From shear walls to tilt-up, precast, and ICF walls, engineers worldwide use spWall (formerly pcaWall, PCA-Tilt, TILT) to optimize complicated wall design, reinforcing, and deflections.

spWall, formerly pcaWall/PCA-Tilt/TILT, is for design and analysis of reinforced concrete walls, tilt-up walls, and precast architectural and load-bearing panels. It uses an advanced graphical interface that enables the user to easily generate complex wall models. The geometry of the wall (including any number of openings and stiffeners), the material properties, the loads (point, area, and line), and the support conditions are assigned graphically using the mouse. Also, springs (translational and rotational) can be graphically assigned at any node.

The program is based on the finite element method and can take into account second-order effects. The wall may include any number of openings and stiffeners. The amount of steel required for flexure is computed based on the selected design standard, and the user can specify one or two layers of reinforcement. The program also calculates the amount of steel required for shear and torsion in the stiffeners but does not calculate shear reinforcement in the wall elements.

spColumn complements spWall by generating axial/flexure (P-M) diagrams suitable for shear wall design.
