SJI Joist Selection Verification Tests
In order to validate the SJI module developed verification tests were undertaken. Σειρά Κ, Η σειρά LH και η σειρά DLH δοκιμάστηκαν και στις δύο λειτουργίες επιλογής και ελέγχου.
Η λειτουργία επιλογής καθορίζει μια έγκυρη ονομασία δοκού και υπολογίζει την αναλογία χρησιμότητας με βάση καθορισμένες συνθήκες φορτίου και διαστάσεων. Ο αλγόριθμος αναζήτησης επιλέγει μια έγκυρη δοκό ενώ ελαχιστοποιεί τη μάζα ανά πόδι.
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 (φορτώνω, βάθος, και τα λοιπά…)
