The Analysis And Research Of Composite Board Under Horizontal Load In The Spatial Structure

The engineering application and mechanical analysis of concrete frames with fiber plasterboard (referred as composite board below) in our country is a new domain which has a major significance for the sustainable development in construction and building materials industry. Composite board makes up for the low strength of gypsum plank, so it is not only used in internal decoration such as ceiling suspension, or in non-structure components such as nonbearing walls, but also used as main wall.In order to make a further research of the composite board's performance in high-rise structure, according to the structure characters, the author sets up the calculating diagram in the way that depart the plasterboard and the frames consisting of concrete core and ring beam away, and join them together with isotropic chain-pole. This paper presents a method for calulating the internal force and displacement of a uniform structure(same concrete-filled styles on the vertical)and non-uniform structure(different concrete-filled styles on the vertical). Through the calculation for a typical experimental structure, the displacement curve of different concrete-filled styles under various horizontal loads can be obtained .Then the author derives the feature of displacements under normal curcumstances and demonstrates the feasibility of using non-uniform structure. The paper also makes an approximate analysis of concrete core and plasterboard'plastic properties respetively, then the failed process of the composite board can be deduced. This paper provides a more reasonable simplified calculation method for wider application.
