind of buildings are usually made in timber.The cavity walls are relatively weak in the out-of-plane direction,and most of the vertical loads are sustained by the wooden frames.In this paper,we clarify that these walls also contribute to stiffness of the building,especially in the horizontal direction.This traditional structural system was invented more than five hundreds ago,and had been playing a key role as residential architectures in south China until recently.However,there have been only little existing studies on their structural performance,while none of these studies investigated their dynamic properties.Due to aging of materials,many of these traditional wooden frames filled with cavity walls are in dangerous states,and many of them have been destroyed.To protect the existing buildings from further damage,it is urgent to properly evaluate their structural performance,before and after reinforcement.This paper is a preliminary study on the traditional buildings made of wooden frame and rowlock cavity black-brick walls.We present the experimental results of microtremor measurements of two typical buildings,in order to elucidate their dynamics properties.
