This mode enables to select reinforcement and check the specified reinforcement in the elements of reinforced concrete structures for the ultimate and serviceability limit states in accordance with the requirements of SNiP 2.03.01-84* “Concrete and Reinforced Concrete Structures ”, KMK 2.03.01-96, SNiP 52-01-2003 (SP 52-101-2003) or SP 63.13330.
The analysis is performed for reinforced concrete structures made from heavy-weight, fine-grained and lightweight concrete with the reinforcement steel or the reinforcing wire.
The library of procedures of selecting the reinforcement contains the following modules:
The following initial data has to be specified for the work of the postprocessor:
The check and selection of reinforcement in bar elements is performed in accordance with the method given in the selected code. Since the procedure for checking the reinforcement in the elements of shells, plates, etc., is not given in the codes (except for SP 63.13330), the method proposed by N.I. Karpenko [3] is used in SCAD. Recommendations of SP 63.13330 are also based on this method. The main guidelines of this method are given in the Basic Principles of the Selection of Reinforcement in the Finite Elements of a Slab and Shell section. It should be noted that they correspond to the general guidelines for calculating planar structures given in Sec. 1.38 of SNiP 2.03.01-84*.
Moreover, unlike SP 52-101-03 (more specifically, the Guide to this SP) the condition of formation of oblique cracks is not considered in SP 63.13330. However, the software performs this check if there is a requirement of the absence of cracks. The analysis is implemented in accordance with the recommendations of Sec. 4.28 of the Guide to SP 52-101-03.
