摘　　要：基于 1 0根两阶段均布荷载作用下钢纤维混凝土迭合梁的试验研究 ,对比普通混凝土迭合梁的研究成果 ,建立了均布荷载作用下无腹筋和有腹筋钢纤维混凝土迭合梁斜截面承载力计算公式。计算公式与《混凝土结构设计规范》 (GBJ1 0 -89)和《钢纤维混凝土结构设计与施工规程》 (CECS3 8:92 )相协调 ,便于设计应用。Based on experimental study of SFRC composite beams with two stage uniformly distributed load and results of common reinforced concrete (RC) composite beams, formulae for calculating the ultimate bearing capacity for inclined section of SFRC composite beams without or with stirrups under two stage uniformly distributed loading are proposed The formulae are in tune with the corresponding “Design Specifications for Reinforced Concrete Structures”( GBJ10 89) and “Regulations of Structural Design and Construction of Steel Fiber Reinforced Concrete”(CECS38: 92) and are convenient to practice
