FRP Column Confinement Analysis
FRP Column Confinement Analysis
FRP Column Confinement Analysis is a comprehensive analysis and design software for reinforced concrete columns confined with FRP wraps. It is designed and tested for rectangular, circular, and elliptical column sections. It enables the generation of limit and design interaction diagram for short columns, considering biaxial bending plus axial compression-tension forces in accordance with ACI 440.2R-17 and ACI 318-19. The user also has the option to analyze and design slender columns by including the slenderness effect in accordance with either the ACI moment magnifier method or an Advanced Method formulated by the developers of the software. The software operates in dual units SI and US customary units with full capability of switching back and forth between them. It is also made powerful by providing special utility tools capable of designing for the required longitudinal steel ratio or confinement FRP ratio. Furthermore, the software is supported by a professional design report consisting of input parameters and output results.
The software inputs are divided into material and geometrical properties, where every category covers the different properties for concrete, steel and FRP. For the interaction diagrams, the user can select to plot limit, design, unconfined or confined interaction diagrams at any desired slope angle of biaxial moment ratio. Moreover, the user can plot demand values to check whether they fall inside or outside the interaction diagrams. The software is further equipped with full consideration of slenderness effects in both directions with sway or no sway mode options and combinations thereof. The final product is very versatile in offering a wide range of load combinations, slenderness effects and analysis/design interaction diagrams.

Dual Units
Dual units capabilities (US Customary units and SI units).
Complete Material Definition
Well-defined material parameters for concrete, steel and FRP. The software supports a manufacturer library for FRP material properties.
Complete Geometry Definition
A complete definition for the geometry of the cross section (Rectangular, Circular and Elliptical), maximum aggregate size, longitudinal and transverse steel reinforcements, and confinement FRP wraps.
Errors and Warnings
The software is equipped with error and warning pop-up messages to help guide the user towards following ACI requirements and provisions.
Slenderness Effect
The software can take into account the slenderness effect in both directions with sway or no sway mode options and combinations thereof. It also offers a wide range of load combinations. To facilitate the use of the slenderness form, a detailed guidelines is provided.
Dual Methods for Slenderness Analysis
The slenderness analysis can be carried out in accordance with either the ACI moment magnifier method or an advanced method formulated by the developers of the software. This method is especially more accurate in the case of sway frames.
Complete Frame Analysis
To make the software more powerful, it is equipped with the complete capability to perform first order frame analysis overcoming the need to use another software to obtain first order moments. It can handle up to 7 spans in each direction. It can also account for distributed loads in addition to the concentrated loads.
Biaxial Bending Moment
The software takes into account the biaxial moment effect on the section from the x-direction and y-direction. The user can choose the slope angle of biaxial moment ratio corresponding to the desired interaction diagram.
Fully Developed Interaction Diagram
A complete interaction diagram between the biaxial resultant moment and axial forces including the tension zone.
Limit State Interaction Diagram
The software generates the limit state interaction diagram of the cross-section without accounting for the strength reduction factor. It can be generated for the unconfined reinforced concrete section as well as the FRP confined section.
Design State Interaction Diagram
The software generates the design state interaction diagram of the unconfined and FRP confined cross-sections taking into account the strength reduction factor and all safety provisions in accordance with ACI 440.2R-17 and ACI 318-19.
Design for Optimum Steel Ratio
For a constant FRP ratio, the software generates multiple design interaction diagrams for different steel ratios. This extremely facilitates the process of choosing the optimum steel ratio necessary to meet all demand values.

Tabulated Data
Tabulated data of the interaction curves can be accessed for further investigations.
Demand Values
Up to 10 different demand values can be plotted to check the adequacy of the cross-section for them. The color of the demand value plot point aids in determining whether the cross-section is adequate or not.
Magnified Load
The magnified load due to the slenderness effect is reflected on the interaction diagram as a design loading point to check if it is below or above the cross-section’s capacity.
