SJI Joist Selection Verification Tests
In order to validate the SJI module developed verification tests were undertaken. Série K, Les séries LH et DLH ont toutes été testées sur les deux fonctionnalités pick and check.
La fonctionnalité de prélèvement détermine une désignation de poutrelle valide et calcule le rapport d'utilité en fonction de la charge et des conditions dimensionnelles spécifiées. L'algorithme de recherche sélectionne une solive valide tout en minimisant la masse par pied.
The check functionality calculates the utility of a proposed joist designation based on specified load and dimensional conditions.
Direct testing of the pick functionality was far more comprehensive than direct testing of the check functionality. This is justified as the check functionality is completed after a valid joist is selected to return the utility ratio. The check functionality is therefore implicitly tested during the pick function tests.
The term No Solution means a valid joist could not be found based on the design criteria given (charge, profondeur, etc…)
