摘要
钢筋混凝土叠合梁的叠合面抗剪验算是装配整体式结构设计中的重要问题,但是国内外各规范给出的计算公式却各不相同。本文重点讨论了叠合面抗剪验算时计算隔离体的选取,指出了现行国家规范公式存在的不足。文中给出了基于试件试验回归公式,并与国际标准具有相似形式的计算公式,可用于结构设计。
In the design of monolithic precast concrete structure,interface shear checking of reinforced concrete composite beams is an important issue. However,different formulas were given by several domestic and international building codes. In this paper,selection of isolation- unit in interface shear checking was discussed as a focus. Some deficiencies in current national code formula were pointed out. Moreover,a design formula is put forward based on regression equation of experimental investigation,which is considered as similar form of formula as the international codes and can be applied in structural design.
