Abstract
This paper introduces research into the effects of earthquakes on composite masonry and concrete buildings in China. The quasistatic test is used on a nine-storey composite masonry quarter-scale model. The structure is analysed under loads to assess structural ductility, power absorption ratio, damping, etc. Testing indicates important conclusions for architects and policy makers. Bending effects induced by earthquakes can be minimized and controlled by the design of the building's depth to width ratio. Composite masonry construction can be an appropriate technology for buildings of less than nine storeys in China's earthquake regions. Cet article presente les recherches relatives aux effets des seismes sur des batiments composites maconnerie/beton en Chine. Le test quasi statique porte sur une maquette au 1/25eme d'un immeuble composite de 9 etages. La structure est analysee lorsqu'elle est soumise a des charges afin d'evaluer la ductilite structurale, le coefficient d'absorption de puissance, l'amortissement, etc. Les essais debouchent sur des conclusions interessantes pour les architectes et les decideurs. Les effets de la flexion provoquee par les seismes peuvent etre reduits a un minimum et maitrises par le calcul du rapport profondeur-largeur d'un batiment. La construction composite en maconnerie peut etre une reponse technologique appropriee pour des batiments de moins de neuf etages dans les zones sismiques en Chine.
