Abstract:
Anchorage length and splicing length of rebar, cut-off of tensile reinforcement and the detailing of beam-to-column joints of frames based on GB 50010—2002, ACI 318-08 and EN 1992-1-1:2004 were comparatively studied. Meanwhile, the effects of the rebar strength, rebar diameter, spacing of rebars, concrete strength and thickness of concrete cover on anchorage and splicing length calculated according to the aforementioned standard were analyzed. Results show that the anchorage length of rebar calculated according to EN 1992-1-1:2004 is smaller than Chinese code and ACI code, and ACI code is the greatest. With regard to the splicing length, based on the same material factors and low overlap ratio, calculations of Chinese code and ACI code are greater than European code. For cut-off of tensile rebar, the development length of rebar based on European code is greater than Chinese code and ACI code as a result of considering the increase of tensile stresses due to diagonal cracks into account.
