Abstract
The article provides answers to questions on the instructions of SP 63.13330.2018 on the design of concrete and reinforced concrete structures, most often received by the developers of the set of rules from its users. The range of issues related to the instructions of the set of rules for calculating the strength of normal and inclined sections of reinforced concrete structures and for calculating their crack resistance is considered. Answers to the questions of users of the set of rules are presented, explanations of its individual instructions are given, and for some instructions, recommendations are given for their implementation.
Keywords
concrete,
reinforced concrete,
reinforcement,
strength calculation,
bending moment,
transverse force,
longitudinal force
Supporting agencies: Some of the issues were considered at the expense of funding allocated by the FAO “FCA”.
