SJI Joist Selection Verification Tests
In order to validate the SJI module developed verification tests were undertaken. Kシリーズ, LHシリーズとDLHシリーズはすべて、機能のピックとチェックの両方でテストされています.
ピック機能は、有効なジョイスト指定を決定し、指定された荷重と寸法条件に基づいて利用率を計算します. 検索アルゴリズムは、1 フィートあたりの質量を最小限に抑えながら、有効なジョイストを選択します.
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 (ロード, 深さ, 等…)
