RcSections

is a powerful 32-bit Windows program designed specifically for structural engineers to perform axial-flexural analysis and design of concrete sections (beams, columns or walls) according to ACI 318-05/02 and ACI 318-99. It analyzes the uniaxial- or biaxial-bending capacity of multiple sections of various regular shapes (rectangular, round, Tee, I, L) and generic shapes (with openings) simultaneously in a fast and user-friendly manner. Multiple load sets may be input and checked against section capacities. It features tabulated strain-P-M at every user defined neutral axis step, 2D P-Mx and P-My interaction diagrams, and incredible 3D P-Mx-My interaction surface built upon OpenGL(R)!

Key Features

• Codes: ACI 318-05, -02 and -99
• Unit: English, Metric or Mixed
• Section Shapes: Unlimited number of rectangular, tee, circular, I, inverse L and generic (with up to 3 openings) sections. Ability to convert various regular sections to generic sections. Ability to parametrically generate multiple rectangular or circular sections with different sizes and reinforcement configurations. Great tool for shortening the trial-and-error design process
• Loads: Unlimited number of load sets (Pu, Mux, Muy). Adequacy of each section to carry the loads is computed in terms of simple capacity ratio
• Moment releases on frame element

• Solver: Unique, exact and blazingly fast solution algorithms that can accurately solve hundreds even thousands of sections uniaxially or biaxially simultaneously in seconds. Solution options include strength reduction factor, tied or spiral confinement, variable number of neutral axis steps, variable biaxial angle steps, variable axial steps for display and inclusion or exclusion of displaced concrete
• Result Data: Very detailed result data tabulated in spreadsheets. P-M result includes neutral axis depth, eccentricity, maximum tensile strain and strength reduction factor, as well as axial capacity P and moment capacity M
• Diagrams: 2D P-Mx, P-My and Mx-My interaction diagram and 3D P-Mx-My interaction surface or wire-frame. Key points shown automatically on the interaction diagrams. Input loads shown with different colors on the 2D/3D diagrams or surface denoting the adequacy of the section for each load
• Printing: Automatic printing of very impressive interaction diagrams for multiple sections. If you happen to have PDF making software, you will be able to create your very own design handbook similar to CRSI Handbook! Here is an example

User Interface Features

• Easy input through menus, toolbars, dialog boxes and spreadsheet
• Multiple images such as section geometry, P-M interaction diagrams may be captured automatically. Captured images may be saved or printed
• Results detailed in the spreadsheets. May be copied and pasted to your favorite spreadsheet program such as EXCEL (So you may even construct interaction diagrams of your own style!)
• Other nice features such as undo/redo, multiple document interface, multiple views, real-time zooming, panning and rotation, and customizable report in ASCII text file format or HTML file format

System Requirements

• Computer CPU: Intel Pentium based; 450 MHz or faster is recommended
• Memory (RAM): Minimum 64 MB; 128 MB or more is recommended
• Operating System: Windows 95 (OSR2) or later; Windows NT 4.0 or later, Windows 2000, XP or Vista is recommended
• Video Card: Minimum 4MB, OpenGL(R) hardware acceleration essential. Most of the graphics cards sold these days support OpenGL(R) acceleration

Program Capacities

Real3D-Analysis uses dynamic memory allocation technique which does not require preset program capacity. However, in order to make the program more affordable and to meet different needs, we offer Real3D-Analysis in different versions as indicated in the following table
