摘要
屋面材料在各类影响因素作用下产生变形,防水层会受协同作用,进而影响防水有效性.材料层变形量主要受温度、湿度、荷载的影响,适合采用试验、解析式或有限元计算得到;材料间相对变形可基于构造、材料变形量进行组合;材料变形的协同作用包含变形量和变形率,适合引入不确定参数计算.材料层变形及其协同作用的机理、计算方法是开展防水有效性研究的基础.
Abstract
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.
