1引言厚板转换具有施工方便、布置灵活等特点,但其准确的受力分析较难实现。有些设计人员为了确保安全,将转换板设计得很厚,从而使得转换处上下刚度突图1有限元计算模型变。这样容易造成建筑物在地震作用下产生应力集中,形成受力的簿弱部位。如图1所示的转换层,如果按普通梁式 1 Introduction Thick plate conversion has the advantages of convenient construction and flexible layout, but its accurate analysis of force is difficult to achieve. Some designers in order to ensure safety, the conversion plate is designed to be very thick, so that the transition stiffness at the sudden change Figure 1 finite element model changes. This easily lead to buildings under stress caused by the earthquake concentration, the formation of the weak parts of the book stress. As shown in Figure 1 conversion layer, if by ordinary beam
