| Abstract: | The free vibration characteristic of steel-concrete composite ribbed shell is taken into account the influence of many kinds of factors such as the rise-span ratio,the ratio of length span and short span,the size of composite rib,the condition of supports and so on,by using the finite element method.The traits of modes are also analyzed,and the weaker stiffness parts of the structure are found which provide reference for the aseismic analysis of the structure. |
