GaLa Reinforcement is a free program (part of Dr. Ilia Alashki Ph.D. thesis) for advanced analysis and design of reinforced concrete elements (columns, beams, shear walls) subjected to axial forces and axial or biaxial (Mx and My) bending moments.The program calculates the necessary areas of the reinforcing bars (automatic optimization is available), the R/C cross-sections strains, stresses, curvatures and stiffnesses (with accounting the creep and the nonlinear creep), the cracks widths and spaces, checks the R/C cross-sections reliability, generates interaction failure surfaces.

Concrete Design Codes:

Type of Loads:

N, Mx - axial force + axial bending moment.

N, Mx, My - axial force + biaxial bending moment.

Cross-section Types:

Standard cross-section types

User defined cross-section type

Analysis Types:

1. Design Section: The program calculates the necessary area of reinforcing bars. (Examples 1, 2)
2. Check Section: The program checks the capacity of R/C cross-sections with predefined reinforcement.
3. Failure Surface: The program calculates and draws interaction failure surfaces of R/C cross-sections with predefined reinforcement. (examples 3, 4)
4. Stress-strain: The program calculates the strains and stresses of R/C cross-sections with predefined reinforcement.
5. 1/r - EI: The program calculates the curvatures and stiffnesses of R/C cross-sections with predefined reinforcement.
6. 1/r - EI chart: The program calculates and draws the curvature and stiffness charts of R/C cross-sections with predefined reinforcement. (Example 5)
7. Crack widths: The program calculates the cracks widths and spaces between the cracks of R/C cross-sections with predefined.

Examples:

Example 1: Design Section (Applied loads: N, Mx, My)

Example 2: Mx-N Interaction Failure Surface

Example 3: Mx-My Interaction Failure Surface
