摘　　要：缀板梁体系 ,是基于准则法结构优化理论的创新结构形式 ,从准则法结构优化理论出发 ,提出了弯剪构件结构体系的优化准则和优化手段 ,提出的优化准则是每根梁上的多个弯矩峰值相等 ,优化手段是设置附加剪弯杆 (缀板 )并以其位置和刚度为主要设计变量进行优化。The latticed beam system is a new\|invented structure type based on structural theory of optimality criteria method. From structural theory of optimality criteria method, the optimality criteria and optimizing mechanism of structural system of shear\|bending bars are presented in this paper.The optimality criteria presented is equalizing all extrema of bending moment at a beam. Optimizing mechanism is seting up extra shear\|bending bars (latticed plates) and adjusting their positions and stiffness to optimization.
