一、单向板楼盖ACI规范中关于单向板(l_2/l_1≥2) 楼盖的计算方法与我国习用的方法相似,但弯矩系数的取值稍有不同,跨度的计算亦有差别。ACI规范规定,当满足下列条件时,可采用近似的弯矩值和剪力值,以设计单向板楼盖中的单向板和连续梁,否则须按弹性理论并考虑最不利荷载位置进行计算(ACI8.3.3条):
1. The method for calculating the floor of a one-way slab (L_2/l_1≥2) in the ACI specification of one-way floor slab is similar to the method used in China, but the value of the moment moment is slightly different, and the calculation of the span is also different. . The ACI specification states that when the following conditions are met, approximate bending moment and shear values can be used to design the one-way slab and continuous beam in one-way floor slabs. Otherwise, the elasticity theory must be considered and the most unfavorable load location should be considered. Calculation (ACI 8.3.3):
