Reinforced concrete (RC) structures

12 modules
Properties of Concrete
The module provides reference materials about normative and design strength of concrete for ultimate and serviceability limit states according to SNIP 2.03.01-84* Concrete and Reinforced Concrete Structures.

Table of Reinforcement
The module provides reference materials about design area and theoretical mass per running metre of reinforcement depending on number and diameter of rebars according to SNIP 2.03.01-84*. The module also provides several additional options, such as option to find out whether number and diameters of rebars correspond to the specified area, etc.

Anchorage of Reinforcement by DSTU 3760-98
The module enables you to determine anchorage of rebars according to DSTU 3760-07. Length of anchorage may be calculated for single and for double rebars. The value of concrete cover for corner rebar is selected as the smaller one from the following values: vertical and horizontal. Calculation is made by method of successive approximation based on spacing and diameter of secondary (distribution) reinforcement.

Sections of Reinforced Concrete (RC) Elements
The module enables you to analyse reinforced concrete sections by ultimate (ULS) and serviceability limit states (SLS). The following building codes are supported: SNIP 2.03.01-84*, SNIP 52-01-2003, Eurocode 2, DSTU 3760-98, TSN 102-00*, DBN V.2.6-98:2009. Types of the sections that may be analysed: rectangular bar, T-section, I-section, angle, cross, ring, circle and box sections. Calculation is provided for the following stress states: axial compression, bending, plane eccentric compression-tension, oblique bending and general case for the set of forces N, Mx, My, Mz, Qx, Qy.

Reinforced Concrete (RC) Shell / Wall-beam / Slab
Three modules that enable you to analyse reinforcement in plate RC elements by ultimate (ULS) and serviceability limit states (SLS). The following building codes are supported: SNIP 2.03.01-84*, SNIP 52-01-2003, Eurocode 2, DSTU 3760-98, TSN 102-00*.

Principal and Equivalent Stresses
The module enables you to calculate principal and equivalent stresses by specified values of stress tensor. Principal, ultimate and equivalent stresses are calculated by appropriate strength criteria (Geniev, Karpenko, Pisarenko, Yashin, etc.) for the specified class of concrete. Moreover, values of principal strain, slope angles of principal stresses to the current axes, slope angle between plane of crack and the X-axis are also calculated. Strength zone is generated by obtained results. When you carry out strength analysis, it is possible to obtain ultimate allowed stresses by two principal planes, ultimate normal and shear stresses by octahedral planes, reserve factor for strength by SLS and Lode-Nadai coefficient.

Strengthening with Composite Materials
The module enables you to check rectangular, T-sections and I-sections of RC elements strengthened with FRP (fiber-reinforced polymer) materials. The check is made by ultimate limit states (ULS) and serviceability limit states (SLS). The program realizes regulations mentioned in Manual on Strengthening of RC Structures with Composite Materials and SP 52-101-2003.

Strength of RC Butt Joint in Shear
The module enables you to check strength of reinforced concrete (RC) butt joint in shear. Eurocode 2 and DSTU B V.2.6-156:2010 are supported.

Concrete Sections with Fiber-Reinforced Polymer (FRP) Bars
Concrete section may be reinforced with nonmetallic composite reinforcement and with several types of reinforcement, including steel reinforcement. Calculation is made by theory of ultimate states and by deformation model of reinforced concrete according to draft project of SP Structures of Concrete with Composite Nonmetallic Reinforcement.

Concrete Pipe Sections
The module for strength analysis of pipe sections by deformation model according to SP 63.13330.2012, SP 16.13330.2011 and draft project of SP Structures of Concrete with Composite Nonmetallic Reinforcement.
