支吊架組件荷載性能試驗適用于以地震力爲主要荷載，建築抗震設防烈度爲6度～9度的建築機電設備抗震支撐設施試驗檢驗。分別將4套支吊架組件安裝到HRJ疲勞試驗機，斜撐與主吊螺杆成45°夾角，組件試樣在水平面內的位移量不超過50mm。其他30°60°夾角的試驗值，可通過換算方式得到。組件經過15次相同力值振幅的循環加載後，繼續受到力值振幅遞增的循環荷載，達到規定的終止條件時，確定組件的試驗荷載。組件試驗循環荷載頻率爲0.1Hz。
CJ/T476-2015建築機電設備主要包括建築給水、供暖通風與空調、電氣、燃氣、消防等爲建築使用功能服務的附屬機械、電氣構件、部件和系統。抗震吊支架由錨固體、加固吊杆、抗震連接構件及抗震斜撐組成，與建築結構體牢固連接、以地震力爲主要荷載的抗震支撐系統。抗震支吊架是對機電設備及管線進行有效保護的重要抗震措施。
