Analysis Verifier
RKALC Analysis Verifier brings together a suite of focused structural-analysis tools for concept design, independent checking and interpretation of results from larger analysis packages. Each application is intended to keep the governing assumptions and structural behaviour visible, allowing engineers to test schemes quickly, benchmark detailed models and make informed engineering decisions.

Continuous Beams
The Continuous Beam application provides rapid elastic analysis of multi-span beams and one-way slab strips. Engineers can define spans, support conditions and loading, then review reactions, shear forces, bending moments and deflections through a clear graphical workflow.
The tool is suited to preliminary sizing, scheme development and independent verification of results from detailed structural-analysis software. By presenting the fundamental structural response directly, it helps engineers assess load paths, understand behaviour and confirm that more sophisticated models are producing results of the expected order and distribution.
WindKALC
WindKALC provides wind-action calculations in accordance with AS/NZS 1170.2:2021, including the assessment of directional wind response and the dynamic behaviour of wind-sensitive buildings. The application brings the principal wind parameters, response calculations and loading distributions into a transparent workflow that can be reviewed and checked by the engineer.
Directional loading tables can be generated for use in structural-analysis models, supporting both preliminary design and independent verification of applied wind actions. The tool is particularly useful during scheme development, when engineers need a rapid understanding of along-wind and crosswind response before detailed modelling or specialist wind studies are available.
Static Base Shear
The Static Base Shear application calculates equivalent static earthquake actions in accordance with AS 1170.4. It provides a rapid means of estimating seismic demand and reviewing the distribution of horizontal earthquake forces through the height of a building.
The application is intended for preliminary design and independent benchmarking of more detailed response-spectrum, time-history or other seismic-analysis models. Clear tabulated and graphical outputs help engineers compare overall base shear, force distribution and the adopted building period against the results of their primary analysis software.
Coupled Shear Wall
The Coupled Shear Wall calculator provides a transparent analytical approach to coupled-wall behaviour using classical closed-form theory. It allows engineers to examine the interaction between wall piers and coupling beams, including the influence of relative stiffness on the distribution of forces through the height of the system.
By varying wall and coupling-beam properties, engineers can test structural schemes, assess the expected level and distribution of coupling action, and compare the results with detailed finite-element models. The application is particularly valuable during concept design, where an early understanding of stiffness, load sharing and coupling behaviour can guide modelling assumptions before detailed analysis is undertaken.
Period Calculator
The Period Calculator estimates the natural periods of idealised building systems using free-vibration theory. It provides a direct relationship between structural mass, lateral stiffness and dynamic response, giving engineers a transparent basis for understanding the periods obtained from more detailed analysis models.
The application is suited to preliminary wind and earthquake studies, sensitivity checks and independent verification of modal-analysis results during the development of a structural scheme.
TribKALC
TribKALC is a graphical tributary-area and gravity-load take-down tool developed for rapid assessment of floor systems. Users can import a PDF floor plan, calibrate the drawing scale, trace slab edges, columns, walls and cores, and generate tributary areas and column loads directly from the defined geometry.
The visual workflow supports concept design, load verification and rapid development of structural schemes without relying on manually constructed spreadsheets. Results can be reviewed graphically and carried forward into subsequent analysis and design workflows, providing a clear connection between the floor plan, tributary geometry and calculated loads.
CentresKALC
CentresKALC supports the conceptual development and independent verification of building lateral systems. The application calculates centres of mass and rigidity and distributes direct and torsional shear to walls and cores based on the defined floor geometry and stiffness characteristics.
Geometry can be drafted directly or traced over an imported PDF floor plan, allowing engineers to assess eccentricity, torsional response and relative wall demand at scheme stage. The graphical workflow provides a practical means of testing alternative lateral-system layouts and independently checking the load distribution obtained from detailed structural-analysis models.
PileGroupKALC
PileGroupKALC is a graphical analysis tool for estimating pile reactions arising from axial load, biaxial moment, torsion and lateral shear. Engineers can define pile, pile-cap, wall and core geometry and review how the applied actions are distributed through the pile group.
The application supports direct drafting as well as PDF-overlay workflows, making it well suited to preliminary foundation design, scheme comparison and independent verification of pile reactions. Its visual approach allows the engineer to review the geometry and calculated response together before progressing to detailed foundation analysis and design.
