Deformation and Synergetic Effecting of Material Layers for Concrete Roof Engineering
The roof material will deform under the action of various influencing factors,and the waterproof layer will be subject to the synergistic effect,which will affect the waterproof effectiveness.The deformation of material layer is mainly affected by temperature,humidity and load,which is suitable to be calculated by experiment,analytical formula or finite element method.The relative deformation between materials can be combined based on the structure and material deformation.The synergism of material deformation includes deformation amount and deformation rate,which is suitable for the calculation of uncertain parameters.The mechanism and calculation method of material layer deformation and its synergism are the basis for the research of waterproof effectiveness.
