Abstract:
Which ACI documents include information regarding the timing for removing forms? Section 25.4.2.3 of ACI 318-191 refers to Table 25.4.2.3 for calculation of development length for deformed bars. Is the indicated clear spacing in Table 25.4.2.3 measured between the lapped bars or between adjacent splices? If we allow noncontact splices and require that they meet the requirements of Section 25.5.1.3, with center-to-center spacing of the lapped bars being no more than lap-length/5 or 6 in., is the lap length the same as it would be for a contact splice?
