Continuous and Indeterminate Beams Apparatus | FortiTestX 07

The FortiTestX 07 Continuous and Indeterminate Beams Apparatus is an electronically instrumented beam testing unit for investigating deflection, support reactions, and elastic line behaviour under statically determinate and indeterminate conditions. Five electronic load cells — three with knife-edge contacts and two with clamping fixtures — are connected to a digital force display for real-time reaction measurement. The apparatus is supplied with fifteen interchangeable beam sections across five materials and three cross-sectional thicknesses, four calibrated weight sets, and three dial gauges. Sinking support displacement is adjustable on two of the knife-edge supports for support settlement studies. Manufactured by SCIENTICO, the FortiTestX 07 is suited for advanced structural mechanics and strength of materials laboratory courses, and is available for international supply. Optional LabVIEW-based software is available for virtual experiment extension.

The FortiTestX 07 Continuous and Indeterminate Beams Apparatus is an electronically instrumented experimental unit designed for the investigation of beam deflection, support reactions, and elastic line behaviour under statically determinate and indeterminate conditions. Manufactured by SCIENTICO, this apparatus is intended for use in strength of materials, structural mechanics, and civil and mechanical engineering laboratory programmes at engineering colleges, technical universities, and research laboratories. It advances beyond dial gauge-based beam testing by incorporating electronic load cells at each support position, providing direct digital measurement of vertical reaction forces and enabling a broader range of structural analysis experiments.


Product Overview

Continuous and indeterminate beams are encountered throughout structural engineering practice — in bridge girders, building frameworks, and machine structures. Unlike statically determinate beams, indeterminate beams have more support reactions than can be resolved through equilibrium equations alone, requiring compatibility conditions and methods such as the force method or the principle of virtual work for full analysis. Experimental verification of these analytical methods is a core component of advanced structural mechanics and strength of materials courses.

The FortiTestX 07 is mounted on a compatible test frame. Up to three supports can be positioned under the beam at adjustable locations along the span, allowing single-span, dual-span, and triple-span configurations to be established. Three of the supports incorporate electronic load cells with knife-edge contacts. Each knife-edge support can be set to either a fixed position or allowed to sink by a defined displacement, enabling students to study the effect of support settlement on reaction forces and beam deflection. Two additional supports with clamping fixtures establish fixed-end boundary conditions for cantilever and other indeterminate configurations. All load cells are connected to a digital force display device, providing continuous real-time reaction readings.

Construction and System Design

The FortiTestX 07 is designed for use with a compatible test frame that provides a stable and level reference surface for all beam and support configurations. The three knife-edge load cell supports are height-adjustable and incorporate a sinking displacement mechanism that can be engaged or locked independently for each support, enabling controlled support settlement studies. The two clamping supports fix the beam end condition for indeterminate configurations. All five electronic load cells are connected to a centralised digital force display device, allowing simultaneous monitoring of all support reactions during loading. The load cells are engineered to measure vertical reaction forces while resisting the bending moment transmitted through the support contact, ensuring measurement accuracy under combined loading conditions. Beam sections are standardized to a 19 mm width across all five materials and are fully interchangeable without modification to the support or frame arrangement. The storage unit houses all components in an organised manner for repeated laboratory use.


Export and Supply Capability

SCIENTICO manufactures and supplies the FortiTestX 07 Continuous and Indeterminate Beams Apparatus to engineering institutions and laboratory equipment distributors internationally. The unit is packaged for safe transit and is suitable for supply to universities, civil and mechanical engineering departments, and technical training institutes across export markets. Customization of beam materials, load cell range, or software integration is available upon inquiry.

1. What is the key difference between the FortiTestX 06 and the FortiTestX 07?
The FortiTestX 06 uses dial gauges and articulated supports with mechanical force gauges for support reaction measurement. The FortiTestX 07 replaces these with electronic load cells connected to a digital force display device, providing real-time digital reaction readings and enabling sinking support experiments. The FortiTestX 07 also includes optional virtual testing software that extends the experimental range beyond the physical hardware.

2. What is the sinking support feature on the FortiTestX 07?
Two of the three knife-edge load cell supports can be set to sink by a defined displacement rather than remaining at a fixed height. This allows students to experimentally study the effect of support settlement on vertical reaction forces and beam deflection in indeterminate beam systems — a scenario that cannot be investigated on fixed-support apparatus.

3. How are support reactions measured on the FortiTestX 07?
Five electronic load cells — three with knife-edge contacts and two with clamping fixtures — are connected to a digital force display device. The load cells are designed to isolate vertical reaction force measurement from the bending moment present at the support, ensuring accurate and repeatable readings.

4. What virtual experiments are available with the optional software?
The optional FT-07 LabVIEW-based software simulates the hardware experiments and extends the test range to include uniform distributed loads, larger load magnitudes, and alternative specimen configurations that are not achievable with the physical weight set and beam sections alone. It is compatible with any Windows operating system.

5. What beam materials and cross-sections are supplied with the FortiTestX 07?
Fifteen beam sections are supplied across five materials — stainless steel, brass, aluminum, mild steel, and copper — each in three cross-sections: 19 x 3 mm, 19 x 5 mm, and 19 x 6 mm. This range supports comparative study of elastic modulus and geometric effects on beam deflection under identical loading and support conditions.
